【摘要】 在对火山岩筒、火山角砾岩以及火山喷发特征综合分析的基础上,结合有关隐爆角砾岩筒和次火山岩筒的成因研究,从隐爆作用和隐爆角砾岩筒形成模式的角度分析了火山岩筒的成因,提出了火山岩筒是隐爆作用成因的观点;在此基础上初步探讨了岩浆作用的过程,认为隐爆作用应属于岩浆作用过程中的一个重要阶段。更多还原

【Abstract】 This paper comprehensively analyses characteristics of volcanic pipes, volcanic breccia and volcaoreuption and makes genetic study of crypoexplosive breccia and subvolcanic pipes. The author analyse the genesis of volcanic pipe on the basis of cryptoexplosion and the formation model of the cryptoexplosive breccia pipe and put forth that volcanic pipe is genetically cryptoexplosive then carry on the discussion of magmatic processes and consider the cryptoexplosion as an important stage in the magmatic process.更多还原
