Sažetak
Carlin-type gold deposits exposed within and along bor-ders of the Triassic Songpan-Garze Flysch and adjacent areas ofnorthwestern Sichuan and southern Gansu Provinces, Western China, have been investigated. Field data suggest that formation of theseCarlin-type gold deposits is related to late-orogenic, calcalkalinemagmatism. Results from two preliminary U-Pb single-zircon analy-ses suggest an age of ca. 220 Ma for magmatism at A’gyi and Dashuideposits. Magma emplacement was likely related to regional de-formation. Calcite associated with ores precipitated from low-salin-ity fluids containing Na+, Mg2+, Na+> Mg2+, +K+andCa2+attem-peratures of up to 300 °C, plausibly under boiling conditions.
