金是人类发现和应用较早的金属,且是从发现利用自然块金开始的。人类对块金成因的探索、研究很早就开始了,曾设想是太阳影响下发育形成的。这一成矿理论曾避免了西班牙与英国为争夺美洲西北海岸边境一些地带主权的战争。迄今对其形成机制有碎屑说、化学增生说、微生物成矿说等,仍众说纷纭,是个未完全解开之谜。 1、何谓块金目前国内外对块金的分类分级,无统一标准,但习惯上将单块质量在0.5g以上的金块称为块金0.5g～50g称为小型块金,50g～500g称为中型块金,500g～5000g称为巨型块金,>5000g称为巨大型块金。块金的质量越大,组分越奇特,形态越优美。结晶
Gold is a metal discovered and applied earlier by humans, starting with the discovery of the use of natural gold. Human exploration of the cause of gold, the study began very early, had envisaged the development of the formation under the influence of the sun. This mineralization theory has averted the war between Spain and Britain over the sovereignty over some areas along the northwestern coast of the Americas. To date, there are still many opinions about the mechanism of formation, such as chemical proliferation, microbial mineralization, and so on. It is a mystery that has not been fully solved. 1, what is the gold block At present, the classification of domestic and foreign gold bullion classification, there is no uniform standard, but the habit of a single block of quality in more than 0.5g of gold bullion as gold 0.5g ~ 50g called small gold, 50g ~ 500g Known as medium-sized gold, 500g ~ 5000g called giant gold,> 5000g called huge gold. The greater the quality of gold, the more exotic components, the more beautiful form. crystallization
