Orebodies in sedirmentary rock hosted Au deposits are discrete hypogene and epigenetic masses usually hosted in a fault zone, breccia mass, or lithologic bed or unit.
So the distribution and the content of conglomerate were different, and its geological phenomenon in the data of drilling, outcrop, logging and seismal section in different area.
Then we transitioned from that crater floor into the sedimentary deposits and now we're here in sandstones, conglomerates, mud stones, the kinds of rocks that are deposited by flowing water.
Using this method Dr Granger and colleagues determined, in 2015, that the breccia in Member 2 is 3.7m years old—1.5m years more ancient than originally thought.
When a breccia-forming object falls into a cave, it finds itself shielded from cosmic rays, and the steady decay of its existing cosmogenic nuclides can be used to determine how long ago it fell in.
