尽管气候演变的历史不同,但是世界上许多最富的砂金矿都出现在寒冷地区。因此,在风化过程中,寒冷气候条件与金的部分化学性状之间可能存在着某种内在的联系。北极地区许多砾石和土壤的砂矿中,金以自形晶出现,对此尚未作出合理的解释。上述设想和现象使我想起低温下金的地球化学性质。 Despite the different histories of climate change, many of the world’s richest placer gold deposits are found in cold regions. Therefore, during the weathering process, there may be some intrinsic relationship between the cold climatic conditions and the partial chemical properties of gold. Many of the gravels and soils in the Arctic sand, gold to prongs appear, this has not yet made a reasonable explanation. The above assumptions and phenomena remind me of the geochemistry of gold at low temperatures.
