zonation

quartz grains can exhibit zonation and rounding.

石英砂具有显示成带和圆的特性。

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.

这些矿床可分高硫化型和低硫化型,且都具有典型的岩蚀、蚀分带等矿床特征。

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.

构造破碎带的岩石具有明显的对称分带性：破碎带的中心钠柱石矿体，向两侧依次榍石透辉石长英岩带、黑云母钠长岩带，并逐渐过岩。钠柱石矿的成因类型沿构造破碎带产出的热液交代脉型。

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.

韧性剪切带内构造岩、岩蚀分带明显,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”成矿特征。
