Geology of NCTF 135 HA near Warlingham, Surrey

The Groundwater Flow System

The geology of the area around NCTF 135 HA near Warlingham, Surrey, is characterized by a complex mix of geological formations that have played a significant role in shaping the local landscape and groundwater flow system.

The underlying geology of the area consists primarily of Paleogene sediments, including sandstones, grits, and clays, which were deposited during the Eocene epoch. These sedimentary rocks are typically divided into two main units: the Lower Greensand Group (LGG) and the Upper Greensand Group (UGG).

The LGG is comprised of coarse-grained sandstones and grits that formed in a shallow marine environment. This unit is characterized by a high degree of cross-bedding and ripple marks, indicating a dynamic depositional environment. The UGG, on the other hand, consists of finer-grained sediments, including silty clays and sandy siltstones, which were deposited in a deeper marine environment.

Overlying the Paleogene sediments are deposits of Pleistocene age, including glacial till and fluvioglacial sands. These deposits were formed during the most recent ice age, which ended around 11,700 years ago. The glacial till is typically coarse-grained and consists of a mixture of rock debris, soil, and sediment.

The groundwater flow system in this area is primarily influenced by the Paleogene sediments. The sandstones and grits of the LGG are highly permeable and allow for easy water infiltration, while the clays and silty clays of the UGG are less permeable and act as a barrier to prevent further water entry.

As groundwater flows through the sandstones and grits, it encounters fractures, faults, and other geological structures that can control its path. These features can be exploited by aquifers to store and transmit large volumes of water. In this area, several major fractures and fault zones have been identified, including the Warlingham Fracture System.

The Warlingham Fracture System is a complex network of faults and fissures that extends over several kilometers in all directions. This system has played a significant role in controlling groundwater flow and storage in the area. The fractures are typically vertical or near-vertical and can be up to 10 meters long, allowing water to flow rapidly through the rock.

The permeability of the Paleogene sediments also varies significantly depending on the specific formation. The sandstones and grits of the LGG have a high hydraulic conductivity, while the clays and silty clays of the UGG are much less permeable. This variation in permeability can lead to the formation of distinct groundwater flow paths and zones.

Groundwater in this area is primarily recharged from precipitation and surface water bodies, including rivers and streams. The most significant recharge areas are typically found near the base of hills and slopes, where water has a greater opportunity to infiltrate the soil and underlying rock.

The flow system in this area can be characterized as unconfined, meaning that it does not have a distinct water table. Instead, groundwater flows freely into and out of the sedimentary rocks, driven by gravity and hydraulic gradients.

Overall, the geology of NCTF 135 HA near Warlingham, Surrey, has played a significant role in shaping the local groundwater flow system. The complex mix of Paleogene sediments and Pleistocene deposits has created a unique set of geological features that control water infiltration, storage, and flow.

Underlying Rock Formation

The underlying rock formation near NCTF 135 HA in Warlingham, Surrey can be described as a complex sequence of rocks that date back to the Early Cretaceous period, approximately 125 million years ago.

The area is underlain by a series of sedimentary and igneous rocks that have been subjected to various tectonic and geological processes over time. The dominant rock formations in the area include:

1. Flint chalk: This type of chalk is composed mainly of flint, a type of chert that is rich in silica and has a characteristic hexagonal crystalline structure.

2. Sandstone and claystone: These sedimentary rocks are composed of sand-sized particles and clay minerals respectively, and can be found in various unconformities and fault zones throughout the area.

3. Volcanic rock: Small pockets of volcanic rock, including andesite and basalt, can be found in the area, particularly in areas where there has been tectonic activity.

The geological history of the area is characterized by a sequence of events that include:

1. Deposition of flint chalk: During the Early Cretaceous period, large amounts of flint chalk were deposited in the area, which later became compacted and cemented together to form a solid bedrock.

2. Tectonic activity: The area experienced various tectonic events, including faulting and folding, which caused the rocks to deform and become distorted.

3. Volcanic activity: Small volcanic eruptions occurred in the area, resulting in the formation of small pockets of volcanic rock.

The flint chalk that underlies NCTF 135 HA is a key feature of the local geology. It has been eroded and weathered over time, but its distinctive hexagonal crystals can still be seen on the surface in areas where it has been exposed through tectonic activity or erosion.

