Some problems in the research of adakite

Based on the analysis for the state in the research of adakite in China, this paper discusses the major advances in the research of adakite, and probes in to the particular geodynamic significances that are less or out of noticed before.This paper emphasizes that O-type adakite may be as an indicator to reveal the start of oceanic shrink and subduction, whereas the C-type adakite maybe indicate that the crust has thickened before the forming of this kind of magma.And then, the authors point out that many problems of adakite may be resolved by studying the adakite in Tibetan Plateau.
