Our understanding of Earth's paleogeography relies heavily on paleomagnetic apparent polar wander paths (APWPs), which represent the time-dependent position spin axis relative to a given block lithosphere. However, conventional approaches APWP construction have significant limitations. First, record contains substantial noise that is not integrated into APWPs. Second, parametric assumptions are...

The Great Serpentinite Belt of eastern Australia is a ∼1500 km long dismembered ophiolite assumed to be Cambrian based on studies small (typically <50 m2) exotic meta-igneous inclusions despite contrasting ages (Cambrian—Devonian) and complex P-T histories. To overcome these issues, we studied ∼18 km2 coherent block that provides robust geological context sampling the ophiolite. Zircon U-Pb-Hf-...

Abstract Marine shelves are a ubiquitous feature of modern Earth, developed across wide range scales in many sedimentary basins and representing the flooded portion basin-margin clinoform topsets. Analysis 80 clinoforms from 10 spanning Cenozoic Mesozoic icehouse, transitional, greenhouse climate settings indicates that normalized mean marine shelf width is 33% total measured topset length. The...
