old man emu Posted January 25 Posted January 25 The African Plate is moving towards the Eurasian Plate at a rate of 2.15 cm per year, causing subduction where oceanic crust is converging with continental crust. The Arabian Plate is moving in a similar direction, but the Somali Plate is moving away from both. That is causing the split which can be seen as the Great Rift Valley of East Africa which lies along the boundary of the African and Somali Plates. 1
facthunter Posted January 25 Posted January 25 Don't rush to watch and hold your breath It will take 10's of millions of years. The "Wegener THEORY of Continental drift " was taught in the 50's Look it up. The Earths crust is only about 40 miles deep Movement causes Mountains to form and volcanoes when plates over lap . See it's NOT flat or bits would slide of the edge. Nev 1
Grumpy Old Nasho Posted January 26 Posted January 26 With the movement of the plates, unearthed cold nuggets would be glittering in the sunlight, just a matter of poking them out and off to the dealer. 1
onetrack Posted January 26 Posted January 26 Gold actually travels in solution via chemically active water through the soils, and reaches points where it precipitates out as the metal. Thus the reason for the totally random formation of nuggets. The Golden Eagle nugget was found at Larkinville W.A., just 45kms from my gold mine at Higginsville. I've been into the spot where the Golden Eagle was found, and it's a totally unimpressive patch of flat red clayey ground, with no normal signs of gold-bearing country, such as quartz or calcrete, as is common in the W.A. Goldfields. Yet, a dig by 16 yr old Jimmy Larkin found the biggest nugget ever found in W.A., just half a metre below the surface. When I was at Higginsville, a mining company started up an open pit just a few kms South of the old Higginsville townsite. One night, the conveyor transporting ore to the crusher stopped dead. The workers went to find the problem, and found a 42 oz nugget had jammed the conveyor, and brought it to a halt!! https://www.goldindustrygroup.com.au/news/2017/9/18/finding-of-golden-eagle-nugget 1 1
old man emu Posted January 26 Posted January 26 Having seen the NSW and Victorian goldfields, I'm astounded when I see the WA goldfields countryside. The two types of countryside are so different. 1 1
onetrack Posted January 26 Posted January 26 ERROR CORRECTION: My memory is getting faulty. The Golden Eagle nugget finder in January 1931 was Jimmy Larcombe, not Larkin. As a postscript to the Larcombes life story, Jim Larcombe Snr purchased the Terminus Hotel in Lane St Boulder in July 1933, and after re-naming it the Golden Eagle Hotel, he and his wife moved in as owners and operators. However, Mrs Larcombes life was cut short in 1942 when she had a stroke whilst working in the Hotel. She was taken to Hospital, where she died shortly after. Jim continued to operate the Golden Eagle Hotel, but sold it sometime in the 1960's I think, and purchased the Foundry Hotel in Kalgoorlie. Unfortunately, the Golden Eagle Hotel started to fall into disrepair in the 1980's and then became abandoned as an operating hotel in the early 2000's. Then the 5.2 magnitude Kalgoorlie-Boulder earthquake of 2010 caused serious structural damage to the building, and it was then deemed by the owners to not be economically repairable, and was slated to be demolished. However, before that could be carried out, someone set fire to the hotel, leaving it a smoking ruin. What was left was then demolished, thereby reducing the number of historical original hotels in Boulder by one more. 1
pmccarthy Posted January 26 Posted January 26 I have visited the sites of several large nugget finds in Victoria and they are quite ordinary, usually with no other large gold nearby, though there may have been back in the day. 2
old man emu Posted January 26 Posted January 26 I have learned how the gold deposits of NSW and Victoria formed as a result of mountain building (orogeny). The stumps of those mountains still exist. But the WA goldfields don't appear to have mountains. I have also learned that Uluru is the eroded remnant of an very ancient mountain range. I wonder if the gold deposits of WA are simply sediments eroded from ancient mountain ranges. But I have no knowledge of the geology of those goldfields. I base it on some shows I seen on the Discovery Channel which depict the countryside. 1
