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、蚀变分带等矿床特征。
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.
   韧性剪切带内构造岩、围岩蚀变分带明显,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。
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.
   构造破碎带的岩石具有明显的对称分带性：破碎带的中心为钠柱石矿体，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。钠柱石矿的成因类型为沿构造破碎带产出的热液交代脉型。
