The phrase "active margins of" is correct and usable in written English.
It is typically used in geological or geographical contexts to refer to the edges of tectonic plates where significant geological activity occurs, such as earthquakes and volcanic eruptions.
Example: "The active margins of the Pacific Plate are known for their frequent seismic activity and volcanic eruptions."
Alternatives: "dynamic boundaries of" or "tectonically active edges of".
The Late Cretaceous tectonic evolution of NE China reflects a complex history of extensional, contractional and strike-slip deformation as a result of the Mesozoic geodynamics of the active margin of East Asia.
Using published age and paleogeographic constraints, we propose the presence of (1) a major early Paleozoic tectonic boundary that separates the Chinese Altay East Junggar multiple subduction systems of the southern Siberian active margin from those of the northern Tarim; and (2) a major Permian suture zone that separates the Tianshan Beishan from the northern active margin of the Tarim Craton.
New geological mapping and 40Ar 39Ar ages reveal a temporal progression of faulting along a major extensional fault (the Abert Rim fault) at the active margin of the Basin and Range Province in the western U.S. The onset of extensional deformation near Lake Abert coincided with widespread basaltic volcanism.
Pontides are a mountain chain that had been built up as a tectonic unit, which were amalgamated onto active margin of Laurasian Continent.
An incisional biopsy from the active margin of a leg lesion showed several foci of dermal necrosis with dense lymphocytic infiltrate and Langhans-type giant cells consistent with granulomatous inflammation of tuberculosis.
For example, there are seaward-facing benches that are thought to be uplifted marine terraces common to active margins; but the drainage divide of the seaward escarpment shows clear evidence of recent northward migration into the Po foreland, a process consistent with escarpment retreat characteristic of passive or subsiding margins.
Marine Geology and Geophysics scientists study some of the most remote and forbidding parts of our planet, from the active margins beneath the oceans to the polar ice sheets.
The studied area, built up by silty clayey and partly sandy sediments and paleosols, lies on the tectonically active Northern margins of the Pannonian Basin.
The sedimentary architecture of active margin basins, including back-arc basins, is known only from a few end-members that barely illustrate the natural diversity of such basins.
