Abstract

Measurement of the anisotropy of magnetic susceptibility of Westphalian sandstones from the southern part of the South Staffordshire Coalfield shows that there is a weak preferred grain orientation. There is a significant within-sample consistency of fabric lineation and the results agree with other geological evidence. The palaeocurrent pattern is complex as may be expected within a fluvial or deltaic regime. This preliminary study suggests that this magnetic fabric technique may be used to determine the detailed palaeocurrent pattern within the Upper Carboniferous of the Midland Province.
