An Approach to the Origin of Volcanoes
详细信息   
摘要

The origin of volcano results from that the state of the mantle solid substance is changed, resulting in substances’ differentiation. There are basic conditions for the formation of volcanoes, namely, displacement substances, displacement space and eruption channels. There are five existing states of volcanoes: perennial, intermittent, opening, ending and under-erupted ones, which are highly related with the velocity of substance displacement. And the distribution of the volcanoes in geohistory early periods is strongly affected by the degree of impinging planetesimals, and that in later periods is mainly affected by subducted plates.
