Bushveld Igneous Complex Wikipedia

The Bushveld Igneous Complex (BIC) is the largest layered igneous intrusion within the Earth's crust. It has been tilted and eroded forming the outcrops around what appears to be the edge of a great geological basin: the Transvaal Basin.It is approximately 2 billion years old and is divided into four different limbs: the northern, southern, eastern, and western limbs.
