wall rock alteration

Recognization of two types of wall rock alteration related to porphyrite iron ore deposits

与玢岩铁矿有关的两类蚀变再认识

In the ductile shear belt, the alteration and zonation of tectonite and wall rock are obviously, and miliolite belt, quartz, iron pyrite, ankerite alteration belt and gold mineralization belt are trinity.

韧性剪切带内构造岩、围岩蚀变分带明显，并具有典型的（超）糜棱岩石英、黄铁矿、铁白云石化金矿化等三位一体成矿特征。

The wall rock alteration shows gold deposit is related the deep magmatic intrusion.

围岩蚀变表明与深部岩浆侵入作用有关.

Exploration markers includes hot-water sedimentary rocks, gossan wall-rock alteration, and geophysical and geochemical anomalies.

找矿标志主要有热水沉积岩 、 铁帽、围岩蚀变 、 地球物理异常、地球化学异常等.

The wall rock alteration is weak, with characteristics of medium-low T hydrothermal ore deposit.

围岩蚀变微弱, 具中低温热液矿床的特征.

The wall-rock alteration is complex, and the line between orebody and wall-rock is obvious.

围岩蚀变复杂, 矿体与围岩界线明显.

The wall rock alteration consists of 4 zoning, from deep to shallow, potassic zone, sericitization zone, propylitization zone and argillization zone.

围岩蚀变组合分带自深到浅依次为：钾化带、绢云母化带、青磐岩化带、泥化带，矿化主要赋存在钾化带和绢云母化带中。
