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 originally belonging to a metamorphosed greenstone sequence. The depositional setting is interpreted as within a bowl of the ocean floor, and evolved from a divergent margin with volcanogenic contribution, and then later subject to sedimentary processes; mainly flows and chemical sedimentation turbidites.
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.
