haïlaborite

Haïlaborite is a rare mineral that was first discovered in Madagascar. Its chemical formula is Ca2Al2(SiO4)2(OH)2, and it belongs to the melilite group of minerals. The color of haïlaborite can range from pale yellow to brownish-orange, and it typically forms in prismatic crystals. It is known for its vitreous luster and is relatively hard, rating around 6.5 on the Mohs scale.

The geological conditions under which haïlaborite forms are quite specific, often found in metamorphosed carbonate rocks that have undergone low-grade alteration. Its rarity means that it is not a commercially significant mineral, but it is of interest to mineralogists and collectors due to its unique composition and occurrence. The name "haïlaborite" is derived from the location of its discovery, the Haïlabor site in Madagascar.

Research into haïlaborite has contributed to the understanding of mineral formation processes in specific metamorphic environments. While not widely known, its discovery adds to the diverse array of minerals found on Earth and highlights the ongoing potential for new mineral finds in remote or geologically active regions.
