WebJan 21, 2024 · The origin and formation of granitic rocks was at the forefront of geological debate before and after the pioneering work of James Hutton and Charles Lyell, and played an important role in the development of continental drift theory ( Wegener, 1924; Du Toit, 1937; Holmes, 1945; Bowen, 1948 ). WebAplite is an intrusive igneous rock in which the mineral composition is the same as granite, but in which the grains are much finer, under 1 mm across. Quartz and feldspar are the dominant minerals. The term aplite or aplitic is often used as a textural term to describe veins of quartz and feldspar with a fine to medium-grain "sugary" texture.

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. WebMontgomery County, Kansas. Date Established: February 26, 1867. Date Organized: Location: County Seat: Independence. Origin of Name: In honor of Gen.
