Hornblende is a group name used to describe Ferro-hornblende and Magnesio-hornblende, but the term is generally more inclusive for all calcium aluminum amphiboles. We now call it Fossil Fuels. A key reason is that many minerals are only stable under specific conditions. Most of the familiar non-metallic minerals in the earths crust have a specific gravity of 2.5 to 3. Lamprophyres are a group of rocks containing phenocrysts, usually of biotite and amphibole (with bright cleavage surfaces), and pyroxene, but not of feldspar.They are thus distinguished from the porphyries and porphyrites in which the feldspar has crystallized in two generations. This can be determined by using a Jolly balance, beam balance, pycnometer etc. They are essentially dike rocks, occurring as dikes and thin sills, and are also found as marginal facies Specific Gravity of Augite =3.40 gm/cc. The natural rocks were collected from Wadi El-Anbgy, El-Quseir-Egypt. Two models are built one for collapse potential obtained by single oedemeter test and the other is for collapse potential obtained by double oedemeter test.