The presence of sandstone and claystone in the area indicates that the flint chalk was deposited in an environment with a high energy level, such as a river or sea bed. The volcanic rock also suggests that there may have been areas of tectonic activity near the site where magma rose to the surface.

It is worth noting that the geology of the area is complex and has been influenced by various geological processes over time. Further study and analysis are needed to fully understand the geological history of NCTF 135 HA.

Within this formation, the site is situated within the Bajocian age sands and clays. This geological period spans from approximately 170 million to 165 million years ago, during the Middle Jurassic.

The Bajocian age is distinguished by the presence of specific fossil species, including belemnites and ammonites, which are characteristic of this age group. These fossils provide crucial evidence for dating the site’s geological history.

The Chalk Group itself is composed primarily of chalk rock, a sedimentary formation that was deposited during the Cretaceous period, approximately 100-65 million years ago.

Geologically, the Chalk Group is considered a “keystone” formation in the UK, providing a distinctive geological signature that has been used to define the stratigraphic boundaries of various regions. In this case, the Bajocian age sands and clays are a key component of the Chalk Group.

From a petrological perspective, the chalk rocks at NCTF 135 HA exhibit characteristic features such as the presence of calcite crystals, which have formed through the precipitation of calcium carbonate from seawater. This process, known as “chemical precipitation,” is thought to have occurred during the Jurassic period.

Microscopically, the chalk rocks display a range of textures and structures, including porosity, permeability, and fractures. These features are a result of compaction, cementation, and diagenetic processes that have shaped the rock over millions of years.

The stratigraphic position of NCTF 135 HA within the Bajocian age sands and clays is likely to be near the base or middle of this geological unit. This positioning suggests that the site may be in an area where sedimentation was initially rapid, followed by periods of slower deposition.

From a geotechnical perspective, the chalk rocks at NCTF 135 HA are generally considered stable and resistant to erosion. However, localized areas of weakness or heterogeneity may exist due to factors such as groundwater flow, tectonic activity, or changes in depositional conditions.

The combination of geological, petrological, and geotechnical characteristics makes the NCTF 135 HA site an important location for understanding the geological history of the area. Its position within the Bajocian age sands and clays provides valuable insights into the tectonic, climatic, and sedimentological processes that have shaped this region over millions of years.

These rocks are characterized by high levels of calcium carbonate and potassium-rich minerals, which have contributed to their distinctive chemical composition.

The local aquifer properties in this area are influenced by the complex interplay between the hydrogeological framework, groundwater flow paths, and hydraulic head distribution. The aquifer is primarily composed of fractured sandstones, siltstones, and clays that have been subjected to various stages of diagenesis and cementation.

The permeability of the local aquifer varies widely depending on the specific lithology, with sandstone units displaying the highest levels of hydraulic conductivity. However, even in these units, permeability can be affected by factors such as diagenetic alterations, fracture development, and localized compaction.

Water tables within this area exhibit a high degree of variability due to the complex hydrogeological setting, which involves multiple aquifers and a dynamic interaction between the surface water system, groundwater flow paths, and local topography.

Hydrological responses in the NCTF 135 HA area are characterized by significant seasonal variations, with increased recharge during autumn and winter months. This is due to the presence of impermeable clay units that dominate the uppermost part of the aquifer sequence, which effectively act as a “barrier” to groundwater movement during drier periods.

Long-term groundwater flow patterns in this area are influenced by regional tectonic and geomorphological processes. The proximity to major fault lines has resulted in localized zones of deformation that have affected the local hydrogeological system, contributing to variations in hydraulic head and water quality.

The geochemical characteristics of the NCTF 135 HA aquifer water reflect the complex geological setting of the area. Groundwater samples exhibit a range of chemical parameters, including pH, conductivity, and nutrient levels, which are influenced by the interaction between local hydrogeological processes, seasonal variations in recharge, and regional groundwater flow patterns.

Nature Conservation Designations

The area under consideration, NCTF 135 HA near Warlingham, Surrey, falls within a number of **Nature Conservation Designations**, which provide a framework for managing the environment and balancing human development with conservation interests.

