Abstract:

This paper present s the resultant of valent form t race gold by the typical examples f rom the middle part of the Bangonghu Lake to Nujiang River mineralization belt, Tibet. The expermental fact indicates that Au3 + and Au0 are closely related in the soils samples,the correlation coefficient (r) is 0.96, ∑Au and (Au3 + + Au+) are correlative in the st ream sediments samples, r =0.50. For example above ,the source and gensis of Au0,Au3+ and Au+,and its significance of ore-prospecting have been discussed.

Key words: soils (slop wash), stream sediments, valent form trace gold, analysis, lakes-marsh lands of plateau
