Electrical conductivity of minerals and rocks
Most metallic ore minerals are electronic semiconductors charge is carried by electrons but by electrons which are normally fixed in the atomic lattice and can be displaced by a field large enough to move them out of a rest position (leaving a 'hole') into an adjacent hole. Their resistivities are lower than those of metals and highly variable because the substitution of .
WhatsAppThe Density of Common Rocks and Minerals
· Some of the heaviest metallic minerals, like iridium and platinum, can have densities as high as 20. Rock Densities Rock density is very sensitive to the minerals that compose a particular rock type. Sedimentary rocks (and granite), which are rich in quartz and feldspar, tend to be less dense than volcanic rocks.
