Vote for your favorite mineral in #MinCup26! - Quartz vs. Asagiite
It's a classic vs a newbie as the most common named mineral in the crust Quartz is up against an exceedingly-rare sea foam-green mineral discovered just a few years ago Asagiite.

The two-mica syenogranite that intrudes the Lower Permian Angjie Formation and is well exposed. The upper part of the pluton is overlain by volcanic strata of the Paleocene Dianzhong and Eocene Nianbo formations. The two-mica syenogranite is in an intrusive contact relationship with syenogranite and monzonitic granite. The exposed area of the pluton is approximately 42 km2. Two sample sets were collected from the same pluton and show similar petrography. The main mineral assemblage comprises quartz (24%–27%), K-feldspar (50%–53%), plagioclase (13%–15%), muscovite (4%–6%), and biotite (3%–5%), with accessory zircon, monazite, and apatite. K-feldspar locally replaces plagioclase, preserving plagioclase relicts enclosed within K-feldspar. Figure 3a,b show that the mineral composition mainly consists of K-feldspar and plagioclase, with some plagioclase being replaced by K-feldspar; quartz grains mainly exhibit subhedral structure; biotite and muscovite display alteration transitional distribution with K-feldspar.
