| 英文摘要 | Based on the plate reconstruction which shows that most core parts of present cratons locate in the interior of the continents during the supercontinent cycles, we propose that the oceanic subduction initiation may trigger the destruction of marginal cratonic lithosphere. We develop a simplified force analysis for the destruction of subcontinental lithospheric mantle (SCLM) by the subduction initiation. Our analysis suggests three key parameters: the SCLM thickness, the contact angle between SCLM and oceanic plate, and the coefficient of friction of the SCLM. Our numerical models further support our analysis and demonstrate that a thicker SCLM with a larger contact angle is easier to be destructed by subduction initiation, and the yield strength of the SCLM has a significant impact on the spatial range of its destruction. Our results provide important insights into the parameters controlling cratonic lithospheric destruction and explain the distribution of preserved cratons in the interior of continental plates. Plain Language Summary According to the present location of craton cores, we put forward that the subduction initiation of the oceanic plate can destroy the marginal parts of cratonic lithosphere directly contacting with subduction zones that explain the distribution of cratons during the supercontinent cycle. We used numerical models for the destruction of subcontinental lithospheric mantle (SCLM) by the subduction initiation which suggests three key parameters: the SCLM thickness, the contact angle between SCLM and oceanic plate, and the coefficient of friction of the SCLM. From our results, these parameters, which control the destruction, can explain the distribution of preserved cratons in the interior of continental plates. |
