The Rayner Complex of East Antarctica and the Eastern Ghats Province (EGP) of India are thought to have been contiguous in past supercontinents like Rodinia and Gondwana. These terranes have been correlated on the basis of similar granulite facies metamorphic imprints and isotopic age data that testify to Grenvillian (1100-900 Ma) and Pan-African (650-450 Ma) thermal signatures. The Grenvillian granulite facies metamorphic event is generally thought to represent collision between Antarctica and cratonic India, but the precise location of the Indo-Antarctic suture is disputed. The intensity of Pan-African age geological imprints is also variable in both continents, and their significance remains unclear. In this review, we correlate structural, metamorphic and geochronological data in both terranes and parts of their bounding cratons, and suggest that the Ruker Terrane and Rauer Group in Antarctica were continuous with the Rengali Province in India. Together with the established correlation between the EGP and the Rayner Complex, this implies that cratonic India along with the EGP-Rayner amalgam collided with the Archaean Ruker Terrane (part of the Crohn craton) at ~520 Ma along the southern Prince Charles Mountain in East Antarctica. This suture is distinct from the Grenvillian suture between EGP-Rayner and cratonic India.

南极洲东部的雷纳复合体和印度的东高止山脉 (EGP) 被认为在罗迪尼亚和冈瓦纳等过去的超大陆中是连续的。这些地体已根据类似的麻粒岩相变质印记和同位素年龄数据进行了关联，这些数据证明了 Grenvillian (1100-900 Ma) 和泛非 (650-450 Ma) 热特征。Grenvillian麻粒岩相变质事件通常被认为代表南极洲和克拉通印度之间的碰撞，但印度-南极缝合线的确切位置存在争议。泛非时代地质印记的强度在两大洲也各不相同，其意义尚不清楚。在这篇综述中，我们将地体及其边界克拉通部分的构造、变质和地质年代数据相关联，并建议南极洲的 Ruker Terrane 和 Rauer Group 与印度的 Rengali 省相连。连同 EGP 和 Rayner 杂岩之间已建立的相关性，这意味着克拉通印度连同 EGP-Rayner 汞齐在约 520 Ma 沿东部查尔斯王子山南部与太古宙 Ruker Terrane（克罗恩克拉通的一部分）相撞南极洲。这种缝合线不同于 EGP-Rayner 和克拉通印度之间的 Grenvillian 缝合线。这意味着克拉通印度与 EGP-Rayner 汞齐在约 520 Ma 沿南极洲东部查尔斯王子山南部与太古宙 Ruker Terrane（克罗恩克拉通的一部分）相撞。这种缝合线不同于 EGP-Rayner 和克拉通印度之间的 Grenvillian 缝合线。这意味着克拉通印度与 EGP-Rayner 汞齐在约 520 Ma 沿南极洲东部查尔斯王子山南部与太古宙 Ruker Terrane（克罗恩克拉通的一部分）相撞。这种缝合线不同于 EGP-Rayner 和克拉通印度之间的 Grenvillian 缝合线。
