Abstract
The data on dielectric properties of Indian rock samples are very sparsely reported in the literature. Keeping this in view, we have carried out laboratory measurements of the dielectric constant and loss tangents of some samples of sandstone, quartzite, limestone, marble, dolerite and basalt. LCR bridge and Q-meter have been employed for measurements in the frequency range 10 - 10' Hz. The results have been presented in the form of variation of these parameters with frequency which show characteristic features. Observations on the effect of moisture content of these samples on the dielectric properties have also been reported. Further, correlation of petrographic studies of rock samples with measured variations of dielectric properties has been attempted.
Highlights
The laboratory measurements of electrical properties of earth's forming rocks and minerals have played an important role in developing electrical and electromagnetic prospecting method of mineral exploration (Keller and Frischknecht, 1966; Madden and Cantwell, 1967; Von Voorhis et al, 1973); in crustal sounding (Hermance, 1973); in lunar and planetary sounding (Banks, 1969; Brown, 1972; Dyal and Parkin, 1972) and in glacier sounding (Rossiter et al, 1973)
In view of the growing importance of laboratory measurements of electrical properties and keeping in view the scarcity of such data on Indian rocks, we have carried out measurement of dielectric constant and loss tangent of some Indian rock samples in the radio wave frequency range f r o m 102 - 107 Hz using LCR bridge and Q-meter
We have reported the results of measurements of dielectric constant and loss tangent of two samples of sandstone, and one sample each of quartzites, marble, limestone, dolerite and basalt
Summary
The laboratory measurements of electrical properties of earth's forming rocks and minerals have played an important role in developing electrical and electromagnetic prospecting method of mineral exploration (Keller and Frischknecht, 1966; Madden and Cantwell, 1967; Von Voorhis et al, 1973); in crustal sounding (Hermance, 1973); in lunar and planetary sounding (Banks, 1969; Brown, 1972; Dyal and Parkin, 1972) and in glacier sounding (Rossiter et al, 1973). We have reported the results of measurements of dielectric constant and loss tangent of two samples of sandstone, and one sample each of quartzites, marble, limestone, dolerite and basalt. Dielectric constant and loss tangent measurements on various rock samples have been carried out.
