| Abstract/Notes | Previous to the year 1913 the English Kimmeridge Clay was divided into two zones only, which were believed tq be “intimately blended”. In 1913 Dr. H. Salfeld instituted a more detailed subdivision of eleven zones, the upper three of which constitute the Upper Kimmeridge Clay as since defined by Dr. F. L. Kitchin. Salfeld's sequence of zones was emended in 1922 by Messrs. Chatwin and Pringle, who showed that at Swindon the zone of Pectinatites pectinatus (Phill.) occurs below the Swindon Clay, and not above it, as Salfeld had supposed. In the early part of last year Mr. S. S. Buckman also presented a similar scheme of zones, and subdivided Salfeld's zone of P. pectinatus, which he placed in the Lower Portland, as in Salfeld's original scheme. |
