Re os dating arsenopyrite
This method has been applied to better understand the origins of global Oceanic Anoxic Events (OAEs), the timing of shale deposition and correlation in Precambrian sedimentary basins and this rise of oxygen on Earth.
from Oligocene Cu–Mo–Au re-os dating veins in the Qarachilar area, Qaradagh batholith (northwest Iran): implications for.The data suggest that the Carlin-like gold deposits formed in Late Triassic to Early Jurassic, which is clearly earlier than the ca.100–80 Ma acid to ultra-basic magmatism in this part of southwestern China. The ages are consistent with ore formation during a period of post-collisional lateral transpression, which is similar to that of the Carlin-like gold deposits in western Qinling of China, but quite different from Carlin-type gold deposits in Nevada, U. The Maoling gold deposit, one of the large gold deposits in eastern Liaoning Province, NE China, is an arsenopyrite-disseminated gold deposit with a resource of approximately 25 t Au and an average Au grade of 3.2 g/t.
