摘　　要：西乡县北部饰面用花岗岩矿处于扬子板块北缘,龙门—大巴台缘褶带,区内大面积出露基性—酸性花岗岩体。饰面用花岗岩矿体由未风化层状辉斑橄榄苏长岩、中粒苏长岩、中粒角闪辉长岩矿组成,矿石呈球体形态。本文对该矿体地质特征及开采利用前景予以探讨。The granite deposit in the north of Xixiang county is located in the north margin of Yangtze plate, the Longmen-Dabaplatform margin fold belt, where a large area of basic-acid granite bodies are exposed. The granitic ore deposit lies in the rock mass,which is formed by differentiation, composed of the unweathered lamellar olives norite, the medium grained norite and the mediumhornblende gabbro, and the ore is spheroid. Based on the mining, processing and marketing of the existing mines, the geological featuresof the deposits, the development plan and the construction of green environmental mines are more deeply understood. The geologicalcharacteristics and exploitation prospect of granite in the northern of Xixiang county are discussed in this article.
