淘锡坝锡矿床是近年探明储量达大型的锡矿床,是一种新的锡矿类型-隐爆层间裂隙带型。文章介绍了该矿床的地质特征和矿化特征,对矿区的构造进行了重点解剖,对构造控矿机理进行了探讨,提出火山机构及北东向断裂是矿区的控岩构造,控制了白垩纪成矿花岗岩体的侵入就位。而火山岩中大范围的隐爆层间裂隙带是良好的容矿构造,矿体赋存其中呈似层状,局部膨大形成厚达数十米的＂锡矿包＂。通过研究构造与矿化富集的内在联系,总结了该矿床的成矿规律。

Taoxiba deposit is a new type of tin deposit,a cryploexplosive interstrutified fracture belt type deposit,with its explored reserves reaching to a large-scale.Based on studying the characteristics of geology and mineralization of the deposit,this paper analyzes the structure of the ore field and discusses the structural ore-controlling mechanism.The conclusion is that the rock-controlling structure is volcanic apparatus and NNE trending fracture structure that controlled intrusion and emplacement of Cretaceous ore-forming granites.Large-scaled crypto explosive interstrutified fracture belt occurred in volcanic rocks is the best host structure,where formed ore bodies with a stratiform-like shape,and locally expanded ore bodies show a ＂tin ore-bunch shape＂ with a thickness ranging from 10 to even 100 meters.The metallogenic regularity of the deposit is summarized based on studying internal relations between structure and mineralization enrichment.
