Overview of the Palaeoproterozoic Bushveld Igneous Province
The Palaeoproterozoic Bushveld Igneous Province in South Africa is comprised of:
-
a suite of mafic sills which intruded the floor rocks of Transvaal Supergroup
-
the bimodal but predominantly Rooiberg Group volcanic province: one of the largest pyroclastic provinces on Earth covering at least 50,000 km2 and up to 3 km thick
-
the Rustenburg Layered Suite, the largest and oldest mafic layered complex on Earth which covers an area of approximately 65,000 km2 and comprises anorthosites, mafic and ultramafic cumulates
-
the Lebowa Granite Suite
-
the Rashoop Granophyre Suite developed at the contacts between the granites and Rustenburg Layered Suite which is comprised of metamorphosed sediments and intrusive acidic rocks.
-
various satellite intrusions of similar age including the Molopo Farms and Nkomati - Uitkomst.
