Late Triassic detrital zircons in meta-turbidites of the Chonos Metamorphic Complex, southern Chile

Herve, Francisco; Fanning, Christopher

Description

Sensitive High Resolution Ion MicroProbe (SHRIMP) U-Pb age determinations of detrital zircons from metasandstones of the Chonos Metamorphic Complex reveal a significant population of Late Triassic ages. One of the samples is immediately underlying the coquinaceous bed containing fossils which were initially identified as Late Silurian-Early Devonian, and more recently as Late Triassic faunas. The zircon data confirm the latter age as the depositional age of the fossil bearing rocks, excluding...[Show more]
