| 摘 要： | 本文对成矿带内的岩浆岩杂岩体进行了含矿性研究,划分出4个含矿杂岩带与5个矿床成因类型。成矿专属性研究表明:岩浆岩型铁磷矿受古地台边缘深大断裂控制;容矿岩石为主要偏碱性-铁质及铁镁质岩系列;容矿岩石主微量元素明显不和谐;岩石类型共生组合主要表现为黑云母透辉石岩、辉石岩、碱性辉长岩、斜长岩、碳酸岩的共伴生;矿物共生组合主要表现为透辉石+磷灰石+磁铁矿+黑云母,斜长石+磷灰石+磁铁矿+钠黝帘石组合,辉石+磷灰石+磁铁矿等特征;元素的共生组合主要表现为P、Fe、Ti、V、REE具显著相关性。通过预测研究,进行了找矿远景区的划分,划分出具有成矿条件的9个找矿远景区。

| Abstract: | This paper deals with the mineral-bearing characteristics of magmatite complex rocks in the Tianshan metallogenic belt.4 mineral-bearing complex rock belts and 5 deposit genetic types have been determined.The research on metallogenic specialization shows the following characteristics: 1) Magmatite iron phosphate is controlled by the deep fracture at the edge of the platform;2) The host rock is mainly of the alkaline ferruginous-mafic rocks suite;3) The major and trace elements in host rack are obviously inconsistent with each other;4) The paragenesis of rock types mainly shows the association relationships of biotite diopsidite,pyroxenite,alkaline gabbro,plagioclase and carbonate rock;5) Mineral paragenesis mainly shows the characteristics of diopside + apatite + magnetite + biotite,plagioclase + apatite + magnetite + soda-zoisite and pyroxene + apatite + magnetite.The elements paregenesis shows notable correlation of P,Fe,Ti,V and REE.Based on prognostic research,the authors delineated 9 ore perspective areas with ore-forming conditions. |
