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.
这些矿床可分为高和低,且都具有典围蚀、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.
构造破碎带具有明显对称分带性:破碎带中心为钠柱矿体,向两侧依次为榍透辉长英带、黑云母钠长带,并逐渐过渡为围。钠柱矿成因类为沿构造破碎带产出热液交代脉。
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、围蚀分带明显,并具有典“(超)糜棱—英、黄铁矿、铁白云—金矿”等“三位一体”成矿特征。
