| 中文摘要:迪木那里克铁矿带位于新疆东昆仑西段,阿尔金陆缘地块祁漫塔格古生代复合沟弧带。近年来,以迪木那里克铁矿床为重心,以1:5万航磁异常为依托,在迪木那里克铁矿床的外围取得了较好的找矿成果。在长沙沟构造蛇绿混杂岩带内,新发现了河肃铁矿床、玉岭铁矿床等一系列沉积变质型铁矿床(点),部分矿床已达中型以上规模。磁铁矿体主要赋存于复理石岩片中的千枚岩层内。可确定该铁矿带呈近EW向展布,延伸达50 km,其远景资源量可达10亿吨。在该矿带内,可利用地层、构造、围岩蚀变、航磁异常等作为找矿标志。 |

| New prospecting discoveries in Dimunalike iron deposit and its peripheral areas in East Kunlun Mountains, Xinjiang |

| Abstract:The Dimunalike iron deposit is located in western East Kunlun Mountains of Xinjiang in northern Tibetan Plateau and lies in the Qimantag Paleozoic complex trench-arc belt of Altun continental margin block. In recent years, the study was focused on the Dimunalike iron deposit on the basis of 1:50 000 aeromagnetic anomaly survey and, as a result, obtained satisfactory prospecting results in surrounding areas of the Dimunalike iron deposit. A series of sedimentary-metamorphic iron deposits were found in the Changshagou tectonic ophiolitic complex belt, such as the Hesu iron deposit and the Yuling iron deposit, with some of them reaching the medium size reserves. The magnetite bodies are mainly existent in the phyllite of flysch slice, and these deposits have nearly east-west extension of 50 km and have 1000 million tons of prospective resources. Factors such as stratigraphy, tectonics, alteration and aeromagnetic anomalies can provide valuable ore-prospecting clues to ore-prospecting work. |
