个旧矿区是一个与花岗岩有关的特大型锡多金属矿集区。近年来在花岗岩体内发现了蚀变花岗岩锡多金属矿体，进一步拓展了找矿的空间。笔者在分析个旧老厂矿田西部凹陷带花岗岩锡多金属矿床地质特征的基础上，着重从花岗岩体表层原生破裂构造对矿床的控矿规律进行了探讨。
箇舊礦區是一箇與花崗巖有關的特大型錫多金屬礦集區。近年來在花崗巖體內髮現瞭蝕變花崗巖錫多金屬礦體，進一步拓展瞭找礦的空間。筆者在分析箇舊老廠礦田西部凹陷帶花崗巖錫多金屬礦床地質特徵的基礎上，著重從花崗巖體錶層原生破裂構造對礦床的控礦規律進行瞭探討。

Gejiu mining area is an oversized tin polymetallic ore concentration area which is related with gran-ite.In recent years altered granite tin polymetallic ore bodies are found in the granite rock bodies,and it changes the future works of prospecting in this area.Based on the analysis on geological characteristics of granite type tin polymetallic deposit in hollow zones of western Laochang ore field of Gejiu,this article focu-ses on the regularities of ore controlling effect of primary crush structure on the surface of granite rock bodies over deposits.
