The Loch Lomond Readvance moraines of Mull and Menteith

Abstract
Synopsis: A radiocarbon date of 11 330±170 b.p . for shells from the Kinlochspelve Moraine on the Isle of Mull indicates that a readvance of ice took place there during Zone III. The ice apparently scooped up marine deposits laid down during the preceding Zone II (Alleröd) climatic amelioration. Analysis of pollen from clays in both the Kinlochspelve and Menteith moraines substantiates this opinion and together with radiocarbon dates and geomorphological evidence enables correlation of both moraines with the Loch Lomond Readvance. On Mull the mapping of moraines and thick drift deposits indicates that an ice cap and several separate glaciers existed on the island at this time.
