Name(s) in local language(s):

Morro da Mina

Gondites and queluzites, the metamorphosed manganese protores, are regularly distributed in the Greenstone Belt, occupying narrow and elongated zones in the metabasaltic and metaultrabasic parts. These protores were cut by granodioritic bodies, pegmatitic and aplitic veins and faults. (from Mineralienatlas)

A sedimentary assemblage of cherts, mudstones, and manganoferrous carbonates originally belonging to a metamorphosed greenstone sequence and hosted in Precambrian schists. The depositional setting is interpreted as within a bowl of the ocean floor, and evolved from a divergent margin with a volcanogenic contribution, and then later subject to sedimentary processes; mainly flows and chemical sedimentation turbidites. These are overlain by the ore--a mantle of Mn oxides created by hydrothermal weathering of carbonates and silica within the sediments extending to the pit depth (200m as of 2019) and as much as 60km along strike.

Ores are rhodochrosite, and spessartine and rhodonite. Gangue minerals are quartz, huntite, annite, phlogopite, clinochlore, and rutile (all unconfirmed).

Conselheiro Lafaiete was formely named Queluz de Minas.
