zonation

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.

这些矿床可分为高硫化和低硫化,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、铁矿、铁白云化—金矿化”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、黑云母钠长岩带，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。
