WebHow is orthoclase feldspar formed? Most orthoclase forms during the crystallization of a magma into intrusive igneous rocks such as granite, granodiorite, diorite, and syenite. Significant amounts of orthoclase are also found in extrusive igneous rocks such as rhyolite, dacite, and andesite. Web9 apr. 2024 · Clays are formed when dissolved feldspar reacts with H+ or OH ions. The reaction also produces new ions in solution, with the form of feldspar reacting controlling the variety of ions produced. Clays are plentiful weathering materials due to the presence of feldspars in the Earth's crust.
Weborthoclase may occur with albite in rocks. In some igneous rocks and in most metamorphic rocks, microcline is the common potassium feldspar. Microcline can accommodate only a little sodium and, like orthoclase, may occur with albite. All the potassium feldspars can contain more sodium at high temperatures than at low.
