Prospecting indicators for Zhaojiatun skarn-type zinc-copper-silver polymetallic deposit in Huludao,Liaoning Province
摘要
Abstract
The Zhaojiatun zinc-copper-silver polymetallic deposit in Huludao of Liaoning Province is located on the southwest of Yangjiazhangzi molybdenum deposit within the Yangjiazhangzi-Bajiazi molybdenum polymetallic metallogenic belt.The ore bodies are primarily hosted in the limestone-skarn contact zone and skarn layers,with sphalerite and chalcopyrite as the dominant metallic minerals.The ores exhibit irregular granular,xenomorphic granular textures and banded or disseminated structures.The average grades are 4.27%of Zn and 3.01×10-6 of Ag for Ore Body I,6.60%Zn and 8.50×10-6 Ag for Ore Body II,and 0.74%Cu and 25.90×10-6 Ag for Ore Body III.Based on the analysis of geological characteristics,it is preliminarily inferred that the Zhaojiatun Zn-Cu-Ag polymetallic deposit is of skarn-type formed by contact metasomatism hydrothermal processes.The skarn zones,mineralized alterations,and geophysical-geochemical anomalies serve as key prospecting indicators in the area.Two prospective metallogenic target areas(No.1 and No.2)have been delineated,providing references for further exploration and prospecting efforts in the region.关键词
