| 摘 要： | 本文通过工程勘查资料及岩石化学特征分析，从构造-岩浆-流体系统来解析汤家坪钼矿的成矿地质特征，为相似地质条件下的深部找矿提供思路。研究表明，早白垩世，在大别造山带核部，陆内张性构造环境中，沿深大断裂的岩浆上侵，成就了具有明显成矿地质特征的汤家坪钼矿：穹隆状容矿空间——矿体岩体内矿化元素呈晕律层状分布。

| Abstract: | The geological characteristics of Tangjiaping molybdenum deposit is investigated through engineering exploration and chemical analysis and explained by structure - magma - fluid system theory, which can provide experiences for the prospecting in the similar distract. The available data shows that the ore - forming fluid is separating from granite porphyry magma which intruded along discordogenic fault in core of Dabie orogenic belt in the extension environment in early Cretaceous. The geological characteristics shows that Tangjiaping molybdenum deposit is a special one which is composing of bosslike ore host space with regularity sill like distribution of ore - forming elements. |
