There, the substantial London Clay bedrock ridge (Danbury-Tiptree ridge) formed a major, insurmountable barrier to the Anglian ice sheet (Middle Pleistocene, Anglian Stage, 480-420 ka BP) at its southern

The glacial sequences are underlain by fluvial sands, of considerable economic importance, that include Early Devensian deposits referred to the Chelford Interstadial (c.100 ka).

Indeed the change from the 40 ka to the 100 ka cyclicity appears to be accompanied by an important increase in the intensity of supply of sedimentary detritus and thus a

supervised by Professor Sir Nicholas Shackleton (Cambridge). A multi-proxy analysis of the older section (160 to 141 cal ka), of MarineIsotope Stage 6 (MIS 6) from the high-sedimentation rate ... One main ice rafting period between 158 and 153 cal ka was

Mediterranean evergreen taxa appear 128 ka BP, indicating the full inception of interglacial climate.

Two fossil rich volcanic tephra layers exposed in a quarry at Eppelsberg, 40K / 40Ar dated at around 223 6 ka, were investigated along with strikingly similar material found in around 1860

Orbital obliquity at 41 ka cycles which had dominated the earlier part of the Pleistocene was superceded progressively about a million years ago by a 100 ka rhythm of orbital eccentricity,
