![]() ![]() The vesicular group (the permeable one) is characterized by fair to very good porosity (∅), good permeability (k), very low true formation resistivity factor (F) and contain micro to ultra micropores. Petrophysically, the studied samples can be grouped into two main groups the first group includes amygdaloidal basalts and the second group consists of vesicular basalts. The degree of oxidation and alteration of magnetite and ilmenite are discussed in detail. The petrographical studies indicated that the studied vesicular basalts are rich in calcic-plagioclase, augite and olivine in addition to numerous amounts of fine opaque minerals and vesicles filled with carbonate and quartz amygdales. ![]() This paper gives an account of the petrophysical characteristics and the petrographical descriptions of Tertiary vesicular and amygdaloidal olivine basalt flows from Wadi Wizr in the central Eastern Desert of Egypt. ![]()
