塔里木地台北缘深断裂两侧有多处碱性杂岩体分布。通过对其长约2000km范围内地质资料的搜集,实地地质调查,遥感资料解译,航、地磁异常资料的分析与实测工作、重点评价区工程验证等一系列成果的综合分析与研究,发现260km铁磷矿化带,控矿岩体具有“串珠状等距性特征,铁磷矿体主要赋存在辉石岩和黑云母辉石岩中。”在三个调查区中划分出9个找矿远景区。尉犁--兴地调查区中发现多处偏碱性超基性杂岩体,其中三处远景区经深部验证均发现铁磷矿体。是寻找内生磷矿颇具找矿前景的地区。温宿-拜城调查区是寻找Nb-Ta-P矿前景的最佳地段。巴楚--阿图什调查区应是寻找碳酸盐型磷-稀土矿的有利地区。经研究提出:“古老地台边缘受深大断裂控制的偏碱性-超基性杂岩成矿,碱幔分异-碱性偏碱性不混熔岩浆成矿-熔离作用形成层状铁磷矿体的成岩成矿模式”。
There are several alkaline complexes distributed on both sides of the deep fault on the northern edge of Tarim platform. Through the comprehensive analysis and research of a series of achievements such as the collection of geological data over a length of 2000km, the field geological survey, the interpretation of remote sensing data, the analysis and measurement of anomalous anomalies of aeronautic and geomagnetic anomalies, and the verification of key evaluation areas, a total of 260km Iron-phosphate mineralization belt and ore-controlling rock mass have beaded equidistant characteristics, and the iron-phosphorus ore bodies are mainly found in pyroxenite and biotite pyroxenite. “In the three survey areas, 9 Prospecting prospect area. Yuli - Several alluvial ultrabasic complex bodies were found in the Hixi survey area, of which three iron ore bodies were found by deep verification. Is looking for endogenous phosphate ore prospecting area quite. Wensu - Baicheng investigation area is looking for the best prospect of Nb-Ta-P prospect. The Bachu-Assush survey area should be a favorable area for finding carbonate-type phosphorus-rare earth minerals. According to the research, it is suggested that the mineralization of alkaline-ultrabasic complex controlled by deep-large faults on the edge of ancient platform and the differentiation of alkali-mantle and mantle-alkaline alkaline-alkaline non-mixed magmatic mineralization- Diagenetic metallogenic model of iron phosphate ore body ”.
