About Outback Jasper :-Outback Jasper was discovered many years ago by fossickers but was not dug commercially until last year. It occurs as a narrow seam within an outcrop of banded chert. The location is in the midwest region of Western Australia near the small gold mining centre of Payne's Find. Jasper is an opaque rock of virtually any color stemming from the mineral content of the original sediments or ash. Patterns arise during the consolidation process forming flow and depositional patterns in the original silica rich sediment or volcanic ash. Hydrothermal circulation is generally thought to be required in the formation of jasper.
