RedDirtDigger Posted October 9, 2021 Share Posted October 9, 2021 In much of the gold rich areas in Western Australia the rock has been above the ocean exposed to erosion for 2.4 billion years (give or take a week or two). Over a kilometre of ground has been denuded down in that time. Eroded material has washed away to the ocean. (Leaving some gold behind, scattered far and wide as the landsurface lowered, so luckless prospectors find a lone nugget with no friends around it) Whats scary is you can detect smooth alluvial nuggets formed 2.4 billion years ago and deposited in river conglomerates laid down in basins 2.4 billion years ago. And the once level conglomerate (river) rock layer is now tilted vertical and maybe extends kilometres deep. 1 1 Link to comment Share on other sites More sharing options...
