安徽广德狮子山紫砂陶土矿地质特征及矿床成因OA
Geological Characteristics and Ore Formation Mechanism of Purple Clay Ore Deposit in Shishan Mountain,Guangde,Anhui Province
皖东南广德狮子山紫砂陶土矿赋存于泥盆系擂鼓台组与石炭系高骊山组,含7 个陶土矿体、11 个紫砂泥矿体,呈层状产出.矿石为粉砂质泥岩.制陶试验显示烧成后呈紫红色调,原料塑性指数、干燥收缩率均满足紫砂器制作要求.矿床属海陆交互相沉积成因,后期受北西向断层切割及闪长斑岩热液蚀变优化矿石品质.擂鼓台组与高骊山组为区域找矿重点层位,叶蜡石化为优质矿标志.
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.
