Why are such events important for unravelling what happened during Earth's early history? How are some rocks from South Africa providing clues on crust formation on early Earth? Some geologists from Stellenbosch University are investigating.Cutts, KathrynQuest...
[1]Mountain formation is related to plate tectonics. Folding, faulting, volcanic activity, igneous intrusion and metamorphism are all parts of the orogenic process of mountain building.[2]The understanding of specific landscape features in terms of the underlying tectonic processes is calledtectonic ...
Earth science, as one of the six categories of natural sciences, not only explores the origin, evolution, and development trends of the Earth, but also provides scientific knowledge, cognitive approaches, and research methods for human understanding, utilization, and transformation of nature. With th...
An important consequence of this carbonate build-up is that continental rifts and arcs mobilize more carbon through metamorphism (hence why their activity has been linked to greenhouse–icehouse climate cycles during the Phanerozoic36). Thus, an increasing crustal carbonate reservoir could imply a ...

Cupid’s Arrow is a small satellite mission, proposed by JPL to measure noble gases in the atmosphere of Venus (Fig.4). It was selected by the NASA PSDS3 Program and will be based on the VERITAS (Venus Emissivity, Radio Science, INSAR, Topography, and Spectroscopy) mission mothership (Sot...
