安徽广德狮子山紫砂陶土矿地质特征及矿床成因
Geological Characteristics and Ore Formation Mechanism of Purple Clay Ore Deposit in Shishan Mountain,Guangde,Anhui Province
摘要
Abstract
A large-scale zisha clay deposit was confirmed in Shizishan,Guangde(southeastern Anhui).Orebodies occur in the Devonian Leigutai and Carboniferous Gaolishan Formations,comprising 7 pottery clay and 11 zisha clay layers.The ore is argillaceous siltstone dominated.Ceramic tests verify plasticity indices,firing hues and drying shrinkage,meeting production standards.The deposit formed in paralic sedimentary environments,later enhanced by NW-trending faults and hydrothermal alteration from diorite porphyry.The Leigutai and Gaolishan Formations are priority prospecting strata,with pyrophyllitization indicating high-quality ore.关键词
