The Skoura inlier in the Moroccan High Atlas consists of thick Precambrian–Paleozoic formations. It displays, in the western part near Aguerzega village, a volcano-sedimentary succession of about 400 m thickness. It includes a variety of welded and non-welded ignimbrites, lapilli-tuff fallout deposit, coherent lava, sedimentary mass flow deposit and fluvial sediments, which are grouped into three lithofacies associations, corresponding to different depositional environments. The volcanic activity in the studied area represents successive volcanic eruptions, alternating with phases of quiescence (sedimentary beds). The Ediacaran volcano-sedimentary succession of the Skoura inlier represents an evolution in four stages in a subaerial environment. The geochemical results obtained from Skoura volcanic rocks display high silica-rich composition ranging from dacite to rhyolite. Major and trace elements show high-K calc-alkaline and alkali-calcic to alkaline affinities and reflect an active continental margin signature. In addition, the studied rocks show enriched LILE compared to HFSE with negative Nb-, Ta- and Ti anomalies. This is consistent with a post-collisional setting, documented for the final phase of the Pan-African orogeny. Laser ablation U–Pb zircon dating on three rhyolitic ignimbrites from the base and top of two profiles, yielded ages of 580 ± 7 Ma, 574 ± 14 Ma and 571 ± 4 Ma. These ages compare well with the lower Ouarzazate Supergroup, widespread in the Anti-Atlas, as well as in the High Atlas and with rare exposures in the Meseta domain in northern Morocco.

摩洛哥高图集中的斯科拉岛内层由厚的前寒武纪—古生代组成。它在Aguerzega村附近的西部显示了约400 m厚的火山沉积带。它包括各种焊接的和非焊接的火成岩，lapilli-tuff沉积物，相干熔岩，沉积质流沉积物和河流沉积物，它们被分为三个岩相组合，分别对应于不同的沉积环境。研究区的火山活动代表了连续的火山喷发，并处于静止期（沉积床）。斯科拉内陆的埃迪亚卡拉火山-沉积沉积演替代表了在地下环境中四个阶段的演变。从斯科拉火山岩获得的地球化学结果显示，富含高硅石的成分从菊苣到流纹岩不等。主要元素和痕量元素显示出高K钙碱性和碱钙至碱性亲和力，并反映了活跃的大陆边缘特征。此外，与HFSE相比，Nb-，Ta-和Ti异常为负值，与HFSE相比，研究岩石显示出丰富的LILE。这与在泛非造山运动最后阶段记录的碰撞后环境一致。激光烧蚀U–Pb锆石位于两个剖面底部和顶部的三个流纹状火成岩上，年龄分别为580±7 Ma，574±14 Ma和571±4 Ma。这些年龄与较低的瓦尔扎扎特超级群体相比较，后者在反阿特拉斯，高阿特拉斯中广泛分布，并且在摩洛哥北部的梅塞塔地区极少见。
