【摘要】 <正>玲珑金矿是我国著名的石英脉型金矿。矿田构造以断裂发育为特征。断裂构造具多期活动,其走向以北东东向为主,次为北北东和北东向,倾向北西,倾角40°—80°。区内含金石英脉和各种脉岩严格受断裂构造控制,有规律地分布于玲珑花岗岩中。 矿区中基性脉岩发育,其岩石类型及含金量已见诸报道,本文以玲珑西山矿床为主,初步探讨中基性脉岩与矿化的关系及其预测找矿意义。更多还原

【Abstract】 The intermediate-basic dykes in the ore field can be divided into three classes, microcrystal diorite, lamprophyre and diabase . They are distributed widely. It is apparent that they increase in number and in thickness with depth from west to east.According to the distribution feature of the intermediate-basic dykes, their relation to gold-bearing quartz veins in space and time, similarity in development intensity and conformity in control structure, the close relation between intermediate-basic dykes and mineralization is dealt with. Based on the characters of sulfur-isotope composition, gold content of dykes and R-type factor analysis of microelements in ore and dykes, their genetic relation is further discussed, which has provided the important indicator for minerogenetic prognosis in depth in the ore field更多还原
