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.

铂钯金块的形成知之甚少（表生与热液与岩浆）。Córrego Bom Sucesso位于巴西米纳斯吉拉斯的塞罗矿区，以其历史悠久的铂钯金块以及砂金和钻石矿而闻名。在这个著名的地区，几乎没有地质信息，这有希望更好地了解铂钯金块的形成。铂族金属的来源也是未知的，类似于巴西的原地jacutinga式金钯矿化，并将受到锇同位素数据的限制。
