| 摘 要： | 新疆南部首次发现质量好的祖母绿(绿柱石),其成矿地质条件研究意义重大.本文主要对新疆南部祖母绿(绿柱石)矿的成矿地质条件进行初步探讨,包括区域地质特征、矿区及矿体地质特征、矿石显微矿物学特征等.发现新疆祖母绿矿体的形成和分布,受区内地层、岩浆、构造等多种因素和条件限制.祖母绿(绿柱石)多产于含碳质灰岩、页岩的方解石、方解石-石英细脉中,含祖母绿(绿柱石)矿脉多以斜交脉、顺层脉产出.在此研究基础上,根据所采集的样品,进行了显微矿物组合特征和生成顺序的微观矿物学研究,将成矿作用过程划分为三个期次,即成矿前、成矿期、成矿后.得出在成矿期形成的主要矿物为方解石、石英、钠长石、绿柱石等.通过上述研究,对该区祖母绿(绿柱石)找矿具有重要的指导意义.
