The Last Glacial Maximum ( LGM ), also referred to as the Last Glacial Coldest Period, [1] was the most recent time during the Last Glacial Period that ice sheets were at their greatest extent 26 ka – 20 ka ago. [2] Ice sheets covered much of Northern North America, Northern Europe, and Asia and profoundly affected Earth 's climate by causing ... Chronostratigraphy ('time-rock stratigraphy') is the branch of stratigraphy concerned with the application of time to rock successions, the ultimatel goal of which is the establishment of a globally applicable standard time-scale. The chronostratigraphical scale originated as a relative one which was been built up, like a jig-saw puzzle ...Abstract. Three ice cores to bedrock from the Dunde ice cap on the north-central Qinghai-Tibetan Plateau of China provide a detailed record of Holocene and Wisconsin-Würm late glacial stage (LGS) climate changes in the subtropics. The records reveal that LGS conditions were apparently colder, wetter, and dustier than Holocene conditions.

The term "Wisconsinan Glaciation" refers to the last major glacial episode that affected North America, more properly referred to as the Wisconsinan Stage (Black et al., 1973; Fulton, 1989; Clark and Lea, 1992) (Figure W1).The term should be restricted to the deposits and events of the Laurentide Ice Sheet (LIS; see Laurentide Ice Sheet), which extended from the Canadian Arctic coast to ...A pre-Wisconsinan age is assigned to the argillic horizon of pa- leosol complex 2 because development of such a well expressed argillic hori- zon is unlikely during Wisconsinan time (FOLLMER 1983).

Both deposits indicate that the crust was isostatically depressed below the late Wisconsinan eustatic sea level and that deglaciation and marine submergence occurred simultaneously.

The low-relief landscapes offer very few exposures of their internal composition. Erosion on a large scale is the key to the geological origins of the Iowan Surface.
