摘要

尽管相对于冈瓦纳大陆周围的伊比利亚地块的其他主要区域，南葡萄牙带具有所谓的奇异性质，但伊比利亚黄铁矿带最古老地层的泥盆纪碎屑岩与奥萨-莫雷纳带的新元古代寒武纪岩石和西梅古马的寒武纪-奥陶纪岩石有着显著的相似性，提出所谓的“西非签名”。

Detrital zircon similarities and dissimilarities between the Iberian Pyrite Belt, Ossa-Morena Zone and Meguma

Despite the so-called exotic nature of the South Portuguese Zone relatively to the other major domains of the Iberian Massif of peri-Gondwanan affinity, Devonian detrital rocks of the oldest strata in the Iberian Pyrite Belt have a remarkable resemblance with the Ossa-Morena Zone’s Neoproterozoic-Cambrian rocks and the West Meguma’s Cambrian-Ordovician rocks, presenting the so-called “West African signature”.
