摘要/Abstract

摘要： 西藏甲玛铜多金属矿床位于青藏高原冈底斯成矿带内，以其矿石品位高、规模大、矿种多的特点成为冈底斯带内为数不多的超大型斑岩-矽卡岩型矿床。通过对甲玛矿床走向、倾向方向上不同边界品位条件下铜平均品位与铜金属量的研究表明：甲玛矿床铜的矿化富集的规律性在矿体倾向上明显优于走向上，矿体在倾向上的规律性变化特征，与岩浆成矿作用有关矿床典型的矿石分带性是一致的。同时，铜的矿化富集规律将对深部找矿以及矿山采矿都有着重要的指示意义和实用性。

Abstract: The Jiama polymetallic copper deposit locates in Gangdese metallogenic belt.Due to its high grade, large scale and variety of types, it becomes one of rare ultra-large porphyry-skarn type deposits in Gangdese belt.According to research on the copper's average grade and the metal quantity under the different cut-off grade in strike and dip of ore-body, it is showed that the copper mineralization enrichment regularity in Jiama deposit is better than what is in the direction of their strike, and the regularity in the direction of their dip is consistent with the typical mineral zoning of magmatic mineralization.At the same time, the copper mineralization enrichment regularity has a significant indication and practicality to the prospecting and exploration of deep mine.

Key words: Porphyry-skarn type deposit, The regularity of mineralization enrichment, Gangdese metallogenic belt
