摘要
通过对广东省小竹磷矿矿床地质特征进行综合分析研究,磷矿体产于泥盆系与寒武系不整合范围含磷粉砂质页岩中内,矿体呈层状与围岩一致,浅部较陡而深部较缓,总体延长近南北。研究认为矿床类型为沉积矿床,属滨海-浅海环境;含矿层位为中泥盆统郁江组,矿石类型只要为砾状磷块岩,其中含磷的粉砂质页岩可作为寻找磷矿层的标志。对磷矿床地质特征的研究与成因分析有利于对该类矿床的研究。
A comprehensive analysis and study of the geological characteristics of the Xiaozhu phosphate deposit in Guangdong Province is conducted and it shows that the phosphate ore body is occurred in the phosphorus-bearing silty shale of Devonian and Cambrian unconformity range,and the ore body is stratified and consistent with the surrounding rocks,steeper in the shallow part and gentler in the deep part,with an overall extension near the north and south.The type of deposit is considered to be sedimentary deposits in a coastal-shallow marine environment;the ore-bearing horizon is the Middle Devonian Yujiang Formation,and the ore type is mainly rudaceous phosphorite,in which phosphorus-bearing silty shale can be used as a marker to find phosphatic bed.The study of geological characteristics and genesis analysis of phosphate deposits is beneficial to the study of this type of deposit.
