Clinozoisite
Clinozoisite is a silicate mineral recognized among collectors for its crystal form and distribution, with known Chinese sources.
About Clinozoisite
Clinozoisite belongs to the silicate class in the epidote group and has the chemical formula Ca2Al3(Si2O7)(SiO4)O(OH). It crystallizes in the monoclinic system and holds a steady position among silicate species.
Identification & care
Crystals commonly develop as prismatic, striated along length, tabular, massive. Its color range is broad, including colorless, pale yellow, pale green, and pale pink (thulite = mn-bearing — see id 432). The luster is vitreous, the streak is white, and specimens range from transparent to translucent. The cleavage is perfect {001}. The fracture is uneven to conchoidal, which aids identification.
Collector context
Collector notes
Clinozoisite holds a steady place in systematic mineral collections. Clinozoisite is widely represented across Chinese provinces, including Heilongjiang, Gansu, Anhui, Guizhou.
