Rodinia超大陆构造演化研究的新进展和主要目标
RECENT STUDY OF THE RODINIA SUPERCONTINENT EVOLUTION AND ITS MAIN GOAL
摘要
Abstract
The researches on Rodinia since 1997 have been reviewed a nd the main goals for further study have been suggested in this paper. Rodinia supercontinent is a supercontinent formed by the aggregation of global blocks during the Neoproterozoic. The aggregation occurred between 1 000 and 1 300 Ma,characterized by the early arc-continent and late continent-continent collisions followed by an extension between 900 and 1 000 Ma.The breakup of the supercontinent occurred after 830 Ma but it was not homogeneous in time and space. It has been inferred that the mantle plume was a main machine to have resulted in this breakup.The “great igneous province” can be used as the key evidence for the development of the plume. It has been preliminarily proved that the breakup process influenced the CO2 cycle in the atmosphere and hydrosphere,which changed the Neoproterozoic global climate and controlled the development of biosphere and sedimentation of CaCO3,Fe,Mn and P in surface layers of the lithosphere.These phenomena can been explained by the Snowball Earth model.关键词
