We use a method based on a statistical geomagnetic field model to recognize and correct for inclination error in sedimentary rocks from early Mesozoic rift basins in North America, Greenland, and Europe. The congruence of the corrected sedimentary results and independent data from igneous rocks on a regional scale indicates that a geocentric axial dipole field operated in the Late Triassic. The corrected paleolatitudes indicate a faster poleward drift of approximately 0.6 degrees per million years for this part of Pangea and suggest that the equatorial humid belt in the Late Triassic was about as wide as it is today.
我们使用一种基于统计地磁场模型的方法,来识别和校正北美、格陵兰和欧洲早中生代裂谷盆地沉积岩中的倾角误差。校正后的沉积结果与区域尺度上火成岩独立数据的一致性表明,在晚三叠世存在一个地心轴向偶极场。校正后的古纬度表明,泛大陆的这一部分以大约每百万年0.6度的速度更快地向极地方向漂移,并表明晚三叠世的赤道湿润带与现在的宽度大致相同。
