| 摘 要： | 坨32井区火山岩岩石类型主要有流纹岩、粗安岩、安山岩,流纹质火山角砾岩,流纹质凝灰岩,安山质火山角砾岩,安山质凝灰岩。火山岩的喷发时代为(97.37±1.41)Ma和(79.52±1.25)Ma,喷发为两期5次,第1期为早白垩世晚期,第2期为晚白垩世中期。火山的喷发具有“反序”现象,利用岩浆流体动力学理论论证了这种“反序”现象是因为存在带状岩浆房,并建立了带状岩浆房和地表火山岩分布的模型。

| Abstract: | 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. |
