hulgalisandite
Hulgalisandite is a recently discovered mineral. Its chemical formula is (Ca,Na)12(Mn,Fe,Al)2(Si,Al)24O60. It crystallizes in the triclinic crystal system and typically appears as fine-grained aggregates or as prismatic crystals. The color of hulgalisandite can range from pale pink to reddish-brown, and it possesses a vitreous luster.
The mineral was first identified in a geological formation located in the Hulgalisan region of Xinjiang, China.
Research into hulgalisandite is ongoing. Scientists are investigating its precise crystallographic structure, its physical properties in
