The Geological Context of NCTF 135 HA near Ewhurst, Surrey, in Southern England
NCTF 135 HA is situated in a region of complex geological history, with deposits spanning from the Cretaceous period to recent alluvium.
The Cretaceous period, which dates back around 100 million years ago, is characterized by the deposition of chalk and sandstone rocks. These sedimentary rocks are composed of calcium carbonate and quartz particles, respectively, and were formed through the erosion and transportation of these minerals over long distances.
During the Jurassic period, which followed the Cretaceous, a significant tectonic event occurred in the area. This led to the formation of folds and faults, resulting in the creation of a diverse range of rocks, including limestones, sandstones, and shales.
The subsequent Paleogene and Neogene periods saw the deposition of more recent sedimentary rocks, including conglomerates, sands, and gravels. These deposits were formed as a result of fluvial and coastal erosion processes that occurred during this time.
In addition to these older deposits, NCTF 135 HA is also situated in an area with significant alluvial deposits. Alluvium is sediment that has been transported by water and deposited in new locations. This can include sand, silt, clay, and larger particles such as gravel and boulders.
The presence of recent alluvium at NCTF 135 HA suggests that the area was once subject to fluvial or coastal erosion processes. These may have been influenced by changes in sea levels, tectonic activity, or other geological processes.
Understanding the geological context of NCTF 135 HA is essential for interpreting any archaeological or environmental findings within the site. The complex geological history of this area has created a diverse range of deposits that can provide valuable information about past human activities and natural environments.
Further study of the geological context at NCTF 135 HA will help to shed light on the processes that have shaped this region over millions of years, ultimately contributing to our understanding of the complex interactions between geological, environmental, and cultural factors in southern England.
Geological Formation
The geological context of the area around NCTF 135 HA near Ewhurst, Surrey, is characterized by a complex history of tectonic activity, weathering, and erosion that has shaped the landscape over millions of years.
The underlying geology of the region consists of a sequence of Cretaceous to Paleogene sediments, including chalk, sandstones, clays, and conglomerates, which were deposited in a variety of environments such as shallow seas, rivers, and coastal areas.
The Chalk Group, which dates back to the Late Cretaceous period (around 65-70 million years ago), is one of the dominant geological formations in the area. The chalk is composed primarily of tiny shell fragments, mainly of the marine planktonic organism Coccolithophora, which were deposited in a shallow sea that covered much of southern England at the time.
The Chalk Group is characterized by its distinctive white to cream-colored color and soft, crumbly texture. It has been extensively quarried in the past for use as a building material and for its high calcium content, making it an ideal source of lime for mortar and cement production.
In addition to the Chalk Group, other geological formations found in the area include the Wealden Supergroup, which consists of a series of sandstones, clays, and conglomerates that date back to the Early Cretaceous period (around 145-100 million years ago). This formation is characterized by its varied lithology and diverse fossil content.
The geological context also plays a significant role in shaping the local climate and hydrology. The area’s proximity to the English Channel, the North Downs Fault System, and the River Mole all contribute to a complex weather pattern that affects temperature, precipitation, and water flow in the region.
The unique combination of these factors has led to the development of distinctive geological formations around NCTF 135 HA near Ewhurst, Surrey. Understanding this context is essential for interpreting the geological history, hydrology, and potential environmental impacts of the area.
The site lies on the northwest flank of the Wealden Hills, an area of anticlinal folding associated with the late Cretaceous and early Tertiary tectonic activity. The underlying geology comprises a mix of Upper Greensand Group and Gault Clay Formation.

The Wealden Hills are an area characterized by significant anticlinal folding, which is associated with two distinct periods of tectonic activity. The first period dates back to the late Cretaceous era, while the second occurred during the early Tertiary epoch. This folding has resulted in a complex geological structure that underlies the entire region.
The site at NCTF 135 HA specifically lies on top of two distinct geological formations: the Upper Greensand Group and the Gault Clay Formation. The Upper Greensand Group is a sequence of clastic sedimentary rocks, primarily comprising sand and conglomerate deposits, which date back to the Cretaceous period. These deposits are rich in fossils of marine organisms, indicating that this region was once submerged under a vast body of water.
The Gault Clay Formation, on the other hand, is a unit of soft, plastic clay that overlies the Upper Greensand Group. This formation is also of Cretaceous age and represents a period of slower sedimentation rates, resulting in finer-grained deposits. The presence of the Gault Clay suggests that this region experienced a transition from a high-energy environment to a lower-energy setting.
