Publisher's Synopsis
Excerpt from The Geology of Rutland and the Parts of Lincoln, Leicester, Northampton, Huntingdon, and Cambridge: Included in Sheet 64 of the One-Inch Map of the Geological Survey, With an Introductory Essay on the Classification and Correlation of the Jurassic Rocks of the Midland District of England
IN obedience to a very general demand for the more rapid completion of the maps illustrating the coal-producing districts of the country, the officers of the Geological Survey of Great Britain, who were employed in tracing northwards the boundaries of the Jurassic Strata, were nearly twenty years ago transferred to the northern counties. Thus the mapping of the Lias and Oolites remained during a considerable interval in abeyance. This period was, however, marked by many important advances made by geologists in their knowledge of the rocks in question, and by the introduction of new principles and methods of classification. The views gradually elaborated by Quenstedt, Fraas, Marcou, Oppel, and others on the continent, were applied by Dr. Wright and other geologists to the rocks of this country, and the necessity for modifications of the classification, adopted in some of the former publications of the Survey, were thereby rendered manifest. In particular, we may mention the conviction arrived at by many geologists, that certain rocks supposed to be of Great Oolite age, ought in fact to be classed with the Inferior Oolite. Having been engaged during six or seven years in preparing a geological map and description of that interesting county so little known to geologists Lincolnshire, I had been gradually led to the adoption of the views referred to above; and in 1867, when it was determined to resume the mapping of the Jurassic rocks, I was requested to join for a time the staff of the Geological Survey, and to devote my attention to the country intermediate between Lincolnshire and the districts already mapped. It soon became clear to me that not only would the doubtful beds have to be classed with the Inferior Oolite, but, that, in consequence of the very local character of many of the formations in the district, a new classification and nomenclature was rendered absolutely necessary in order to adequately represent them.
