Formation Age and its Geological Significance of Quartz Diorite from Cryptoexplosive Breccia in Dalucao Rare Earth Mine, Sichuan Province

To limit the diagenetic age of quartz diorite in the crypto-explosion breccia of the Dechang Dalucao in Sichuan Province, LA-ICP-MS zircon U-Pb chronology was carried out. The results show that the LA-ICP-MS U-Pb age of the Dalucao quartz diorite zircon is (751.7±4.6) Ma (n=39), indicating that the...
