Study on Geological Characteristics of Zhangyaoyuan Refractory Clay Deposit in Western Henan
摘要
Abstract
The refractory clay deposit is gently tilted and stratified in the Carboniferous Benxi Formation,and the orebodies are mainly composed of high-alumina clays and hard clays.Through the ore chemical analysis,microscopic characteristics and XRD analysis,the main components are monohydrate diaspore and kaolinite.The endothermic peak temperature of the ore is about 535℃ and the exothermic peak temperature is about 980℃,which is obtained by differential thermal analysis curves.It is believed that the ore-beating strata of Benxi Formation strata inherited the paleo-continental weathering crust formed since Middle Ordovician,bottomup chip by weathering crust depression crater where land filling to the upper epicontinental coastal swamp facies,formed the known as the Fe-Al layer of ore-bearing rock series,different clay layer formed by all kinds of clay minerals,the occurrence and distribution characteristics of the ore-bearing strata are mainly controlled by the ancient karst landform and weathering crust topography of the north-south tectonic fissures.关键词
