STRUCTURE OF TRAILING CONDUITS OF STARTING PLUMES IN THE EARTH'S MANTLE

LI YIN-TING(Institute of Geophysics, Seismological Bureau of China, Beijing 100081, China)  
The model of starting plumes in the earth's mantle has been widely usedto discuss some important questions in geoscience, such as the reasons of formation oflarge igneous provinces, cause for disintegration of old Gondwanaland, driving factorsfor dynamical processes which occur in intraplates and have moderate or small spacescale, and so on. But in the model derived from laboratory experiments characteristicsand effects of a trailing conduit of starting plumes in the earth's mantle has beenneglected. In a study of the uprising of a mantle plume it is necessary to find outdistribution of temperature and upwelling velocity within the trailing conduit of plumes.In the present paper an approximate analytic solution for distributions of temperatureand velocity within a steady axisymmetric plume has been obtained from the basicequations which govern the structure of the trailing conduit of mantle plumes, andthen we obtain the basic characteristics for the structure of the trailing conduits: thedominant factor for determining the distribution of temperature within the trailingconduits is the heat flux of mantle plumes, whereas the magnitude of upwellingvelocity in the trailing conduits depends not only on heat flux, and mainly on thepattern of depth dependent of viscosity in the mantle. The results demonstrate thatheat losses from the trailing conduits may not be neglected for weak plumes in theearth's mantle and radial mass transfer could not be neglected for strong plumes.
