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.

这些床可分为高硫化型和低硫化型,且都具有典型的围岩蚀变、蚀变分带等床特征。

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,并具有典型的“(超)糜棱岩—英、黄铁、铁白云化—金化”等“三位一”成特征。

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，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。钠柱的成因类型为沿造破碎带产出的热液交代脉型。
