To measure the hardness of a mineral, Mohs scale is used. It is a 1-10 scale. Diamond is rated as 10 in that scale, and very harder than talc, which is rated as 1. Metal Metals are known to human kind for a very long time. There are evidences to prove about metal usage back in 6000 BC. Gold and copper were the first metals to be discovered.

Jul 22, 2022Dolomite rock is a sedimentary rock derived from limestone with a high percentage of the mineral dolomite. The two types are often indistinguishable in the field so geologists usually carry diluted hydrochloric acid to test the rocks. Limestone is strongly effervescent in acid, while dolomite reacts very weakly.

In Illinois, economic minerals are present deep underground in many places; for example, coal is mined to a depth of 1,000 feet, and oil is produced from porous rock layers, called pay zones, at depths of several thousand feet. Lead and zinc ores, fluorspar, silica sand, limestone, sand, gravel, clay, and shale are all found at shallower depths.
