| 英文摘要 | Through chronological research of the 106Ma asthenosphere-originated depleted mantle basalts and study on the plane of unconformity on bottom of the basalts, it is recognized that: (1) there have been "magmatic hiatus" and strong tectogenesis occurring with replacement of the lithospheric mantle materials, revealing correlation between 4 elements-upwelling of diapers of asthenosphere, lithosphere thinning, magmatic hiatus, and strong tectogenesis, among which upwelling of materials and heat energy with asthenosphere melts is the initiative factor and the lithosphere thinning is critical; (2) comparison of the 116Ma, 106Ma, 93Ma, 80Ma, and 45Ma volcanic rocks reveals an irreversible and very long process of lithospheric-mantle replace starting from 106Ma; and (3) comparing evolution of the volcanic rocks in this area and the contemporaneous thermal spreading of its adjacent oceanic plate suggests that it is perhaps the same deep thermal disturbance beneath the lithospheric plate that controls the synchronic evolutional features of the oceanic and the continental plates in the Late Mesozoic ( 120 similar to 80Ma). |
