| 中文摘要: |
| 内蒙古达斯呼都格矿区位于得尔布干成矿带西南段，区内以斑岩型矿床为主，使用近红外光谱矿物分析技术在矿区内进行蚀变矿物填图，通过对区内17个钻孔862个样品进行测量，分析表明主要蚀变矿物有伊利石、蒙脱石、绿泥石、绿帘石、高岭石、地开石、石膏、石英、碳酸盐等，石英脉多以0.1-1cm宽度的细脉形式出现。蚀变分带明显，热液活动强烈，总体上显示了从东南部向西北部热液温度逐渐增高的趋势，为铜矿勘查工作部署提供了可靠的地质依据。 |
| 英文摘要: |
| The Dasi mineralizing area of Inner Mongolia is located in the southwest of the Derbugan metalloginic belt. Porphyry-type deposits are dominant this area. Alternation mineral mapping was conducted using the near infrared spectroscopy technology. Measurement of 862 rock samples from 17 drill borholes shows the alternation minerals include illite, montmorillonite, chlorite, epidote, kaolinite, dickite, gupsum, quartz, carbonate and so forth. The widths of quartz veins are mostly 0.1-1cm. The alternation minerals appear in zones obviously indicative of intense hydrothermal activity. Overall, the hydrothermal temperature tends to increase gradually from southeast to northwest. These observations provide reliable geologic evidence for deployment of copper exploration. |
