中国大陆及邻区地幔过渡带上覆低速层及其动力学效应
Low-velocity layer atop mantle transition zone and its dynamic effects in Chinese mainland and adjacent regions
摘要
Abstract
The tectonics of Chinese mainland is very complex,with frequent intraplate strong earthquakes and magmatic activities,and the dynamics of these phenomena has attracted considerable attention in the geoscience community.Seismological observations over the past decade have revealed the ubiquitous presence of a low-velo-city layer(LVL)atop the mantle transition zone in Chinese mainland and its adjacent regions,which is generally at-tributed to partial melting induced by volatiles such as water.This paper systematically reviews the distribution,structure,formation,and dynamical characteristics of the detected LVLs in Chinese mainland and its adjacent areas.It focuses on the role of these LVLs in tectonic evolution,including plate subduction,secontary mantle plume ori-gin,seismic activity,and intraplate magmatism,and provides an outlook on future research directions concerning the LVLs.Through this comprehensive review,we aim to deepen the understanding of the partially molten LVLs atop the mantle transition zone in Chinese mainland and its adjacent regions and to promote further development of related research.关键词
