They can be divided into low sulphidation and high sulphidation types,with typical wall rock altera tion and alteration zonation of epit hermal de-posit.
这些矿床可分为高和低,且都具有典的围岩蚀变、蚀变分带等矿床特征。

这些矿床可分为高和低,且都具有典的围岩蚀变、蚀变分带等矿床特征。
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.
韧性剪切带内造岩、围岩蚀变分带明显,并具有典的“(超)糜棱岩—英、黄铁矿、铁—金矿”等“三位一体”成矿特征。
There is an obvious rock zonation from the middle to bothsides of the structural shatter zone, generally from marialite orebody through diopside-felsite,biotite-albitite to the host Proterozoic rocks.
造破碎带的岩具有明显的对称分带性:破碎带的中心为钠柱矿体,向两侧依次为榍透辉长英岩带、黑母钠长岩带,并逐渐过渡为围岩。钠柱矿的成因类为沿造破碎带产出的热液交代脉。
