| 中文摘要: |
| 在金矿脉中,金主要分布于石英脉及硫化物中,而超微细金确具有很强的活性,能够以络合物、吸附态等方式被黏土矿物或有机质捕获。矿脉的上部,多种方式运移上升的金,在次生土壤中富集形成元素异常。通过氧化-络合的方式制作的活动态提取剂,可获得稳定的可溶性络合物,采用iCAPQ数据测量。在实际应用中,通过采集B层土壤并处理加工,获得的Au元素峰值达105×10-9。圈定的靶区位于异常带延长方向上,符合矿区成矿规律,采信度高。金活动态测量适用于特殊景观区的勘查科研工作。 |
| 英文摘要: |
| Gold is mainly found in quartz vein and sulfide of gold vein, however, the super fine gold having strong activity can be captured by clay minerals or organic matter in the form of complexes, adsorption states, etc. In upper part of the vein, gold can ascending in a variety of ways and is enriched in the secondary soil to form an elemental anomaly. An active extractant prepared by oxidation-complexation can obtain stable soluble complexes which can be measured by iCAPQ. In practical application, by collecting and processing B-layer soil, the peak value of active Au can reach to 105×10-9, 10 times of enrichment degree. The delineated target area is located in the extension direction of the abnormal belt, according with the met allogenic law of the mining area and having high mining reliability. Gold activity survey is suitable for exploration and scientific research in special landscape areas. |
