Characters of 2D TL

3D TL and OSL of quartz occurring in Ashele copper deposit

Xinjiang were ana- lyzed.The contrast experiments of TL and OSL of quartz occurring in tuff

Markakuli fault zone

gold deposits and granite pegmatite close to Ashele copper deposit were also conducted.Notable difference was found in TL and OSL of the quartz samples.The 3D TL of quartz samples from Ashele copper deposit have just two TL peaks at 340nm and 405nm at 170℃.However

there was a TL peak at 560—590nm

which is related to hydrothermal genesis

in quartz samples from the gold deposit and fault zone

and there were TL peaks at 476nm and 625nm

which are related to hypogene magmatism

in quartz samples from the granite pegmatite.The luminescence characters of quartz com- bining with the REE analyses suggested that the ore genesis of Ashele copper deposit is different from hydrothermal genetic gold deposit and Ashele copper deposit is an volcanogenic deposit.
