The role of the Cathaysia Block, South China, and its linkage with orogenesis in the Rodinia and Gondwana supercontinents remain unresolved because of uncertainties in its paleoposition in supercontinental reconstructions. The lithostratigraphic, geochronologic, geochemical (including isotopic), and paleocurrent data on late Neoproterozoic to early Paleozoic sub-basins in the Cathaysia Block reveal spatio-temporal, tectono-sedimentary, and provenance diversity that show linkages with previously adjacent terranes and orogens in East Gondwana. An abundance of siliceous and conglomeratic rocks, local unconformities, and pinch-out in certain layers indicate a late Cryogenian proximal deposition, late Ediacaran transgression, and Middle Cambrian uplift. Cryogenian to early Ordovician strata contain predominantly 1000–900 Ma (late Grenvillian age) detrital zircon population, whereas 1300–1050 Ma (early Grenvillian age) zircons are only dominant in strata earlier than late Ediacaran. Besides, 850–700 Ma zircons are the most prominent group in the Middle Cambrian strata along with an occasional increase in the 650–500 Ma (Pan-African age) zircons.The Grenvillian age zircon groups exhibit significant sediment input from the eastern Indian terrane (990–950 Ma) and western Australia (1300–1050 Ma), underlining the fact that the Cathaysia Block was located between these two terranes in the northern part of East Gondwana. The diminishing contribution of early Grenvillian components in the late Ediacaran strata can be linked to the Pinjarra Orogeny (550–520 Ma), which led to uplift that blocked the transport of detritus from Australia. Middle Cambrian provenance variation with high abundance of 850–700 Ma components indicates the presence of intrinsic sediment from the Wuyishan terrane of South China. Given that the Cathaysia Block was a passive continental margin, this change was caused by the uplift of the southeastern Cathaysia Block, which was related to the far-field stress effects of the late phase of the Kuunga Orogeny (530–480 Ma). The decrease in abundance of early Grenvillian and Pan-African zircons in space implies that they were transported into the basins through independent drainage systems. This is consistent with the local and temporal variations in paleocurrent orientations during the Cambrian, further implying diverse and complex drainage systems in the southwestern Cathaysia Block during this period.

华南华夏地块的新元古代晚期至古生代盆地早期演化：时空时空变化对超大陆周期古地理重建的影响

由于在超大陆重建中古环境的不确定性，华南华夏地块的作用及其与罗丹尼亚和冈瓦纳超大陆的造山作用的联系仍未得到解决。在华夏地块的新元古代晚期到古生代早期盆地的岩石地层学，地球年代学，地球化学（包括同位素）和古流变数据揭示了时空，构造-沉积和物源多样性，表明与东部东部先前相邻的地层和造山带有联系冈瓦纳。大量的硅质岩和砾岩岩，局部不整合面以及某些层中的夹挤表明晚期冰晶期近端沉积，晚期埃迪卡拉级海侵和中寒武统隆升。低温至奥陶纪早期地层主要含有1000-900 Ma（格伦维利晚期）碎屑锆石，而1300-1050 Ma（格伦维利亚早期年龄）碎屑锆石仅在Ediacaran晚期占主导地位。此外，850–700 Ma锆石是中寒武纪地层中最突出的类群，偶尔增加了650–500 Ma（泛非时代）的锆石。格伦维利亚时代的锆石类群显示了来自印度东部地层的大量沉积物输入。 （990-950 Ma）和西澳大利亚州（1300-1050 Ma），强调了一个事实，即华夏地块位于东冈瓦纳北部的这两个地块之间。Ediacaran晚期地层中早Grenvillian成分的贡献可能与Pinjarra造山带（550-520 Ma）有关，这导致隆升，阻碍了碎屑从澳大利亚的运输。寒武纪中部物源的变化（850-700 Ma的高丰度）表明存在华南武夷山地体的固有沉积物。考虑到华夏地块是一个被动的大陆边缘，这种变化是由东南华夏地块的隆起引起的，这与昆格造山带后期（530-480 Ma）的远场应力作用有关。早期格伦维连和泛非锆石在太空中的丰度下降意味着它们是通过独立的排水系统运入盆地的。这与寒武纪期间古流向的局部和时间变化是一致的，
