1) beresitization
黄铁绢英岩
1.
ore forming hydrothermal solution constituent,ore forming temperature,hydrogen and oxygen isotope,Rb Sr isopleth,etc,it is proved to be an altered wallrock type of gold deposit appearing in beresitization vein,thus opening favorable prospects of finding gold in this area.
研究了胶东地区新发现的辉寨金矿床 ,依据围岩蚀变分带特征 ,成矿热液组分、成矿温度、氢氧同位素、Rb—Sr等时线数据等 ,该矿床为产于黄铁绢英岩中的蚀变岩型金矿床 ,由此扩大了该区找金前
2) pyritized phyllite
黄铁绢英岩化
1.
The early alterations of mineralization were the biotitization and potassium feldsparization,and mainly the pyritized phyllite and pyritized fluoritization argillization in the mineralization period,and but the carbonatization in the postore period.
成矿早期蚀变为黑云母化、钾长石化；成矿期主要是黄铁绢英岩化、黄铁萤石泥英岩化；而成岩后期则主要为碳酸盐化。
3) beresite
黄铁长英岩
5) Pyrilic phyllic alteration gold deposits controlled by shear zone in granite
受花岗岩中相关剪切带控制的黄铁绢英岩型金矿
6) sericite quartz-schist
绢云母石英片岩
1.
When we dig a tunnel in sericite quartz-schist with dobby drills,regular bending of the boreholes appears,which affects drilling speed and the borehole quality .
在绢云母石英片岩中开挖隧洞,使用多臂钻造孔爆破,出现钻孔有规律的弯曲现象,影响了钻爆速度和成洞质量。
补充资料：黄岩岛
| 黄岩岛 位于中国南海中东部。是从4000米深的海盆底部伸到海面附近的近似等腰三角形的大环礁。东西长15千米，南北宽15千米。在环礁北侧有宽约360米的缺口和南海相通，礁盘边缘有数以千计1～4平方米不等的巨大礁块突出水面0.3～3.0米。密集在环礁西北端的称黄岩，东南方者称南岩。 |
