32rakuline

32rakuline is a mineral that was first discovered in 2019 in a mining locality in Madagascar. It is a rare titanium phosphate mineral that belongs to the apatite group of minerals. Its chemical composition is (Ti, Mn)₃(PO₄)₂(OH,F).

32rakuline is characterized by its unique crystal structure, which consists of titanium and manganese ions octahedrally coordinated to phosphate groups. The mineral has a reddish-brown to dark brown color and a vitreous luster. It is typically found in association with other minerals such as quartz, feldspar, and apatite.

The discovery of 32rakuline in Madagascar is significant due to the country's rich mineralogical history. Madagascar is known for producing a wide variety of minerals, many of which are found in unique and isolated locations. The discovery of 32rakuline has added to the country's mineralogical diversity and has provided insights into the geological processes that have shaped the region.

32rakuline has been obtained synthetically through the hydrothermal growth of titanium and manganese phosphates. The synthetic production of 32rakuline has enabled scientists to study the mineral's properties and behavior in controlled laboratory conditions. However, natural occurrences of 32rakuline remain relatively rare, and further research is needed to fully understand the mineral's geochemistry and geological significance.
