Clinoforms and clinothems are important common architectural elements in the sedimentary record of many basins worldwide. The influence that they exert on chronostratigraphic interpretations, however, is often underestimated. This especially true non-marine basins, such as Central European to Asian Neogene Paratethyan where division correlation usually based fossils environmentally sensitive mo...

Of the 24 Greenland interstadials in Last Glacial-interglacial cycle (LGIC) only five are conventionally recognised Britain. This paper aims to improve understanding of LGIC Britain from a site at Arclid, Cheshire. Sediments were characterised and luminescence used establish chronology. found that Chelford Sand Formation spans 77-47 ka with sand deposited initially by aeolian but later fluvial ...
