Urchin Quartz

Urchin quartz (quartz with Mannardite crystals) should probably be included here because it is quartz. I don't know anything about quartz though. Mr moothedisastercat neo (talk) 15:30, 13 December 2022 (UTC)[reply]

Most-common mineral

The first paragraph states that "Quartz is the second most abundant mineral in Earth's continental crust, behind feldspar." However, feldspar is not a mineral. It is a group of minerals, so comparing it to a single mineral like quartz is misleading. A more apt comparison would be silicate minerals to feldspars, or quartz to a specific feldspar like albite. As it is, this is a bit like saying "Ants are the second most abundant species on earth, behind vertibrates."
