boksiittimalmina
Boksiittimalmina is a rare and complex mineral that is a member of the boksite group. It is named after its chemical composition, which is a combination of boksite and malina, two other minerals that are also part of the boksite group. Boksiittimalmina is typically found in low-temperature hydrothermal veins and in association with other boksite minerals. It is characterized by its dark brown to black color, its metallic luster, and its perfect cleavage in one direction. The mineral has a hardness of 5.5 on the Mohs scale and a specific gravity of approximately 4.5. Boksiittimalmina is not known to have any significant economic value, but it is of interest to mineralogists due to its unique composition and the rarity of its occurrence. Its crystal structure is complex, with a trigonal crystal system and a space group of P3m1. The mineral is often found in small, well-formed crystals or in massive aggregates. Boksiittimalmina is a relatively new mineral, having been discovered and described in the early 2000s. Despite its rarity, it is an important addition to the mineralogical community's understanding of the boksite group and the complex processes that form these minerals.
