摘　　要：以往对峨眉山玄武岩同源的浅成或边缘相岩体如细粒辉长岩体、辉绿岩体、辉绿辉长岩体是否能够达到纤维用玄武岩用矿标准进行评价极少,本文在野外地质调查的基础上,对四川米易县棕树湾辉长岩体开展了岩石类型以及原材料化学成分分析。研究表明白马矿区外围棕树湾辉长岩体分异良好,更易形成低铁低钛韵律层,因此上部其上部韵律层或后期浅成辉长岩体符合拉丝条件,可为下步找矿提供参考。In the past,it is rare to evaluate whether the Emeishan basalt homologous shallow or marginal rocks,such as fine gabbro,diabase and diabase,can meet the ore use standard of fiber basalts.This paper is based on the field geological survey.In this paper,the rock types and chemical composition of raw materials of palm Shuwan gabbro in Miyi County,Sichuan Province were analyzed.The results show that the Pangshuwan gabbro in the periphery of Baima mining area has good differentiation and is more likely to form low iron and low titanium rhythmic layer,so the upper rhythmic layer or the later shallow gabbro body accords with the wire drawing condition and provide reference for the next step of prospecting.
