The tectonic evolution of Antarctica [PDF]

open access: yes, 1977
Five tectonic provinces; three volcanic provinces (each characteristic of a particular set of tectonic conditions) and a Precambrian shield, are outlined and described, in an attempt to illustrate the tectonic evolution of Antarctica. Evidence is presented for at least three structural stages in the development of the Precambrian shield, though it is ...

Precambrian tectonic evolution of Earth: an outline [PDF]

open access: yes, 2021
Space probes in our solar system have examined all bodies larger than about 400 km in diameter and shown that Earth is the only silicate planet with extant plate tectonics sensu stricto.

The Tectonic Evolution of Asia [PDF]

open access: yesGeophysical Journal International, 1997
Asia is the youngest continent on our planet and has been assembled largely over the past 400 m.y. In the past decade, following rapid developments on the economic front and political transformations in Asia, Earth science research has continuously become more important for both natural resources evaluation and hazards reduction. Consequently, more and

Reconstructing the Late Palaeozoic – Mesozoic topographic evolution of the Chinese Tian Shan: available data and remaining uncertainties [PDF]

open access: yesAdvances in Geosciences, 2013
The topographic evolution of continents and especially the growth and dismembering of mountain ranges plays a major role in the tectonic evolution of orogenic systems, as well as in regional or global climate changes.

Tectonics and human evolution [PDF]

open access: yesAntiquity, 2006
The authors propose a new model for the origins of humans and their ecological adaptation. The evolutionary stimulus lies not in the savannah but in broken, hilly rough country where the early hominins could hunt and hide. Such ‘roughness’, generated by tectonic and volcanic movement characterises not only the African rift valley but probably the whole

Cenozoic Plate Tectonic Reconstructions and Plate Boundary Processes in the Southwest Pacific [PDF]

open access: yes, 2005
The Australia-Pacific-Antarctic plate circuit has long been a weak link in global plate reconstruction models for Cenozoic time. The time period spanning chron 20 to chron 7 (43-25 Ma) is particularly problematic for global plate models because seafloor

The tectonic evolution of central and Northern Madagascar and its place in the final assembly of Gondwana [PDF]

open access: yes, 2002
Copyright © 2002 by The University of Chicago. All rights reserved.Recent work in central and northern Madagascar has identified five tectonic units of the East African Orogen (EAO), a large collisional zone fundamental to the amalgamation of Gondwana ...

The evolution of plate tectonics [PDF]

open access: yesPhilosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2018
To understand how plate tectonics became Earth's dominant mode of convection, we need to address three related problems. (i) What was Earth's tectonic regime before the present episode of plate tectonics began? (ii) Given the preceding tectonic regime, how did plate tectonics become established?

Influence of the Duration of Tectonic Evolution on Organic Matter Pore Structure and Gas Enrichment in Marine Shale: A Case Study of the Lower Silurian Longmaxi Shale in Southern China

open access: yesFrontiers in Earth Science, 2022
The exploration and development of the shale in the Lower Silurian Longmaxi Formation in the Chongqing area has shown that gas production here is commercially viable.

Geochemistry and tectonic development of Cenozoic magmatism in the Carpathian–Pannonian region [PDF]

open access: yes, 2011
This review considers the magmatic processes in the Carpathian–Pannonian Region (CPR) from Early Miocene to Recent times, as well as the contemporaneous magmatism at its southern boundary in the Dinaride and Balkans regions.
