Alderbury-Mottisfont Syncline

From Wikipedia, the free encyclopedia

The Alderbury-Mottisfont Syncline is an east–west trending fold in the Cretaceous chalk of Hampshire. It lies to the north of the Dean Hill Anticline and south of Salisbury Plain.

Structure

[edit]

The syncline runs west about 16 kilometres (9.9 mi) from the River Test near Mottisfont to the Avon at Alderbury, south-east of Salisbury.[1]

The centre of the syncline is occupied by palaeogene rocks of the Reading Formation, London Clay and Wittering Formation. To the north and south the chalk emerges.[2][3] At the western end to the south-east of Salisbury the structure is cut by the Mere Fault.[4]
