Glaciological Expedition of Nepal, Contribution No. 77

Abstract

During the winter of 1975, two core drillings of lake sediments were carried out in Tsola-Tso, Khumbu Himal and two cores, 1.99 and 3.07 m long, were obtained. Preliminary observations of the core lithofacies were made and are summarized as follows. 1) The lithofacies show the alternation of fine and coarse materials. 2) The thickness of each layer varies from 0.5 to 15 cm. 3) The core is classified into three part from the lithofacies, that is, top to 90 cm depth, 90 to 150 cm depth and below 150 cm depth.
