样子哨盆地北缘找矿前景

样子哨盆地北缘构造岩浆活动强烈,成矿地质条件有利。盆地北西北东向韧性剪切带叠加有后期脆性构造,带内发育有串珠状Au元素化探异常,且与已知金矿床（点）吻合较好,类比认为韧性剪切带型金矿具有良好的找矿前景;南东侧盆缘断裂表现为多期次活动叠加的特点,沿断裂带充填有含金硅化蚀变岩,应注意寻找中低温热液型金矿;盆地中早侏罗世闪长岩、花岗斑岩侵入灰岩中,在其周围相应伴随有Au、Ag、Cu、Pb、Zn、W、Mo等元素化探异常,矽卡岩型铜钼矿找矿前景较好。

Exploration prospects of north rim of Yangzishao Basin

Tectonic magmatic activity of Yangzishao Basin northern rim is strong,ore-forming geological conditions are favorable.Basin NW and NE ductile shear belts are superposed late brittle structure,and developed beaded Au elements geochemical anomalies in the belts,and agreed well with the known ore deposits（points）,the analogy considered that ductile shear zone type gold deposit has good exploration prospects.SE basin margin fault showed the features of multi- period secondary activity,along the fracture zone filled with gold-bearing silicified altered rock,should pay attention to find the medium-low temperature hydrothermal type gold deposits;In the Early-Middle Jurassic,the diorite and granite porphyry intrusive limestone,in its surrounding accompany Au,Ag,Cu,Pb,Zn,W,Mo and other elements geochemical anomalies,The exploration prospect of skarn type copper-molybdenum ore is better.
