4.4 Electrical conductivity of minerals and rocks
The dependence of resistivity of different groups of rocks on their mineral and chemical composition and on their structure under conditions of high temperature and pressure is analyzed. Finally, basic trends are indicated of interest for geophysics and for the use of experimental data on electrical properties of minerals.get price

C1: Electrical resistivity of different soil and rock types
2006-2-1 semi conduction occurs in minerals such as sulphides. Here the charge carriers are electrons, ions or holes. Compared to metals, the mobility and number of charge carriers are lower, and thus the resistivity is higher (typically 10-3 to 10-5 ohm-m). This type of conduction occurs in igneous rocks and usually shows a temperatureget price

The Lowdown on Low-Resistivity Pay Schlumberger
2018-12-6 resistivity pay was, practically speaking, a contradiction in terms. Their pioneering research hinged on the principle that gas- or oil-filled rocks have a higher resistivity than water-filled rocks. Through the years, how-ever, low-resistivity pay has become recog-nized as a worldwide phenomenon, occur-ring in basins from the North Sea andget price

2011-10-21 Resistivity can also be lowered by the presence of electrically conductive clay minerals, graphitic carbon, and metallic mineralization. It is common, for example, for altered volcanic rocks to contain replacement minerals that have resistivities ten times lower than those of the surrounding rocks (Nelson and Anderson, 1992).

Resistivity values relate to geology, and both resistive and conductive rocks are identified with this method. Rock porosity, pore fluids and the presence of metallic sulfides determine the values. An anomalous conductive feature seen on the modeled CSAMT data from the Taxco survey is associated with metallic luster, pyrite-like mineralization.get price

rock Definition, Characteristics, Classification, Types
Igneous rocks are those that solidify from magma, a molten mixture of rock-forming minerals and usually volatiles such as gases and steam.Since their constituent minerals are crystallized from molten material, igneous rocks are formed at high temperatures. They originate from processes deep within the Earth—typically at depths of about 50 to 200 kilometres (30 to 120 miles)—in the mid- toget price

Down-hole Geophysics in Mineral Exporation
2019-10-17 Resistivity. The opposite or inverse of conductivity is resistivity. Resistive rocks conduct electricity poorly. Silicate minerals, like quartz, are highly resistive, so have low electrical conductivity. Identifying rocks that don’t conduct electrical current can be just as important and the ones that do.get price
