Plagioclase feldspars have a higher calcium content compared to orthoclase feldspars, as well as a different crystal structure. In terms of appearance, plagioclase feldspars often exhibit striations and twinning, which are less common in orthoclase feldspars.

How many elements macke othoclase feldspar?

Orthoclase feldspar is primarily composed of three elements: potassium (K), aluminum (Al), and silicon (Si). Its chemical formula is commonly represented as KAlSi₃O₈, indicating that it contains one potassium atom, one aluminum atom, and three silicon atoms, along with oxygen. In total, this results in a mineral composed of four distinct elements: K, Al, Si, and O.

Which minerals on Mohs' hardness scale can be scratched by quartz?

Othoclase, apatite, fluorite, calcite, gypsum, and talc.