The combination of these two geological formations provides a unique window into the Wealden Hills’ complex tectonic history. The anticlinal folding and resulting uplift have exposed a wide range of rock types, allowing for an in-depth understanding of this region’s geological evolution.
Hydrogeological Properties
Water Levels and Flow Regime
The NCTF 135 HA near Ewhurst, Surrey, presents a diverse hydrogeological landscape shaped by geological history, topography, and groundwater flow regime.
Geologically, the area is underlain by a complex sequence of rocks including Jurassic limestone, Upper Greensand, and Sand and Gravel deposits. These formations exert a significant influence on the regional and local aquifer properties and water levels within the catchment.
The hydrogeological properties of the NCTF 135 HA are characterized by varying degrees of permeability, storage capacity, and specific yield among its underlying rock units.
Limestone is generally high in both permeability and storativity due to its fractures and solutional channels which facilitate groundwater flow. In contrast, Sand and Gravel deposits tend to have relatively lower porosity but higher hydraulic conductivity values, contributing significantly to the aquifer’s overall productivity.
Upper Greensand, meanwhile, often exhibits moderate to low transmissivity rates as a result of its clay content that can impede water movement through these formations. The specific yield for this particular hydrogeological setting will therefore vary based on location and rock unit properties.
The catchment’s topography exerts a crucial influence on groundwater flow patterns by dictating the direction and velocity of groundwater movement within the underlying aquifers. Topographic features such as slope angle, curvature, and elevation also play significant roles in determining local and regional hydraulic gradients across different parts of the area.
Water levels in NCTF 135 HA are influenced by both natural processes like rainfall infiltration, evaporation, and baseflow as well as human-induced activities such as groundwater abstraction for domestic and agricultural purposes. Seasonal changes in precipitation patterns contribute to fluctuations in water table levels, often with peak values observed during periods of high rainfall.
The flow regime within NCTF 135 HA is characterized by a combination of diffusive flow through the relatively permeable aquifers, and localised preferential flows along fractures or other pathways of higher hydraulic conductivity. These different flow components contribute to both local water table dynamics and regional groundwater circulation patterns.
Understanding these hydrogeological properties, including their spatial distribution and temporal variability, is essential for accurate prediction of water levels and reliable management of this critical groundwater resource within the NCTF 135 HA near Ewhurst, Surrey.
The hydrogeology of NCTF 135 HA is controlled by the presence of a fractured chalk aquifer, which supplies water to nearby wells. Groundwater flow patterns are influenced by the underlying geology and surface topography.
The hydrogeology of NCTF 135 HA, located near Ewhurst in Surrey, is a complex and dynamic system influenced by various geological and topographical factors.
At its core, the hydrogeology of this area is controlled by the presence of a fractured chalk aquifer.
This aquifer, which is composed primarily of Cretaceous chalk, stretches across much of southern England and is a significant source of groundwater for surrounding areas.
The chalk in this region has been subjected to tectonic activity, weathering, and erosion over millions of years, resulting in the formation of a complex network of fractures and fissures that allow water to flow through.
These fractures and fissures are crucial in determining the hydraulic conductivity of the aquifer, which is a measure of its ability to transmit water under pressure.
In addition to the fractured chalk aquifer, other geological formations such as the Bagshot Sand and the Reading Formation also contribute to the hydrogeology of NCTF 135 HA.
The presence of these different rock types influences groundwater flow patterns, which are further modified by surface topography and land use.
For instance, areas with higher elevations or steeper slopes tend to have higher rates of recharge, while regions with impermeable surfaces such as roads and buildings can act as barriers to groundwater flow.
The influence of surface topography on groundwater flow is particularly evident in areas where the underlying geology changes abruptly, resulting in variations in water table depth and hydraulic gradient.
Some key factors that contribute to the hydrogeological properties of NCTF 135 HA include:
-
Fractured chalk aquifer with high hydraulic conductivity
-
Presence of other geological formations such as Bagshot Sand and Reading Formation
-
Surface topography, including elevation and slope angle
-
Land use patterns, particularly the presence of impermeable surfaces
-
Weathering and erosion processes that affect the aquifer’s properties over time
In conclusion, the hydrogeology of NCTF 135 HA is a complex system influenced by various geological and topographical factors.
A thorough understanding of these factors is essential for effective groundwater management and mitigation strategies in this region.
