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,且都具有典型围岩蚀变、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.

韧剪切带内造岩、围岩蚀变分带明显,并具有典型“(超)糜棱岩—石英、黄铁矿、铁白云石化—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.

造带岩石具有明显对称分带：带中心为钠柱石矿体，向两侧依次为榍石透辉石长英岩带、黑云母钠长岩带，并逐渐过渡为围岩。钠柱石矿成因类型为沿造带产出热液交代脉型。
