Introduction to Historical Geology Emanuel Kayser's Abriss der Geologie

Abstract

IN their differences these two books bring out very clearly the difficulties that beset the teacher of historical geology (stratigraphy) to-day. An ever-increasing knowledge of the detail of local successions, and the recognition of a multitude of folding phases, combine to blur the once clear impression of stratigraphic divisions delineated by Nature with bold strokes across the whole earth. It is obvious that even the honours student cannot be expected to learn ‘world stratigraphy’ on the old lines ; the problem then becomes one of selection and deliberate omission, of so presenting the partial picture that the result is a balanced whole.
