geophysics - What is a massif and what differentiates it from other . . . 11 Wikipedia says that a massif is "a section of a planet's crust that is demarcated by faults or flexures " It goes on to list mountain-like objects Is it not true that most mountains are created by faults or flexures? What is it that distinguishes a massif from any other mountain or group of mountains?
What is meant by Massif? - Earth Science Stack Exchange 3 A massif is an undisturbed solid rock mass, which is demarcated by e g faults Massifs keep their internal structure and are displaced as a whole Only mountains of mountain ranges fulfilling this criteria are called massifs Share Improve this answer Follow answered Aug 20, 2018 at 15:25 JulPal 744311 Add a comment
Olympus Mons sized volcano on Earth? Of course, as they state, the identification of Tamu Massif as a Olympus Mons sized megavolcano suggests that there have been more such megavolcanoes in Earth's early history, most of course would be eroded, lost to tectonic processes etc
geology - Why does a subduction zone produce a serpentinization diapir . . . The last sentence of the abstract of "Tertiary uplift history of the Troodos massif, Cyprus", AHF Robertson says: The dominant driving force may have involved the liberation of water from a subduction zone dipping northward beneath Cyprus
Large scale structures in the Sahara – what are they? These features are created by the wind You will note that the upper left portion has a small dark spot This is known as Waw al-Namus, or the "Oasis of Mosquitoes " It has a path of material in the same curved manner as the surrounding features you mention From the link provided below: However, Waw al-Namus and its plume are not the only "wind records" in the area As you utilise higher
How long does a stratovolcano live? - Earth Science Stack Exchange The monts Dore massif had the Guéry volcano between 3 and 1 5 Ma (it lived 1 5 million years), then the Sancy volcano between 1 2 and 0 2 Ma (1 million years) Further south is Cantal, which used to be Europe's largest volcano and was active between 13 and 3 Ma, although its two main phases were 9–7 Ma (paleo Cantal) and 7–5 5 Ma (neo Cantal)
Why are the supposed-to-be results of collision and or subduction . . . This formed many mountains that still exist today, in Europe (French Massif Central, Bohemian Massif ) or in North America (Appalachian) Breaking up the supercontinent doesn't mean that you erase the mountains that were formed when the supercontinent formed So even if plates move away, you keep old mountains
Origin of the continents - Earth Science Stack Exchange Again, not to attempt to diminish your thinking - but I think you are wildly underestimating the vast span of time that a billion years represents in terms of the Earth's secular evolution It is a quarter of all of geologic time You could easily say it's just as much of a coincidence that the Ediacaran explosion coincided with the disappearance of massif anorthosite from the rock record in
