Radioactive characteristics and prospecting significance of fluorite deposits in Southern Song County of Western Henan Province
China is the largest consumer of fluorite in the world.With the rapid development of aerospace,semiconductor,communication and other fields,the consumption and price of fluorite are on the rise by years,and its scarcity and strategic importance are increasingly improving.In recent years,the exploration and development efforts of fluorite mine have also enhanced,however,at present,the exploration of fluorite mine mainly makes use of these methods,which are like mapping and engineering etc.This research,selected four representative fluorite deposits in the southern part of Song County as experimental subjects,utilized the gamma ray spectrometers to measure the radioactivity of different types of rocks,identified and studied the radioactive characteristics of fluorite deposits,and then,delineates the zones(points)of radioactive anomalies.It can provide new ideas and methods for the exploration of fluorite deposits of the same type.The results show that the γ-ray radiation intensity data that has different types of rocks,ranges from 5.54 to 68.54;The content of elements U,Th,K,and Tc(total ele-ment)respectively range from 3.1×10-6 to 30.1×10-6,12.1×10-6 to 90.1×10-6,0.1%to 8.7%,and 13.0×10-6 to 99.3×10-6.Research thinks that there is the regularity in the radioactive characteristics among different types of fluorite ores.As follows,there is a good consistency between the location of radioactive anomaly zones(points)and fluorite ores,the radiation intensity of the fluorite ore body is characterized by the low data anomalies compared to the surrounding rock,and Th element anomaly is the most stable.Therefore,measuring the differ-ences in radioactive characteristics of the different types of rocks can effectively find out the information of the loca-tion of fluorite ore body,which provides some new work ideas and methods for fluorite ore exploration.
