粤北太渡垅-苦竹坪地区Y矿床地质特征及找矿标志

Geological Characteristics and Prospecting Indicators of Y Deposit in Taidulong-Kuzhuping Area,Northern Guangdon

粤北太渡垅-苦竹坪Y矿位于长江Y矿田和百顺Y矿田的结合部位,岩浆活动强烈,构造发育,热液活动叠加,具有良好的找矿前景。Y矿体产于硅化碎裂岩和花岗碎裂岩的裂隙中,严格受断裂构造控制,为与硅化断裂带有关的中低温热液矿床。繁杂岩体中穿插的白垩纪小岩体和基性脉岩、不同断裂构造的交汇部位和岩石蚀变标志(硅化、赤铁矿化和褐铁矿化等)为重要的找矿标志。

Taidulong-Kuzhuping Y ore deposit in northern Guangdong is located at the junction of the Yangtze River Y ore field and Baishun Y ore field.The area is characterized by intense magmatic activity,developed structures,and superimposed hydrothermal activity,indicating a promising prospecting.Y ore body occurs in the fissures of silicified cataclasite and granitic cataclasite,is strictly controlled by fault structure,and is a medium-low temperature hydrothermal deposit associated with silicified fault zone.Small Cretaceous rock masses and basic dike rocks interspersed in complex rock masses,and the junction of different fault structures and rock alteration indicators(silicification,hematitization and limonitization,etc.)are important prospecting indicators.
