本文报道了火山群综合地质考祭的初步结果。通过实地调查和文献资社考证,对“1951年1号火山爆发”提出质疑。大量证据表明当时没有熔岩溢出;盆地中湖泊的形成是在火山喷发之前,不是壅塞成因而是构造成因。

The preliminary results of a comprehensive geological investigation on the volcanic group are reported in this paper. On the basis of field study and the textual research of some documents, the author queries very much the validity of "the eruption of No. 1 volcano in 1951". A host of facts indicate that there was no presence of lava flow in 1951. The lake in this basin was formed before the volcanic eruption. Thus, it is not a checked-np lake, but a tectonic lake in genesis.
