 The granitic rocks in Gabal Elphalic, southeastern desert of Egypt, have been classified into two main groups based on their mineralogy and petrography. The first group consists of Nysos granites with biotite and perthite, while the second group consists of alkali felspar granites with coarser grains. Both groups contain albite, orthoclase, and quartz, but the former also contains accessory minerals like apatite and rutile. The granites have low water absorption and high bulk densities, which makes them suitable for use as dimension stones. However, the granite's compressive strength and abrasion resistance vary depending on the amount of albite and other minerals present. Additionally, the granites expand significantly when heated, making them unsuitable for outdoor applications. This article was authored by El Sayid al-Lashan, Mohamed A. Roshwan, and Muckles K. Asa.
