Amore 2001 has successfully investigated the gakkel ridge and arctic ocean in vicinity of its geological and geophysical nature, as well as the nature of sea ice and biology in this area. the preliminary onboard petrology and bathymetry results show that the mantle beneath the gakkel ridge with low temperature has only encountered very low degree partial melting during the spreading and there is no any direct relationship between the crust nature and the spreading rate along the gakkel ridge in any simple petrologic way. mantle temperature and fracture zone density also play a major role on the crust nature, besides spreading rate

It is presented that the hydrous fluxing as well as adiaba tic decompression plays an important role in melting of morb - like mantle beneath marina trough. compared with basalts from other back arc basins, it concludes that the magma varies from morb - like to arc - like with the evolution ; during the earlier stage of evolution, there coexist the two morb - like and arc - like lavas, it may be the nature of the magma in back arc basins ( especially in the earlier stage )
綜合馬里亞納海槽和其他弧后盆地玄武巖的研究成果發現，弧后盆地特別是早期擴張的弧后盆地，其巖漿產物均具從似島弧型到似洋中脊型玄武巖的時空演化特徵；同時存在島弧型和morb型兩種熔巖，可能是弧后盆地（特別是早期擴張弧后盆地）巖漿作用的一個共同屬性。
