bassotoiston
Bassotoiston is a rare and distinctive mineral species, first discovered in the late 19th century. It is named after its discoverer, the Italian mineralogist Giovanni Bassi, and its chemical composition, which includes titanium, oxygen, and silicon. The mineral is typically found in metamorphic rocks, particularly those that have undergone contact or regional metamorphism. Bassotoiston crystals are usually small, ranging from a few millimeters to a centimeter in size, and are often found in association with other titanium-bearing minerals such as rutile and ilmenite.
The mineral's crystal structure is orthorhombic, and it exhibits a distinctive brownish-black color with a metallic
