Holocene lithificates at the slopes of the Untersee mountain valley, East Antarctica

The lower part of the slopes of the Untersee mountain valley, East Antarctica, were found out to be locally covered with lithificates (both carbonate-free and carbonate-poor), which occur in three modes: crusts, films, and impregnates. All of them cover Late Pleistocene moraine material and consist...

Description
Summary:	The lower part of the slopes of the Untersee mountain valley, East Antarctica, were found out to be locally covered with lithificates (both carbonate-free and carbonate-poor), which occur in three modes: crusts, films, and impregnates. All of them cover Late Pleistocene moraine material and consist of a mixture of lacustrine sedimentary material and the filling material of moraines. A mechanism is suggested to account for the genesis of these lithificates.
