Investigations of soil genesis on glacial and glaciofluvial deposits near Kyangjin in the Langtang valley, Central Nepal, and radiocarbon analysis were carried out to quantify the intensity of soil development and to date Holocene events. Iron fractionation and weathering indices resulted in a differentiation of the soils into groups of different soil development. The first group of very young soils are developed from deposits of the Little Ice Age. They had their main zone of weathering in the top horizons. The second group of soils, mainly Inceptisols and Spodosols, indicated advances of the Lirung glacier into the valley of Langtang Khola, which took place between 3100 and 500 years B.P. At about 6000 and 4400 yr B.P. climatic fluctuations occurred characterized by accelerated solifluction and deposition of eolian material following warmer periods with humus accumulation and soil formation. The relative-age estimates were supported by radiocarbon analysis.
