| 摘 要： | CHIM法自提出以来,一直在进行着不断的改进,但依然存在缺陷,主要表现在设备笨重、操作复杂、成本高、工作效率低,且大多数情况下只提取阳离子态的金属元素.在新的成晕理论的指导下,通过在已知矿区进行低电压(9V干电池)偶极子供电方式下的阴极提取实验,证实其方法有效性的基础上,考虑到阴离子和阳离子都可以提供找矿有用信息的条件下,首次提出了低电压(9V干电池)偶极子供电方式下的"偶极"提取法,并在山东招远尹格庄金矿和新疆210金矿进行了实验研究,结果表明,在已知矿体上方阴离子态元素异常也很发育,将阴离子异常与阳离子异常累加,可清晰地反映深部隐伏矿体的赋存位置.该改进的方法轻便、成本较低,可同时提取阴离子和阳离子态的金属元素,所获信息量大、提取率高,在野外工作方式灵活,适合于野外地质勘查和科研工作. |

| Abstract: | CHIM has been constantly improved since it was proposed,but there are still many disadvantages.Main disadvantages of the current CHIM reduce its value as an exploration tool.The previous CHIM has heavy equipment,complicated operation procedures,high cost and low working efficiency,and in most cases only positively charged mobile forms are collected.With the new halo-formation theory,tests of extract in the cathode electrified by low voltage "dipole" was carried out at known mine areas,and their feasibility and availability were verified.According to anionic as well as cationic species may provide useful information,"dipole" CHIM electrified by low voltage dipole was firstly proposed,and field tests of this improved technique have enabled identification of distinct multi-element anomalies at Yingezhuang gold deposit in Shandong and at 210 gold deposit in Xinjiang.The test data indicated that anionic species anomalies of elements are very obvious above the existing ore bodies,and the sum of anionic species anomalies of elements and cationic species anomalies of elements enables identification of the position of the deeply buried ore body. The improved CHIM has simple equipment,convenient operation procedures,low cost and enables simultaneous extraction of anionic and cationic species of elements.Thus,much useful information can be obtained,and the rate of extraction is high.So it can be applied at geological survey and researches. |
