Abstract
Synopsis: Borehole data for part of the Namurian (E 1 Zone) east of Stirling show that a single thick bed of shale, known as the Black Metals, passes shorewards into a dominantly sandy succession. Trend analysis of these data has revealed features not previously recognised in an earlier study. These features include: (1) a rather abrupt transition between a shelf-like area near Stirling and the differentially subsiding Kincardine Basin to the east, and (2) a tongue of sand that extends south-westwards from Saline and corresponds to one of the axes of maximum subsidence.
