Beeby Thompson,

Geochemistry and Geologic Mapping

In the Report of an Excursion of the Geologists' Association to Catesby in July 1896, I have already given an account of the geology of 6 miles of the new extension to London of the Manchester, Sheffield, & Lincolnshire Railway (since re-named the Great Central Railway), reaching from Catesby to a little beyond Woodford: that is, from the 62nd to the 68th mile. The sections exposed were chiefly in Middle and Upper Lias; but, at the northern end of the Catesby tunnel, the capricornus -zone of the Lower Lias was partly cut through, all the characteristic fossils of that zone being found. The portion of the line which it is now proposed to describe, from Rugby to Catesby, extends from the 52nd to the 62nd mile. Two papers have already dealt with parts of it, but they necessarily left much detail to be filled in; indeed the new matter afforded by excavations made since the publication of those two papers would probably constitute a sufficient justification for a third. I had seen no part of the sections about to be described until August 1896, and the exceptionally wet autumn of that year prevented a thorough examination of the slopes themselves, such as I fully intended to make. On renewing my acquaintance with the line, in the spring of 1897, I found some of the more southerly cuttings finished and grassed over. Fortunately the more northerly cuttings, towards Rugby, were developing their most interesting parts. I am much indebted to Mr. A.
