Neoproterozoic metasedimentary rocks in the foreland domains of the Kaoko–Dom Feliciano–Gariep orogenic system record sedimentation from the breakup of Rodinia to the amalgamation of Gondwana, and thus provide ideal subjects for investigation of the mutual pre-orogenic positions of rifted margins of the African and South American cratonic blocks. U–Pb isotopic dating of zircon in the Brusque Complex of the northern Dom Feliciano Belt, Brazil, provides new constraints on the timing and sources of Neoproterozoic sedimentation along the eastern margin of the Luis Alves Craton. The minimum age of sedimentation is constrained by a U–Pb zircon age of 811 ± 6 Ma from a dyke cross-cutting the Brusque Complex. U–Pb detrital zircon analysis reveals two distinct groups: one with ages ca. 2.2–2.0 Ga consistent with erosion of the adjacent Luis Alves Craton, and another with ages ca. 2.1–1.8 and 1.6–1.0 Ga consistent with erosion of Paleoproterozoic to Mesoproterozoic igneous provinces and/or supracrustal sequences at the edge of the Congo Craton. The age distributions match with analogous rocks of the central Dom Feliciano Belt and the Kaoko Belt, and show similarities with the Gariep Belt, suggesting deposition in a system of coeval and spatially related paleobasins around the time of Rodinia breakup. The absence of Neoproterozoic detrital zircon close to the age of sedimentation suggests deposition in an intracontinental rift or passive margin. A third group contains a significant proportion of Neoproterozoic ca. 670–560 Ma zircon, suggesting similarities with the adjacent Itajaí Basin syn-orogenic foreland sedimentary rocks. This indicates that foreland basin sediments were partly tectonically interleaved with the pre-orogenic metasediments of the Brusque Complex during late-stage orogenic deformation. The findings support an intracontinental rifting model for the formation of the Kaoko–Dom Feliciano–Gariep basin system. The data further indicate that the Luis Alves Craton was in close proximity to the Congo Craton, and likely with the Nico Pérez Terrane and the Kalahari Craton, at the onset of Tonian rifting and the breakup of Rodinia.

Kaoko-Dom Feliciano-Gariep造山系统前陆区域的新元古代准沉积岩记录了从罗迪尼亚解体到冈瓦纳合并的沉积，因此为研究非洲裂谷边缘的相互造山前位置提供了理想的对象和南美克拉通块。巴西北部Dom Feliciano带北部Brusque复杂区中锆石的U–Pb同位素定年，对路易斯阿尔维斯克拉通东缘新元古代沉积的时间和来源提供了新的限制。最小的沉积年龄受堤横切布鲁斯克复合体的U–Pb锆石年龄811±6 Ma的限制。U–Pb碎屑锆石分析显示了两个不同的组：一组具有大约年龄。2.2–2.0 Ga与相邻的路易斯·阿尔维斯·克拉顿（Luis Alves Craton）的侵蚀相一致，另一个年龄约。2.1–1.8和1.6–1.0 Ga与刚果元克拉通边缘古元古代至中元古代火成岩省和/或壳上层序的侵蚀相一致。年龄分布与中部Dom Feliciano带和Kaoko带的类似岩石相匹配，并与Gariep带表现出相似之处，这表明在Rodinia解体前后，该沉积是与古空间和空间相关的古生物的系统。接近沉积年龄的新元古代碎屑锆石的缺乏表明沉积在陆内裂谷或被动缘。第三类包含相当比例的新元古代。670–560 Ma锆石，暗示与邻近的Itajaí盆地同造山带前陆沉积岩相似。这表明在后期造山变形过程中，前陆盆地沉积物与布鲁斯克综合体的造山前准沉积物发生了部分构造交织。这些发现为建立高科-唐·费利西亚诺-加里普盆地系统的洲际裂谷模型提供了支持。数据进一步表明，路易斯·阿尔维斯·克拉顿（Luis Alves Craton）与刚果克拉顿（Congo Craton）十分接近，并且有可能与尼科·佩雷斯·特拉内（NicoPérezTerrane）和卡拉哈里·克拉顿（Kalahari Craton）一样，发生于托尼时代的裂谷和罗迪尼亚的破裂。
