| 中文摘要: |
| 硝尔库勒大型锑矿是在最近1:5万区域地质矿产调查中发现的，经过进一步的普查工作，已查明（333）＋（334）类锑金属资源量达20.36万吨，平均品位8.90%，其规模居昆仑－秦岭锑成矿带之首，是近年来西昆仑地区找矿的重大突破。矿床赋存于中二叠统黄羊岭组二段（P2h2）碎屑岩中，受NE向层间破碎带控制。矿体呈脉状、似层状、透镜状产出，在走向和倾向上均呈舒缓波状延伸，具尖灭再现、膨大狭缩、分支复合特征。矿石矿物主要为辉锑矿，次为少量黄铁矿，共生矿物为少量雄黄和雌黄，次生矿物为少量锑华，脉石矿物主要为石英，次为长石、方解石等。矿石自然类型主要为硫化矿石，其工业类型为单一锑矿石，矿床成因上属层控构造改造型低温热液矿床。硝尔库勒锑矿的发现，进一步说明了西昆仑矿集区具有相应层位寻找锑矿的巨大潜力。 |

| The Xiaoerkule antimony deposit was found in the 1:50 000 regional geological and mineral surveys recently. After the further work, 2.036 million tons of antimony resources by the type of (333)+(334) with a geologic average grade of 8.90% were proved. The dimension of the deposit is ranked first in the Kunlun-Qinling Sb metallogenic belt, meaning a significant breakthrough of West Kunlun in recent years. This deposit occurs in the clastic rocks of the second section of Huangyangling Formation（P2h2）in the Middle Permian, and is controlled by the NE trending interlayer fault zone. The ore bodies exhibit shapes of vein, stratoid and lenticular. Extension in the direction of strike and inclination both show slightly wavelike. The ore bodies have the characteristics of end to end alignment, expansion and shrinkage, and branch recombination. The main ore mineral is antimonite, secondly is pyrite, and paragenous minerals are realgar and orpiment, secondary mineral is antimony bloom. The main gangue minerals are quartz, feldspar, calcite and so on. Main natural type of the ores is vulcanized type, and the industrial type of the ores is single antimony ore type. The genesis of this deposit belongs to a reformed strata bound type of epithermal deposit. The discovery of Xiaoerkule Sb deposit demonstrates further that there has a huge potential to find out antimony ore in the corresponding horizon in the West Kunlun ore-concentrating area. |
