Vote for your favorite mineral in #MinCup26! - Sphalerite vs. Anorthite
Both zinc ore Sphalerite and calcium plagioclase feldspar Anorthite have perfect cleavage that will split cleanly if you hit them with a hammer, but only one can claim a larger split of your votes!

In the Hengyang area, the Fulu Formation consists predominantly of littoral–shallow marine flysch deposits, primarily composed of clastic rocks interbedded with sandstones and carbonates. The iron formation is hosted within the Fulu Formation, with pebbly sandstone observed 30–80 m beneath the iron formation stratum and carbonate rocks appearing 30–50 m above it. The sedimentary sequence follows a rhythmic pattern: pebbly sandstone → clastic rocks → iron formation → carbonate rocks, indicative of a transgressive sequence. The overlying strata consist of Nantuo Formation tillite, which unconformably overlies the iron formation, while the underlying strata are composed of sandstone. The northeastern part of the study area is occupied by the Guandimiao Pluton, emplaced during the Late Triassic (ca. 226–220 Ma), and mainly composed of amphibole–muscovite monzogranite.
