Jun 15, 2021· The volcanic assemblage includes metabasalt, a group of andesites with subordinate basalts (the Hamash Volcanics), and felsic volcanic porphyry. The plutonic rocks include a dioritetonalite series, finegrained granite, and granite porphyry. The volcanic rocks are generally subalkaline and feature a strong depletion in Nb and Ta.

(1984) classified g deposits in Egypt into three formations namely gsulphide formation, skarn gferruginous quartzite formation and g quartz formation. Although this classification is the first actual attempt at classifying g deposits in Egypt, it ignores the tectonic setting of host rocks, as well as the source of the mineralizing fluids.

Diorite is an intrusive igneous rock of intermediate composition. Uses of Diorite. In areas where diorite occurs near the surface, it is sometimes mined for use as a crushed stone.It has a durability that compares favorably to granite and trap rock.It is used as a base material in the construction of roads, buildings, and parking areas.

Uses of G in the Ancient World. G was among the first metals to be mined because it commonly occurs in its native form, that is, not combined with other elements, because it is beautiful and imperishable, and because exquisite objects can be made from it.
