zonation

1.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.

这些矿床可为高硫化型和低硫化型,且都具有典型的围岩蚀、蚀等矿床。

2.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.

性剪切内造岩、围岩蚀明显,并具有典型的“(超)糜棱岩—石英、黄铁矿、铁白云石化—金矿化”等“三位一体”成矿。

3.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.

造破碎的岩石具有明显的对称性：破碎的中心为钠柱石矿体，向两侧依次为榍石透辉石长英岩、黑云母钠长岩，并逐渐过渡为围岩。钠柱石矿的成因类型为沿造破碎产出的热液交代脉型。
