Trend analysis of a thin sedimentary sequence within the Upper Carboniferous of Ayrshire, Scotland

Abstract

Trend analysis was made of selected variables from a unit representing two seatearth- to- seatearth cycles within the Upper Carboniferous coal measures of Ayrshire, Scotland. A positive correlation is shown between structural level and thickness of the unit at local, but not regional level, indicating that the broad structure was initiated in late or post-Carboniferous time, but that local structural features were active during deposition. Trend analysis of clastic proportions of the unit suggest a derivation of coarse material from the northeast in a postulated model of sand lobes and sheets extending down paleoslope across a platform" of mud deposition. Individual coal-thickness variations seemingly are complex and probably subject to a mixture of controls at local and regional scales.
