Study on Element Association Zonation of Stream Sediments in Shitai-Huangshan Area in Southern Anhui Province
摘要
Abstract
Based on stream sediment survey data with the scale of 1∶50000 in Shitai-Huangshan area in southern Anhui province,by using R type factor analysis,five common factors have been extracted.By u-sing factor scores,geochemical zoning has been carried out.Combining with geological background,each geochemical zone have been analyzed and evaluated.It is showed that factor F1(Pb,Zn,Ag,Cu)has a variance contribution rate of 22.092%,and factor F2(As,Sb,Cu)has a variance contribution rate of 16.554%.It reflects geochemical background differences between Jiangnan Massif and the Lower Yangtze Massif,and effectively indicates polymetallic mineralization information in the area.Factor F3(Ba,Mo,Cu,Ag)has a variance contribution rate of 16.378%.Its element assemblage is highly similar to that of black shale series.Its spatial distribution is generally consistent with the outcrop areas of Cambrian and Ordovician strata.It is a key indicator for identifying black shale series and related molybdenumvanadium mineralization.Factor F4(W,Bi)is related to granitic magmatic activity and geochemical characteristics of intrusions.It can indicate tungsten mineralization potential.Factor F5(Au)directly reflects the enrich-ment characteristics of gold mineralization.This study systematically reveals the relationship between re-gional element assemblages and geologicalmetallogenic processes.It will provide a geochemical basis for further delineation of prospecting targets and indepth study of metallogenic regularities.关键词
