Study on application of radar technique to explore mineral resources. 1. Sample test in laboratory; Radar ho no kosho tansa eno tekiyosei kento. 1. Shitsunai shiryo shiken

Abstract

Dielectric constants of ore body and mother rock specimens taken from an epithermal gold deposit were measured in the frequency band of radar technique. Applicability of the radar technique to mineral exploration has been investigated by comparing measured results and ore showing. This paper describes the results. Measured results of the dielectric constants are summarized as follows. The specific dielectric constant in the forced dry condition did not depend on specimens. The specific dielectric constant in the water saturated condition increased with increasing the porosity. The conductivity increased with increasing the specific dielectric constant. The specific dielectric constant and conductivity increased with increasing the water content. The specific dielectric constant did not depend on types of rocks. The specific dielectric constant decreased with increasing the frequency. Difference of the specific dielectric constant in the water saturated condition decreased with increasing the frequency. The radar technique was applied to blind deposits. Since they were often in the ground water saturated zones, it was considered that the reflection at the boundary was enhanced with increasing the difference of specific dielectric constant between ore body and mother rock compared with that in unsaturated zones. 8 refs., 8 figs., 3 tabs.
