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型和低硫化型,且都有典型的围岩蚀变、蚀变分等矿床特征。

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.

韧性剪切内造岩、围岩蚀变分明显,并有典型的“(超)糜棱岩—英、黄铁矿、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.

造破碎的岩有明显的对称分性：破碎的中心为钠柱矿体，向两侧依次为榍透辉长英岩、黑云母钠长岩，并逐渐过渡为围岩。钠柱矿的成因类型为沿造破碎产出的热液交代脉型。
