Precise age determination of mafic and felsic intrusive rocks from the Permian Emeishan large igneous province (SW China)

Radiogenic isotopic dating using different (mainly micro-beam analyses) techniques of rocks from the Emeishan large igneous province (ELIP) has yielded a range of ages from the Capitanian to the Early Triassic. In contrast, estimates based on paleontological and paleomagnetic data suggest the ELIP was emplaced rapidly (≤ 2 Ma) and that volcanism ended by ~ 257 Ma. New zircon CA–TIMS U–Pb ages, that have superior precision compared to ages from...
