陕西汉中阜川高岭土矿地质特征与控矿因素

Geological Characteristics and Ore-controlling Factors of Fuchuan Kaolin Deposit in Hanzhong,Shaanxi Province

汉中阜川是陕西省重要的高岭土矿产资源地,高岭土含矿岩系为梁山组粘土岩地层,高岭土矿呈层状、似层状产于下二叠统梁山组煤层下部,矿石自然类型有硬质、软质高岭土两种。矿床形成主要受古构造、古气候、沉积环境及水介质条件、成岩后生作用等主要因素控制,成因类型为古风化壳沉积型。

Fuchuan of Hanzhong is an important white clay mineral resource in Shaanxi province.The ore-bearing rock series of the deposit is claystone strata of Liangshan formation,white clay ore occurs in layered form in the lower part of the coal seam of the Lower Permian Liangshan formation.The natural types of ore are hard and soft.The formation of the deposit is mainly controlled by palaeostructure,palaeoclimate,sedimentary environment and water medium conditions,diagenetic epigenesis.The genetic type is ancient weathering crust sedimentary type.
