It has about 50% silica content but is a mafic rock which means it has higher magnesium and iron content. 90% of all volcanic rocks are basalt. It is used in construction and road infrastructure.

Isotope analysis of the basalt shows that it contains 12.5% 40K and 87.5% 40Ar. If the half-life of the decay of 40K to 40Ar is 1.3 billion years, then how old is the basalt?

Stone mediums for these Egyptian carvings included granite, quartz, diorite, limestone, and basalt. In addition to these, Egyptian craftsmen used wood, clay, and bronze for their carvings.
