A Study For The Structure Of Geochemical Anomaly From Dalingkou Ag-Pb-Zn Deposit In Tiantai, Zhejiang Province

As a test area, Dalingkou Ag-Pb-Zn deposit, which located in Tiantai, Zhejiang province was systematically reserched on the correlation between the main ore-forming elements'mineralization and enrichment characteristics, such as Ag, Pb and Zn, and enrichment or depletion of other elements in rocks and ores of a typical profile, a plane and middle sections. In addition, the structure of geochemical anomaly also was detailedly studied. Based on above studying results, the deep ore-body prediction method and technology were tentatively discussed furtherly. Result showed, the correlation and elements combination and classification caused by the correlation could direct the ore-body location, mineralized degree and conditions of metallogenic environment.By the study on the structure of elements geochemical anomaly in the surface rocks of a typical profile, a plane and middle sections, the structure relationship of two kinds of depleted and enriched elements at horizontal direction was discussed. Furthermore, the geochemical exploration indexes that could reflect the ore deposits location and the mineralized degree were determined for further. Then, methods of predicting deep ore-body, which based on the structural feastures of geochemical anomaly, were put forward.This paper is an attempt to predict deep ore body by studying on the deposit'element geochemistry anomaly structure features. Besides, the results also provides a new and successful case suitable for the hydrothermal type of Ag-Pb-Zn deposit geochemical exploration in the future.
