Abstract
Xiahuangzhuyuan gold deposit is an important component in the Laowan gold ore belt.Based on the study on the geochemical parameters of rare elements in different formations and main rocks,space distribution and concentration zoning of anomaly elements,anomaly zoning sequences and ratios of elements,it is indicated that metallogenic elements and their content variations are closely related to stratigraphic sequences and rock types.Two-mica quartz schist of Guishan formation is the direct host country rocks,and it makes up source bed with plagioclase amphibole schist.According to zoning of anomaly element components,vertical zoning sequences and ratios of elements on different elevations,geochemical evaluation indicators are established,and can provide geochemical basis for ore prospecting in the deep and the periphery of the deposit.
