The formation of platinum-palladium nuggets is little understood (supergene versus hydrothermal versus magmatic). Córrego Bom Sucesso, situated in the mining district of Serro in Minas Gerais, Brazil, is well known for its historic Pt-Pd nuggets, as well as for alluvial gold and diamond occurrences. There is very little geological information available on this famous area which holds promise to better understand the formation of Pt-Pd nuggets. The source of the platinum-group metals is also unknown, similar to the in situ jacutinga-style gold-palladium mineralisation in Brazil, and will be constrained by osmium isotope data.

铂-钯金块的形成人们知之甚少（表生矿、热液与岩浆），位于巴西米纳斯吉拉斯州塞罗矿区，以其历史悠久的铂-钯金块而闻名。这个著名地区的地质信息很少，但有希望更好地了解铂钯矿块的形成。铂族金属也是未知的，类似于巴西的原位 Jacutinga 式金钯矿化，并将受到锇同位素数据的限制。
