【Abstract】 Erlian basin underwent a complex development history in Mesozoic and is a multi-folded basin system. It was once a little-scale rift-subsidence basin in early-mid Jurassic, a structural reversal basin in late Jurassic (accompanying strong volcanism), a lager-scale rift subsidence basin in early cretaceous and a structural reversal basin in late of early cretaceous. The region has been in a wholly lifting state since late cretaceous.更多还原
