在美国怀俄明州提敦县提郭国家森林区化探圈定的已知含金砂矿地区作了磁法和电阻率测量。在布法罗河与斯内克河支流流经地的调查区,磁法成功地圈出了磁性矿物富集带。电阻率测深有效地测定了含砂砾层的厚度。土样磁化率测定则有助于区分地表磁性矿物富集引起的磁异常与深部富集引起的磁异常。 在怀俄明州提敦县提敦国家森林区的四个地区进行磁法和电阻率法调查;(见图1)。
Magnetometry and resistivity measurements were made in the known gold-bearing placer areas delineated by the Tiaokou National Forest Area Titan County, Wyoming. In the survey area where the tributaries of the Buffalo and Snake rivers pass, the magnetic method successfully excavated the magnetic mineral enrichment zone. Resistivity sounding effectively measures the thickness of gravel-bearing layers. The determination of soil magnetic susceptibility helps to distinguish the magnetic anomalies caused by enrichment of surface magnetic minerals and the magnetic anomalies caused by deep enrichment. Magnetic and resistivity surveys were conducted in four areas of the State Forest, Staten Island, in the State of Wyoming, (see Figure 1).
