Mineralization age and genesis of the makeng-style iron deposits in the Paleo-Pacific tectonic domain of South China: In situ LA-ICPMS garnet U-Pb chronological and geochemical constraints

To reveal the genesis of Makeng-style iron polymetallic deposits from SE China in paleo-Pacific tectonic domain, a new analytical method LA-ICPMS garnet U-Pb dating and rare Earth element analysis was conducted for Makeng, Luoyang, Dapai Pantian deposits. The results nine skarn samples these suggested that mainly formed during 137–130 Ma, which is consistent with zircon molybdenite Re-Os ages. This study provides more direct evidence mineralization age relationship between granite, compared previous studies on granites ore fields. Rare (REE) REE patterns four representative show they are similar to typical deposits, but obvious differences distribution types indicate ore-forming process may be distinct due different mineralizing fluid Our result not only also great significance promote application methods research type
