In this paper, we discuss and critique existing hypotheses about the geology of Middle-earth in light of current geological theories of planetary formation, mountain building (orogeny) and plate tectonics. We dispute the prevailing tectonic explanation for the major geological features of Middle-earth and Arda on the basis of evidence as yet not fully considered about the formation of the plane...

In this work the central area of Corsica island was studied in order to reconstruct tectono-metamorphic history continental and oceanic high pressure units that occupy structurally deeper levels tectonic stacking Alpine their stratigraphic structural relationship with European margin (Hercynian Corsica). The study includes geological mapping, mesoscale microscale analysis, acquisition chemical ...

Introduction. The once popular idea that changes in planetary volume play an important role in terrestrial orogeny and tectonics [ I ,2] was generally discarded with the acceptance of plate tectonics. It is nonetheless likely that the Earth has been steadily cooling over the last 3-4 billion years [e.g., 3,4], and the global contraction that accompanied such cooling would have led to a secular ...

The change of motion mode multistage active strike-slip faults controls the segmentary types faults, which is seldom studied.Based on high-precision 3D seismic data and principle structural analysis, this paper defines evolution characteristics tp12cx fault in key period identifies segmentation types. Combined with statistical results drilling production width, it demonstrated that different se...

После выявления на Кавказе в начале 70-х годов ХХ века тектонических покровов стало понятно, что последовательность нижне(?) и среднепалеозойских пород древнего ядра Большого Кавказа является тектоно-стратиграфической образует аккреционную колонну. Считалось, современном виде она была сформирована главную фазу герцинского орогенеза представлена несколькими системами покровов. В работах кавказск...
