Abstract
Based on analyzing enrichment and dispersion of 19 kinds of elements gained from stream sediment survey with the scale of 1∶50000 in Hatu area in Qinghai province, the paragenetic association of elements, enrichment regularity and element anomaly have been studied.It is pointed out that major ore-forming elements are W, Au, Ni, Bi, Sb, Ag, Pb, Mo, Cr, As and Cu.Three ore-forming prospecting areas have been circled as well.Simple verification work has been carried out in prospecting area, many polymetallic mineralization points and information have been newly discovered.It is proved that comprehensive anomaly of stream sediment survey is really existed.The direction of exploration work in this area has been pointed out.关键词
