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.
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.
