Rock forming minerals are the mineral that form the bulk of the earths rocks Most people tend to lump minerals in with rocks and have no idea that ROCKS are classified and named based on the percentage of the types of minerals they contain
The porosity of a propylitized granite from Charroux France with no fractures or sealed fractures inreases by more than four times from the unaltered % to the altered rock % This evolution results from several local porosity modifications which occur at different scales in the rock 1 at the core scale from 10 to 10 m where rock porosity changes as a function of rock forming
