On Materials of Solid Particles Contained in Snow and Rain Water: Part 2

[摘要] Samples of snow and rain water were collected at a site on the coast of the Hokuriku district in February and March 1970. Quantitative analysis of minerals in the solid particles contained in each sample was carried out by X-ray method. The main source regions of these particles were inferred from the analyses of the mineral composition of the solid particles and trajectories of air masses. The results are summarized as follows : (1) Most of the solid particles in snow sample were found to be soil particles blown up from the upper drainage basin of Yellow River (Loess particles). (2) The origin of the solid particles in sleet sample was very similar to that of the solid particles in the snow sample. (3) Most of the mineral particles in rain sample were considered to be soil particles originated from the upper drainage basin of Yangtze River.
