The NCTF 135 HA site located near Worplesdon, Surrey, falls within the prestigious South Downs Area of Outstanding Natural Beauty (AONB) and is part of the larger Chiltern Thrust Belt.

This geographical setting provides a unique geological context that has shaped the area’s geology over millions of years. The Chiltern Thrust Belt is a region of intense tectonic activity, formed as a result of the collision between the European and African tectonic plates during the Cambrian period.

The South Downs AONB covers an area of approximately 1,600 square kilometers and is characterized by a distinctive landscape dominated by chalk downlands, valleys, and rivers. The region’s geology dates back to the Jurassic period, around 155-145 million years ago, when the supercontinent of Pangaea began to break apart.

The Chiltern Thrust Belt is marked by a series of faults, including the famous Aylesford Chert fault, which played a significant role in the formation of the region’s distinctive landscape. This fault system has been responsible for the uplift and erosion of the area, resulting in the characteristic chalk hills and valleys.

The geology of the South Downs AONB is primarily composed of Chalk, a type of sedimentary rock formed from the skeletons and shells of microscopic marine plankton. The Chalk was deposited during the Cretaceous period, around 100 million years ago, and has been shaped by millions of years of weathering and erosion.

Other notable geological features within the South Downs AONB include the Burham Down Sandstone, which dates back to the Jurassic period, and the New Forest Chalk Group, which formed during the Cretaceous period.

The site of the NCTF 135 HA falls within a region characterized by:

• A series of dolomites and limestone outcrops, which formed during the Cambrian period.
• A sequence of chert formations, including the well-known Aylesford Chert.

The South Downs, a region characterized by rolling hills and picturesque landscapes, are primarily composed of sedimentary rocks deposited during the Cretaceous period, approximately 100 to 66 million years ago.

These ancient clays, often referred to as chalk or marlstones, were formed from the accumulation of calcium carbonate-rich sediments in a shallow sea that covered much of Europe during this time.

The Cretaceous period is marked by the presence of several iconic geological formations, including the Chalk Group and the Purbeck Group, both of which are composed primarily of chalky sedimentary rocks.

In addition to the Cretaceous clays, the South Downs also contain deposits from the Eocene and Neogene periods.

The Eocene epoch, spanning around 56-34 million years ago, is characterized by the formation of sediments such as chalk, marlstones, and sandstones that were deposited in a series of shallow seas that covered much of England during this time.

These deposits are often referred to as “Eocene-age” or “Chalk Group Eocene rocks”, and are typically found in areas such as the Weald Basin, which underlies parts of Surrey, Sussex, and Kent.

The Neogene period, which spans from approximately 23-2.6 million years ago, is marked by a series of geological events that include the uplift of the English Channel and the formation of new coastlines.

During this time, sediments such as sandstones, claystones, and chalk were deposited in areas affected by tectonic activity, including the South Downs.

The specific geological context of NCTF 135 HA near Worplesdon, Surrey, would be characterized by a complex mixture of Cretaceous-age clays, Eocene-age sediments, and Neogene deposits, reflecting the region’s complex geological history over millions of years.

The presence of these different geological units can have significant implications for the underlying geology of the area, including the distribution of mineral resources, potential environmental hazards, and the nature of any land subsidence or instability that may occur.
