Discussion on relationship of the wall rock alteration and the mineralization of gold deposit in the duhuangling gold area , eastern jilin 吉东杜荒岭金矿区围岩蚀变与金矿化关系
Em , like resistivity , can also give structural information : faults , shear or altered conductive areas 和电阻率法一样， em法也能提供构造方面的资料，如断层、剪碎带或蚀变导电带。
The altered rocks had a similar development with the hydrothermal ore deposits in the area of three paralleled rivers 蒙脱石化蚀变岩的发育分布与三江地区热液矿床的分布具有相似的规律。
Gold deposits are mainly the type of quart vein and etach rock , there are some type of porphyry and scraping rock containing charcoal 金矿以石英脉+蚀变岩型为主，也有含炭碎屑岩型和斑岩型。
Except the simmering in deep area , other three kinds of hydrothermal karst would associate and induce geological disasters 除深部相浸煮蚀变作用外，其余3种热水岩溶作用都可伴生和引起地质灾害。
Hydrothermal alteration is closely associated with gold mineralization , but different types play different roles in gold mineralization 热液蚀变与金矿化关系密切，但不同的蚀变对金矿化作用不同。
In several altered granites and gnoisses nascimento monitored swelling began almost immediately after the water was added 在nascimento观察的几块蚀变的花岗岩和片麻岩中膨胀作用是在加水之后几乎是立即就发生。
The assemblage of garnet - diopside in the silicate alteration rocks is different from that in the skarn of traditional idea 硅酸盐蚀变岩中的“石榴子石透辉石”组合与传统理解的“夕卡岩”内的相同组合名同实异。
This two reason accelerated the groundwater infiltration in the right bank slope . so , the weathering agency could have invaded deeply in the right bank slope 因此，右岸复杂岩体的成因是蚀变? ?构造? ?风化卸荷长期综合作用的结果。
Vignetting can occur due to the altered ray path , when the eyepiece ' s lenses are not large enough in diameter to allow all the rays to make it through 装饰图案可以发生是由于蚀变射线路径，当目镜的镜头是不是足够大的直径，让所有的光线，使之通过。
