Merelani tanzanite mines (Mererani)
The Merelani tanzanite mines or Merelani Gem mining area is an area 2 km wide and 50 km long. It is located in the Merelani Hills, on the slopes of the Lelatema Mountains, about 70 km southeast of the town of Arusha, where tanzanite was first found in 1968.
Subdivided into four mining blocks (A, B, C, D) and additional mines.
Gem-quality tanzanite and grossular have been found to occur mainly in boudinaged pegmatitic veins and hydrothermal fracture fillings. These fracture fillings occur in brecciated and hydrothermally altered graphite-bearing gneiss in a mineral association containing glass-clear quartz, diopside, zoisite, graphite and calcite.
Gem-quality yellow-green to green diopside and tremolite contain traces of V and possibly Cr (Fritz et al., 2007).
