Geological Characteristics and Prospecting Potential of the Region of the Lengshuiwu Fluorite Deposit in Ningguo,Anhui Province
摘要
Abstract
In order to identify the geological characteristics of the Ningguo Lengshuiwu fluorite deposit and predict the direction for mineral exploration,the study identified one fluorite ore body within the area through drilling control,petrological identification,and chemical composition testing of samples.The ore body occurs in a vein-like form,with a length of approximately 500 meters and a depth extension of 273 meters.The ore body's attitude is 160°～180° ∠ 52°～62°.The grade of CaF2 ranges from 31.92%to 59.83%,with an average of 43.96%.The ore body is controlled by the near EW-trending fault F1.The deposit is classified as a fault-controlled,post-magmatic hydrothermal filling-type fluorite deposit.The middle member of the Cambrian Xiayangshan Formation has a solution porosity rate of 0.36 and a fracture development rate of 19 fractures/m2,which are favorable for mineralization.The fluorite ore-controlling model is characterized by a"four-in-one"pattern.Three regional fluorite mineralization prospective areas have been delineated.The typical geological characteristics and exploration directions of the Lengshuiwu fluorite deposit are summarized to provide strong guidance for the next steps in fluorite exploration and the expansion of exploration efforts for this type of deposit.关键词