A key aspect of this regulatory framework is the *Wildlife and Countryside Act 1981*, which gives protection to certain species, habitats and land features. In this area, the Act applies to a number of **Special Areas of Conservation (SACs)**, including the Surrey Heath Common SAC and the Farleigh Down SAC.

The *European Communities’ Habitats Directive* is also applicable in this region, which requires member states to maintain or improve the status of designated habitats. The directive provides a framework for protecting and conserving **natural habitats**, such as heathland and grassland, which are of particular importance in this area.

Additionally, the *Natura 2000* network of sites is present in the area, which aims to conserve **biodiversity** at a European level. Natura 2000 sites are designated under both the Habitat Directive and the *Birds Directive*, and provide a framework for managing human activities that may impact on the environment.

The Surrey Heath Common SAC is also part of a larger *Site of Special Scientific Interest (SSSI)*, which recognizes its importance for **botanical** diversity. The SSSI designation provides additional protection for this area, in addition to its status as an SAC under the Wildlife and Countryside Act 1981.

The Farleigh Down SAC is protected by the *Countryside and Rights of Way Act 2000*, which gives rights of way over most land in England and Wales. This includes the right to walk on foot, to horse ride and to bike ride, while also providing protection for **wildlife habitats**.

The Surrey Heath Common SAC is also subject to *Conservation Gains Licensing Scheme (CGLS)* requirements, which aim to promote **conservation value** in any development proposals. CGLS involves requiring developers to provide additional conservation benefits, such as habitat creation or enhancement.

Furthermore, the area under consideration falls within the *Green Belt*, a designation that protects rural areas from *urban sprawl* and ensures that development is balanced with the need for **open spaces**. The Green Belt is a key element of Surrey’s planning policies, which aim to maintain the county’s natural beauty and character.

The *Local Plan* for Surrey sets out the county’s planning policies, including those related to nature conservation and environmental protection. This plan provides a framework for managing development in the area, while balancing human needs with the need to protect and enhance the **environment**.

Overall, the regulatory framework in place for NCTF 135 HA near Warlingham, Surrey, is designed to protect the **natural environment** and conserve biodiversity. The Nature Conservation Designations and other relevant policies provide a strong foundation for managing development in this area, while also ensuring that human needs are balanced with environmental concerns.

The site is situated near the Mole Valley Park Country Park, an Area of Outstanding Natural Beauty, and thus falls under the Countryside and Rights of Way Act 2000’s protection mechanisms.

The National Cycle Tactics Framework (NCTF) for 135HA near Warlingham, Surrey, is a sensitive area that requires careful consideration of regulatory frameworks and environmental concerns.

This site is situated in close proximity to the Mole Valley Park Country Park, an Area of Outstanding Natural Beauty (AONB), which brings it under the protection mechanisms outlined in the Countryside and Rights of Way Act 2000 (CRoW). This legislation provides a robust framework for balancing human activities with environmental conservation.

The CRoW Act sets out specific provisions for managing the countryside, including designations such as Sites of Special Scientific Interest (SSSIs), Areas of Outstanding Natural Beauty, and Areas of Great Natural Beauty. The Mole Valley Park Country Park is one such designation, which recognizes its outstanding natural beauty and ecological importance.

The NCTF 135HA near Warlingham, Surrey, must therefore comply with the CRoW Act’s requirements for minimizing environmental harm and promoting sustainable development. This includes measures to protect and enhance habitats, conserve biodiversity, and maintain the area’s natural character.

The Countryside and Rights of Way Act 2000 also places duties on the local authority to ensure that any planning permission granted is compatible with the protection of the environment. In the case of NCTF 135HA near Warlingham, Surrey, this means that any proposals for development or infrastructure must be carefully assessed against environmental concerns.

One key area of concern is the potential impact on habitat creation and connectivity. The Mole Valley Park Country Park is an important habitat for a range of flora and fauna species, including birds, butterflies, and wildflowers. Any changes to the site could disrupt these habitats and compromise biodiversity.

Climate change mitigation measures are also crucial in this context. As global temperatures rise, sensitive ecosystems like those found in the Mole Valley Park Country Park become increasingly vulnerable to climate-related stressors such as droughts and heatwaves.
