THE inlier of Carboniferous Limestone, situate within the Coal Measure area at Upper Vobster, was the subject of much controversy in the past. It was not, however, until 1912 that Dr. T. F. Sibly settled this vexed question, and showed that the inlier was a mass of Carboniferous Limestone and “Millstone Grit” superimposed upon folded Coal Measures by thrust-faulting. His paper contains a very accurate map showing the extent of the quarries and strata exposed at the time: the latter now unfortunately having been removed by further quarrying.

This paper contains a full bibliography of literature prior to his investigations and accordingly, such a list will be omitted from the present communication.CrossRefGoogle Scholar
