| 中文摘要: |
| 广西大厂锡矿田亢马矿床位于大厂锡矿田东矿带南部,地质工作程度相对较低,经过对近些年深边部钻孔岩芯编录和井下巷道编录,发现亢马矿区不仅存在锡石和铁闪锌矿脉,而且还存在白钨矿、萤石、辉铋矿脉,并且在-25 m中段夕卡岩化、角岩化强烈,推测在矿区东南部-300～-500 m存在花岗岩侵入,对比大厂西部矿带铜坑、高峰等矿床,认为亢马矿区深部可能存在隐伏层状锡多金属矿脉,若本矿区获得找矿突破,将会彻底改变亢马矿资源危机的现状。 |
| 英文摘要: |
| There is relatively less exploration work in the Kangma tin deposit, which is located in southeastern part of Dachang tin ore field. Through the detailed logging of drill cores and tunnels which were conducted in recent years, cassiterite veins and iron-sphalerite veins were founded, also tungsten, fluorspar, and bismuth veins found too in Kangma tin deposit area. In addition, there is intensive alteration of skarn and hornfels in the underground 25m level, it is predicted that there is possibly presence of granite intrusive in the southeastern part in the depth of 300-500m below the surface. Comparing with Tongkeng and Gaofeng ore deposits located in the western part of Dachang ore field, it is predicted that there may be concealed layered tin poly-metallic veins in depth of Kangma tin deposit. If the prospecting breakthrough is achieved in the area, it will completely change the current status of mineral resources shortage in Kangma deposit. |
