广东东源鹿湖嶂锡铁矿床成因及找矿标志

Deposit origin and prospecting indications for Luhuzhang stannum-iron deposit in Dongyuan County,Guangdong Province

系统研究了鹿湖嶂矿区的地质背景以及岩浆活动造成区域变质作用对矿床成因影响,论述矿区的控矿因素及围岩蚀变,并对该矿床成因做了探讨,认为鹿湖嶂矿区锡铁的成矿作用,与中生界三叠系上统大顶群、大顶第3层钙铁质泥板岩、燕山三期黑云母花岗岩有密切的联系.并从地质角度和物探手段对矿区的找矿标志进行了阐述.

The geological background of the Luhuzhang deposit was extensively investigated, and the effects of the geological degeneration of the mine area due to the magma activities on the deposit formation were discussed in the paper. It was shown that the mineralization of the Luhuzhang stannum-iron deposit was closely related to the Triassic series upper Dading group of the Mesozoic Era, the calcium-iron shale in the Darling third stratum, and the biotite granite of the Yanshan third period. The prospecting indications based on geological and physical surveys were described as well.
