WebPegmatites in the Adirondack Lowlands are related to the calc-alkaline arc magmatism of the Antwerp–Rossie granite suite and yield U–Pb zircon crystallization ages that indicate intrusion during the late Shawinigan orogeny (~1195 Ma); currently there are no known pegmatites related to the Ottawan and Rigolet orogenies in the Lowlands. WebThe Bushveld (or Lebowa) granites are typically A-type granites with two lithologies: the medium-grained Nebo granite is the main petrographic type, with a minor fine-grained variant, the Klipkloof granite. The granite roof penetrates the Rooiberg rhyolites of nearly identical age (2061 Ma) and chemical composition.

Genetic affinity and tectonic setting WebGranite is an igneous rock composed primarily of quartz, feldspar, and mica minerals which gives it a speckled appearance. Granite is also a very hard and dense rock, making it an ideal choice for countertops. Granite is typically formed in a continental plate tectonic setting, where magma slowly cools below the Earth's surface.
