What is Melange in geography?
In geology, a mélange is a large-scale breccia, a mappable body of rock characterized by a lack of continuous bedding and the inclusion of fragments of rock of all sizes, contained in a fine-grained deformed matrix. The mélange typically consists of a jumble of large blocks of varied lithologies.
What is melange zone?
Mélange (spelled melange in much English-language literature) describes heterogeneous rock units that contain blocks, typically of hard or structurally competent lithologies, surrounded and supported by a fine-grained matrix of shale, slate, or serpentinite.
What is the meaning of accretionary wedge?
Sediments, the top layer of material on a tectonic plate, that accumulate and deform where oceanic and continental plates collide. These sediments are scraped off the top of the downgoing oceanic crustal plate and are appended to the edge of the continental plate.
How do accretionary prisms form?
Accretionary prisms form at the leading edge of convergent plate boundaries by skimming-off sediments and rocks of the lower plate. The rapid rate of underthrusting of the lower plate may carry rocks to great depths before they can heat up, forming a characteristic type of metamorphic rock called a blueschist.
What forms an accretionary wedge?
An accretionary wedge or accretionary prism forms from sediments accreted onto the non-subducting tectonic plate at a convergent plate boundary. Accretionary complexes are typically made up of a mix of turbidites of terrestrial material, basalts from the ocean floor, and pelagic and hemipelagic sediments.
What is an accretionary wedge quizlet?
Accretionary wedge. a large wedge shaped mass of sediment that accumulates in subduction zones. Here sediment is scraped from the subducting oceanic plate and accreted to the over riding crustal block.
What is an accretionary terrane?
Accreted terranes are the blocks of continental fragments and oceanic islands that have collided with a continent and are now permanently attached. When island arcs collided with other island arcs, rock and sediment were scraped off the top of subducting plates.
Where does most terrane accretion occur quizlet?
Where does most terrane accretion occur? In association with a continental-oceanic subduction zone.
What is a super terrane?
Intermontane superterrane The superterranes are larger than any individual terrane. The Intermontane superterrane was being accreted to North America by the end of the Jurassic Period, as North America moved west over the subducting oceanic plate.
What is an exotic terrane quizlet?
define an exotic terrane. defined as. -being bounded by faults. -having rocks, structures and fossils. -embedded within continents are pieces of crust that have a different geologic history than adjacent rocks.
