The detailed survey in 1997 indicated that it is a new type of PGE prospect related to crystoexplosion amphibolite.
作者于1997年在该矿点发现了与(隐爆)角闪岩有关的铂族矿化,初步认为是一个找矿前景较好的铂族矿化新类型。
In this study, Ar-Ar isotope dating of muscovite, hornblende and phlogopite was carried out in order to con.
文章以金云母、角闪石和白云母为测试对象,利用40Ar/39Ar同位素定年的方法,精确厘定了芙蓉超大型锡矿床的形成时间。
To gain a better understanding of the age of gold mineralization and its relationship with the evolution of the ductile shear zone,40Ar/39Ar plateau age analysis was made on biotitefrom biotite-quartz gneiss and on hornblende from biotite-hornblende mylonite.
对采自十八顷毫金矿区的黑云母、角闪石用阶段升温法进行40Ar/39Ar年龄谱研究,结合矿区地质特征,认为黑云母近似直线年龄谱的坪年龄(277Ma)及角闪石稳定坪年龄(288Ma)代表了韧性剪切带最新活动的时代;角闪石矿物年龄谱反映的后期热扰动(268Ma)反映区域退化变质作用发生的时代,269~277Ma的年龄可能代表了与退化变质同时的金矿化时代。
Based on the characteristics of hornblendes, we classified the alkali granitoids as two types.
