The gold deposit is closely associated with pyritization、albitization and silicification.
萨日达拉金矿床位于伊犁板块和准噶尔板块的接合部位,严格受冰达坂韧-脆性剪切带控制,具体产出部位为韧性剪切带内次级剪切带:含矿岩石为糜棱岩、糜棱岩化岩石:矿床与黄铁矿化、钠长石化、硅化等关系密切;矿床异常Au下限为10×10-9;元素组合为Au、As、Ag、Zn。
Secondary feldspar was related to the albitization process of feldspar, the albitization of plagioclase began at the early stage of diagenesis, and the albi.
次生长石与长石的钠长石化过程有关,斜长石钠长石化始于成岩早期,而钾长石的钠长石化则需较高的成岩条件才能进行。
The albitization of the volcanic rocks of the Xiong′er Group,western Henan,was studied based on rock thin section observations and electron-probe microanalysis(EPMA).
对豫西地区熊耳群火山岩的钠长石化进行镜下观察发现:熊耳群火山岩中的长石有交代作用的痕迹,对长石的电子探针测试结果显示熊耳群中性火山岩中的长石几乎均为钠-更长石,且钠长石占绝对优势,酸性岩中均为较纯净的钠长石(~A b97),这些钠-更长石是岩石遭受普遍钠长石化的结果。
