| 中文摘要: |
| 黑山金矿“又称宝东金矿”处于沙泉子断裂以南的中天山地块，为 2016—2017年“ 1∶5万沙泉子幅矿产地质调查”新发现的金矿点，处于北西向和北东向断裂交汇部位，赋存于编号为 SHS-15岩屑测量综合异常中，对重点地段通过槽探工程结合物探高磁精测剖面和激电测深成果实施了钻探验证。认为金矿化带赋存于晚古生代中酸性火山岩组，其次为天湖岩群变质岩，受北东向构造控制，成因为浅成低温热液型。该区总体工作程度低，通过综合研究，认为黑山金矿区除新圈定的金矿化带外，还存在北区、南区 2个成矿潜力地段，目前仅对现有矿化带进行了初步验证和控制，矿区深部及两侧、南区及北区有较好找矿前景，应进一步开展地质勘查。 |
| 英文摘要: |
| Heishan (Baodong) gold deposit is located in the Middle Tianshan block to the south of Shaquanzi fault. It is a newly discovered gold deposit in the “1∶50000 mineral geological survey of shaquanzi sheet” from 2016 to 2017. It is located at the intersection of NW and NE faults and occurs in the comprehensive anomaly of cuttings measurement No.SHS-15. Combined with the results of high magnetic precision profile and IP sounding, drilling verification was carried out. It is considered that the gold mineralization belt is hosted in the late Paleozoic intermediate acid volcanic rock group, followed by the metamorphic rocks of Tianhu group, controlled by the NE trending structure and formed by epithermal type. The overall level of work in this area is low. Through comprehensive research, It is believed that there are two ore-forming potential areas in the north and south areas besides the delineated gold mineralization zone. At present, only the existing mineralization zones are preliminarily veri.ed and controlled. The deep and two sides of the mining area, the south area and the north area have a good prospect of prospecting. Therefore, further geological exploration should be carried out. |
