"WebA-type granite is a particular category of the S-I-A-M or 'alphabet' system which classifies granitoids and granitic rock by their photoliths or source. The 'A' stands for Anorogenic or Anhydrous, as these granites are characterized by low water content and a lack of orogenic or transitional tectonic fabric. Other SIAM categories are S, I, and M types. " - Granite tectonic setting

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. WebNote that a granite is the coarse grained equivalent of a rhyolite. That is, if the rate of cooling is very slow a granite will form. The same melt, cooled rapidly, will form a rhyolite.
