Abstract

The Rio de la Plata and Paranapanema cratons are major constituents of the South American Platform, yet both cratons are predominantly covered by Paleo- to Cenozoic basins. Because of that, much about their geological evolution and tectonic position in different supercontinent cycles is still little known, and most inferences about these paleocontinents is recorded indirectly in their surrounding orogenic systems. This special volume collects 15 novel contributions highlighting recent advancements in uncovering the cratonic blocks and their surrounding orogenic systems, from their ancient evolution to their tectonic significance during the assembly of Gondwana and establishment of the Proto-Pacific active margin. The collected studies span a large geographic extent in South America and African counterparts, and follow a variety of methodological approaches.

拉普拉塔河和帕拉纳帕内马火山口：揭开冈瓦纳西部的神秘面纱

拉普拉塔河和帕拉纳帕内玛大陆架是南美洲地台的主要组成部分，但这两个大陆架主要被古生代至新生代盆地所覆盖。正因为如此，人们对它们在不同超大陆周期中的地质演化和构造位置仍然知之甚少，有关这些古大陆的大部分推论都是通过它们周围的造山系统间接记录下来的。本特辑收集了 15 篇新论文，重点介绍了在揭示板块及其周边造山系统方面的最新进展，从它们的远古演化到它们在冈瓦纳大陆组装和原太平洋活动边缘建立期间的构造意义。所收集的研究跨越了南美洲和非洲对应地区的广大地理范围，并采用了多种方法。

期刊介绍： Precambrian Research publishes studies on all aspects of the early stages of the composition, structure and evolution of the Earth and its planetary neighbours. With a focus on process-oriented and comparative studies, it covers, but is not restricted to, subjects such as: (1) Chemical, biological, biochemical and cosmochemical evolution; the origin of life; the evolution of the oceans and atmosphere; the early fossil record; palaeobiology; (2) Geochronology and isotope and elemental geochemistry; (3) Precambrian mineral deposits; (4) Geophysical aspects of the early Earth and Precambrian terrains; (5) Nature, formation and evolution of the Precambrian lithosphere and mantle including magmatic, depositional, metamorphic and tectonic processes. In addition, the editors particularly welcome integrated process-oriented studies that involve a combination of the above fields and comparative studies that demonstrate the effect of Precambrian evolution on Phanerozoic earth system processes. Regional and localised studies of Precambrian phenomena are considered appropriate only when the detail and quality allow illustration of a wider process, or when significant gaps in basic knowledge of a particular area can be filled.
