摘要: 基于现今实测全球板块运动模型ITRF2000VEL,分别建立了相对东太平洋海岭和南北大西洋海岭的绝对板块运动模型PRF-ITRF2000VEL、SRF-ITRF2000VEL和NRF-ITRF2000VEL,由此分析了大洋海岭间的相对运动,表明大西洋海岭与东太平洋海岭以平均10.9mm/a的速度在张开,反映了大洋海岭并非固定,由此得到的绝对板块运动模型均是"相对"的绝对板块运动模型。

Abstract: This paper develops new absolute models of plate motion relative to ocean ridges:PRF-2000VEL model with respect to the fixed Pacific Ridge,SRF-2000VEL model with respect to Southern mid-Atlantic ridge and NRF-I2000VEL model with respect to Northern mid-Atlantic ridge,analyze and compare the absolute motions of lithospheres relative to Pacific Ridge,Southern mid-Atlantic and Northern mid-Atlantic Ridge,respectively,which shows the Eastern Pacific mid-ridge and the mid-Atlantic Ridge is extending at the even 10.9mm/a rate.
