放射性物探方法在辽宁团山子地区金矿找矿中的应用

APPLCATON OF RADIOMETRIC METHOD IN THE PROSPECTING FOR GOLD DEPOSITS IN TUANSHANZI AREA,LIAONING PROVINCE

辽宁省兴城市团山子地区位于青龙-葫芦岛近东西向断裂的东段,碱厂岩体南缘,八家子-杨家杖子多金属成矿区的中南部.通过钻探证实,金矿化受近东西向断裂构造控制,矿化类型为碎裂蚀变岩型,具有低品位、大矿量特点,在辽西地区属首次发现.为加强对本区控矿构造特征和金矿化赋存规律的研究,采用了放射性物探方法进行探索,取得了较好的找矿效果.由于该方法简便易行,对于在区域上寻找该类型金矿具有重要意义,值得借鉴和推广。

Tuanshanzi area in Xingcheng City,Liaoning Province is tectonically located in the east section of the near E-W-trending Qinlong-Huludao fault, on the south margin of Jianchang intrusive rock body and in the Central south of Bajiazi-Yangjiazhangzi polymetallic metallogenic province. Gold mineralization is controlled by the near E-W-trending fault. The metallogenesis belongs to cataclastic altered rock type, with characteristics of low grade and large amount of ore,which is the first discovery in western Liaoning. For further research on the ore-controlling structure and the distribution of gold mineralization in the area, the radiometric method is adopted in the prospecting and has achieved good results. Because it is simple and easy to be used, the method is significant in the searching of this type of gold deposits in the area and worth to popularize.
