from Wikipedia, the free encyclopedia

The Pine Creek Orogen (English: Pine Creek Orogen ) describes a mountain formation ( orogen means mountain formation ) in the Northern Territory in Australia , which took place from 2050 to 1800 years in the Paleoproterozoic in Australia. It is named after the Pine Creek River .

It is part of the Kraton located in northern Australia . The 66,000 km² area is a region with the most important metal deposits in Australia. The mountains lie on a base from the Archean era from 2670 to 2500 million years ago.

The mountain range consists mainly of granites and gneisses that have been partially covered by sediments . In the sediment deposits there are greywacke , sandstone , claystone , dolomite . Other types of rock that occur include tuff , granite, volcanite , dolerite , basalt , mica schist and quartzite . The rock layers reach a thickness of 14 km. The layers are partially overlaid by the McArthur Basin , Birrindudu Basin , Daly Basin , Arafura Basin and Money Shoal Basin .

The mountains contain deposits of gold , uranium , metals, platinum group metal , iron , manganese , magnesite and phosphate . The Ranger uranium mine is located in the Pine Creek Orogon . There is still an active search for gold and uranium.
