Description: Most of the oldest Qμaternary deposits date to the upper part of the Early Pleistocene Series, which has an age range of <1.81 to 0.78 Ma. The deposits are strongly weathered, and associated glacial lake deposits have reversed geomagnetic polarity indicating a pre MBB age of over 0.78 Ma. Middle Pleistocene deposits are moderately weathered, and associated glacial lake deposits have normal geomagnetic polarity indicating ages from 0.78 Ma to 126 kyr, the OIS 6 to 5e boundary (OIS ==MIS). Deposits of Last Interglacial age are defined by fossil pollen/vegetation sequences and by Uranium series dating of marine deposits, and are referred to OI Substage 5e. Last Glaciation age deposits are little weathered and include those dating to OI Substages 5d, 5c, 5b, 5a and Stages 4, 3 and 2. Holocene sediments of OIS 1 age are younger than 11.7 k yr before AD 2000.
