Feldspar Dissolution and Its Influence on Reservoirs: A ...

Etymology. The name feldspar derives from the German Feldspat, a compound of the words Feld ("field") and Spat ("flake"). Spat had long been used as the word for "a rock easily cleaved into flakes"; Feldspat was introduced in the 18th century as a more specific term, referring perhaps to its common occurrence in rocks found in fields (Urban Brückmann, 1783) or to its occurrence as "fields ...

grain density is the density based solely on the solid material, excluding the pore space. Bulk density is impor-tant for calculation of gravity anomalies, and grain density is used for studying systematic trends in density as a function of rock composition. We can also calculate the porosity, P=1 (r bulk/r grain). The bulk volume is measured by
