Abstract New U Pb detrital zircon and U Pb zircon ages of metaigneous rocks in the Aguilas Arc (Betic Chain, SE Spain) allow us to determine the maximum depositional ages of the rocks. Within the Nevado-Filabride Complex, a Late Carboniferous depositional age for the Lomo de Bas schists and quartzites, and a Permian-Triassic maximum depositional age for the Tahal Fm are determined. Within the Alpujarride Complex, the maximum depositional age of the Micaschists and Quartzite Fm is Late Carboniferous and the Meta-detrital Fm was deposited in the Early Permian. Furthermore, the maximum depositional age of the Saladilla Fm in the Malaguide Complex is also Early Permian. The age distribution patterns for the Carboniferous rocks of the Nevado-Filabride and Alpujarride complexes are similar to those from the Cantabrian Zone of the Iberian Massif, suggesting deposition in Carboniferous foreland basins located eastwards of the Iberian Massif. However, age patterns in Malaguide and samples from the North-eastern Iberian Peninsula and South France show strong similarities suggesting that it can be located near those areas in the Late Carboniferous times. The samples with Early Permian maximum depositional ages from the three complexes contain more Paleozoic zircon grains relative to the older Carboniferous samples, but have similar age distribution patterns, suggesting that they were deposited in the same basin. Samples from unconformable Middle Miocene sediments have Early Permian youngest zircon populations and age distribution patterns corresponding to a mixing of detrital zircon grains from the Alpujarride and Malaguide complexes. Furthermore, there is no record of any major felsic rocks formation and/or exhumation event after the Early Permian in those two complexes.

来自西班牙东南部阿吉拉斯弧的碎屑和火成岩锆石颗粒的 U-Pb 年代学：对 Pangea 石炭纪-二叠纪古地理的影响

摘要 阿吉拉斯弧（西班牙东南部贝蒂奇链）变质岩的新 U Pb 碎屑锆石和 U Pb 锆石年龄使我们能够确定岩石的最大沉积年龄。在 Nevado-Filabride 杂岩中，确定了 Lomo de Bas 片岩和石英岩的晚石炭世沉积时代，以及 Tahal Fm 的二叠纪-三叠纪最大沉积时代。在Alpujarride杂岩内，云母片岩和石英岩组的最大沉积时代为晚石炭世，元碎屑组沉积于早二叠世。此外，Malaguide 杂岩中 Saladilla 组的最大沉积时代也是早二叠世。Nevado-Filabride 和 Alpujarride 杂岩的石炭纪岩石的年龄分布模式与伊比利亚地块的坎塔布连带相似，表明沉积在位于伊比利亚地块以东的石炭纪前陆盆地。然而，马拉吉德的年龄模式与伊比利亚半岛东北部和法国南部的样本显示出很强的相似性，表明它可以在石炭纪晚期位于这些地区附近。三个复合体中早二叠世最大沉积年龄的样品相对于旧石炭纪样品含有更多的古生代锆石颗粒，但具有相似的年龄分布模式，表明它们沉积在同一盆地中。来自不整合的中中新世沉积物的样品具有早二叠世最年轻的锆石种群和年龄分布模式，对应于来自 Alpujarride 和 Malaguide 复合体的碎屑锆石颗粒的混合。此外，
