Many types of crushed stone crushed stone is not a standardized commodity. it is made by mining one of several types of rock such as limestone, granite, trap rock, scoria, basalt, dolomite, or sandstone crushing the rock and then screening the crushed rock to sizes that are suitable for the intended end use. the intended use also dictates which types of rock should be used.
Read MoreCrushed stone the unsung mineral hero crushed stone is often looked upon as one of the lowliest of commodities, however it is used for such a wide variety of purposes in so many industries that it should be elevated to a position of distinction. it is the geologic commodity upon which almost everything is built. the wordle word cloud above shows just a few of its diversity of uses. unsung mineral hero is a quote from the late dewey kirstein, economic geologist and one of the authors early supervisors. 7
