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.

The average REE content of the Muncung Granite is 265 ppm with Eu anomaly in REE's spider diagrams. Lateritization process has increased REE content by more than four times compared to that in the Muncung Granite. Ce and Eu anomalies in weathered layers can be associated with weathering process and initial REE contents in the host rock.

Until the 1990's, it was envisaged that the magmatic rocks of the Bushveld Large Igneous Province evolved over a long period of time, possibly exceeding 100 Ma. However, research in the last decade has shown that the Rooiberg Group volcanics, the Rashoop Granophyre Suite, the intrusive Layered Suite and Granite Suite were synchronous (Table 2).

The platinum-group metals (abbreviated as the PGMs; alternatively, the platinoids, platinides, platidises, platinum group, platinum metals, platinum family or platinum-group elements (PGEs)) are six noble, precious metallic elements clustered together in the periodic table.
Zircon is common in the crust of Earth. It occurs as a common accessory mineral in igneous rocks (as primary crystallization products), in metamorphic rocks and as detrital grains in sedimentary rocks. Large zircon crystals are rare. Their average size in granite rocks is about 0.1–0.3 mm, but they can also grow to sizes of several centimeters, especially in mafic pegmatites and carbonatites.

Geology. The Stillwater complex is a large layered intrusion with many similarities to the Bushveld igneous complex of South Africa.The complex was intruded into existing gneisses during the Archean at about 2700 Ma. Host rocks on the northern side are Archean sedimentary rocks while the southern boundary includes Precambrian rocks of granite, granite gneiss and schist.

A "pictograph" is a drawing or painting that is created on a rock. It is not "carved" into the rock - that would be a "petroglyph." Shown in the photo above is part of the ancient artwork of "Cave of the Hands," a series of caves in Argentine where ancient people painted on the walls starting over 9000 years ago.

B) After that, (~1.7 billion years ago) the rocks were buried, folded, and uplifted into mountains. The heat and pressure from mountain building created new metamorphic rocks (mostly schist and gneiss). Then, magma squeezed into the rocks to form new igneous rocks (granite).

Mar 13, 2018· When you crush a rock, its powder isn't always the same color as the rock itself, and this powder can help identify the minerals in the rock. You obviously don't want to crush your rock if you think it's valuable, but that isn't necessary. You can conduct a streak test with a piece of unglazed porcelain – the back of a porcelain tile is ideal.
