These rocks mainly consist of feldspar, quartz, mica, and amphibole minerals, which form an interlocking, somewhat equigranular matrix of feldspar and quartz with scattered darker biotite mica and amphibole (often hornblende) peppering the lighter color minerals. Occasionally some individual crystals (phenocrysts) are larger than the groundmass, in which case the texture is known as porphyritic. A granitic rock with a porphyritic texture is known as a granite porphyry. Granitoid is a
Rock art of Uganda thought. Archaeologists strive to better understand cultures of the past, figuring out the meanings behind these paintings could help archaeologists to better understand what culture made them. Nyero is one of the most important rock art sites not just in Uganda but in Africa as well. It has well-preserved rock paintings that are utilized in study of rock art. The Nyero site was discovered by C.A.E Harwich in 1945. Nyero was the first rock art site to be catalogued and described in full within Uganda. Nyero itself is composed of granite, and just under 40m high. There are two areas
