Detrital Zircon U-Pb Geochronology of the Dazhuyuan Formation in Northern Guizhou: Implications for Bauxite Mineralization
Published 2013-01-01“…Combined with the regional geological characteristics, it is postulated that (1) the detrital zircons of the aluminous come from the Hanjiadian group (S1hj), which is the important metallogenic parent rocks of the bauxite. (2) The Caledonian orogeny made the collision between the Cathaysian block and the Yangtze block, implying that the Cathaysia block uplifted rapidly and suffered from erosion in the Silurian, which made a foundation providing a large amount of metallogenic material for the formation of the bauxite.…”

The Ordovician Arc–Basin System in the Northern Great Xing’an Range (Northeast China): Constraints from Provenance Analysis of the Luohe Formation
Published 2024-02-01“…The geochemical compositions of the sandstones suggest that the source rocks have continental island arc signatures. Based on the depositional age, sedimentary environment, provenance, and regional geology, it is concluded that the Luohe Formation was deposited in a back-arc basin setting during the formation of the Duobaoshan island arc–basin system in response to subduction of the Paleo-Asian oceanic plate.…”
