【摘要】：采用XRF、XRD、岩相显微观察等现代检测分析技术对湖北大冶铜绿山岩阴山脚遗址东周时期地层中"风化壳"进行了化学成分及岩相组织检测分析,结合铜绿山氧化铜矿石矿物组成及地球化学特征、周围遗迹关系,初步认定"风化壳"可能是冲洗矿石后的泥流沉积(尾沙沉积)。
[Abstract]:The chemical composition and lithofacies structure of weathered crust in the strata of Yingshanjiao site of Tonglushan, Daye, Hubei Province, were detected and analyzed by means of modern detection and analysis techniques such as XRF / XRD and microscopic observation of lithofacies. Combined with the mineral composition and geochemical characteristics of Tonglushan copper oxide ore and the relationship between the surrounding relics, it is preliminarily concluded that the "weathering crust" may be the mudflow deposit after washing the ore.
