(Mererani)
Gem mining area 70 km from Arusha, where tanzanite was first found in 1968.
Subdivided in four claims (A, B, C, D) and additional mines.
The occurrence of gem-quality tanzanite and grossular has 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.
