... elemental analyses were employed. Our results reveal that the Carboniferous strata are likely marine deposits consisting mainly of clastic rocks interfingering with volcanic rocks and minor cherts and limestones. The 330–310 Ma sandstones were dominantly sourced from the local Yagan and Zhusileng-Hangwula...
