Zhao Hailin, Li Xiaoguang, Chen Zhenyan, et al. Petrology and genesis of Mesozoic volcanic rocks in Tuo32 well block of Liaohe oilfield[J]. 2006, 27(4): 549-556.DOI: 10.11743/ogg20060417.
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.
