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
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。
Igneous topazites found recently in South China are closely associated with F-rich granites in time and space.
新近在华南发现的黄英岩与富氟花岗岩存在密切的时空联系。
