4-594: The Malvern Line or Malvern Lineament is the name applied to a north-south aligned lineament which runs through the Malvern Hills of western England and extends southwards towards Bristol and northwards past Stourport . It consists of a series of faults and folds which have the effect of bringing old Malvernian rocks to the surface. Being largely hard igneous rocks, the Malverns Complex rocks have resisted erosion better than those of

Lineament A lineament is a linear feature in a landscape which is an expression of an underlying geological structure such as a fault . Typically a lineament will appear as a fault-aligned valley, a series of fault or fold-aligned hills, a straight coastline or indeed a combination of these features. Fracture zones , shear zones and igneous intrusions such as dykes can also be expressed as geomorphic lineaments. Lineaments are often apparent in geological or topographic maps and can appear obvious on aerial or satellite photographs. There are for example, several instances within Great Britain . In Scotland
12-809: The Great Glen Fault and Highland Boundary Fault give rise to lineaments as does the Malvern Line in western England and the Neath Disturbance in South Wales . The term 'megalineament' has been used to describe such features on a continental scale. The trace of the San Andreas Fault might be considered an example. The Trans Brazilian Lineament and the Trans-Saharan Belt , taken together, form perhaps
16-679: The surrounding countryside and result in a striking line of hills of which the Malvern Hills are the most impressive. The Abberley Hills to their north also form a part of this lineament. This line is considered to mark the edge of two terranes - two once separate fragments of the Earth's crust now joined as one - the Wrekin Terrane to the west and the Charnwood Terrane to the east.
