The types of volcanic rocks in Tuo32 well block of Liaohe oilfiled include rhyolite,trachyandesite,andesite,rhyolitic breccia,rhyolitic eruptive tuff,andestic breccia,and andestic eruptive tuff.The volcano erupted five times in two phases in about(97.37±1.41)Ma and(79.52±1.25)Ma,with the first phase in the late Early Cretaceous and the second phase in the middle Late Cretaceous. The 'reverse' phenomenon in volcanic eruptions is explained as the result of a zonal lava chamber based on the theory of lava hydrokinetics.Models of the zonal lava chamber and the surface distribution of the volcanic rocks are built.
