Gold Nuggets, Spectacular Natural Objects with Wonderful Life Stories

Gold Nuggets are spectacular natural objects. They are formed through a variety of processes around which some debate still exists. It is generally thought that nuggets in rivers are weathered out of their primary host rock and then beaten into more rounded form through sedimentary transportation in riverine systems. Nuggets in saprolites (thick tropical soils formed in place by intensive chemical weathering of bedrock) may be weathered out of their primary host rock in-situ through acidic aqueous weathering that leaches calcium, potassium and sodium out of silicate minerals but leaves behind secondary clay minerals, iron and aluminum oxides, and unreactive gold. Nuggets in ancient deflated desert environments, by their weight, resist the winds that carry away sands and so form part of residual desert pavements – the proverbial yellow brick road. Water, acid, wind. Miraculously, gold is unchanged much by these powerful forces. And nuggets are the evidence.
