James W. Kirkby,

Geochemistry and Geologic Mapping

In the present communication I propose to speak of the geology and palæontology of the Permian strata that lie between the towns of Pontefract and Knottingley, on the one hand, and Tickhill and the village of Maltby, on the other. In doing so my chief objects are, first, to endeavour to determine the equivalency of the subdivisional groups of these strata with those of the adjoining county of Durham; and second, to throw some additional light, if possible, upon the distribution of Permian species south of the Durham area. Towards the accomplishment of these objects I have made two visits to the district in question—one in 1854, and the other during the summer of 1859. Prof. Sedgwick has already described the geology of this region in his admirable memoir “On the Geological Relations and Internal Structure of the Magnesian Limestone.” Prof. Phillips has also noticed some of its features in a short paper “On the Geology of Ferry Bridge and its Vicinity,” published about the same period as the preceding. And since the publication of these papers, Mr. H. Clifton Sorby and Mr. Edward W. Binney appear to have pursued investigations in the same district, though the results have not been published J. Sir Roderick Murchison has also alluded to certain points of its geology in the last edition of ‘Siluria.’
