湖北均县风化淋滤型高岭土矿床赋存在与一定风化母岩岩性相依存的同一时代层位中。矿体产于寒武纪下统((?)_1)和震旦系上统灯影组(Zbdn)之间的平行不整合面上,呈断断续续的含矿带。风化母岩为寒武系下统暗色含硫有机质、硅质页岩,含矿带的下盘岩性为灰白色厚层状白云岩。 高岭土矿体呈极不规则形态产于白云岩的卡斯特溶洞中。高岭土风化壳具有明显的分带性,由上而下大体上可划分为褐铁矿(铁帽),三水铝石和明矾石残积带→砾状、团块
The weathered and leached kaolin deposits in both counties of Hubei Province exist in the same epoch of the same lithology of weathered mother rocks. The orebodies were formed on the parallel unconformities between the Lower Cambrian (Å) _1) and the Sinian Upper Protracted Zebra (Zbdn), with intermittent ore-bearing zones. The weathered mother rock is the dark Cambrian lower sulfur organic matter and siliceous shale. The footwall lithology of the ore-bearing belt is thick gray-white layered dolomite. The kaolinite orebodies are extremely irregular in the Custer caves of the dolomite. Kaolin weathering crust has obvious zonation, from top to bottom can be roughly divided into limonite (iron cap), gibbsite and alunite residual zone → gravel, clumps
