pelagic sediment उदाहरण वाक्य
उदाहरण वाक्य
- This is the most common pelagic sediment by area, covering 48 % of the world ocean's floor.
- The formation of the Cordillera Oriental covered the continental platform with pelagic sediments with Precambrian and Paleozoic metamorphic rocks bases.
- This theory holds due to evidence of pelagic sediments and continental crust being subducted in processes known as sediment subduction and subduction erosion respectively.
- It accumulates more rapidly than any other pelagic sediment type, with a rate that varies from 0.3 5 cm / 1000 yr.
- North of 50?south latitude, 86 % of the main basin is covered by pelagic sediments, of which more than half is globigerina ooze.
- Filling spaces in between the pillows in the pillow lava units are dispersed metal oxide sediments that can also be seen as carbonates, volcanic glass and pelagic sediments.
- Subducting slabs are composed of basaltic crust topped with pelagic sediments; however, the pelagic sediments may be accreted onto the forearc-hanging wall and not subducted.

- This is also supported by geological evidence : 200-230 Ma granite in Lincang, near the Changning-Menglian suture, indicate a continent-continent collision occurred there in the Late Triassic; pelagic sediments in the Changning-Menglian-Inthanon ophiolite belt ( between Sibumasu and Indochina ) ranges in age from Middle Devonian to Middle Triassic, while, in the Inthanon suture, in contrast, Middle to Late Triassic rocks are non-pelagic with radiolaran cherts and turbidic clastics indicating the two blocks had at least approached each other by that time; volcanic sequences from the Lancangjiang igneous zone indicate a post-collisional setting had developed before the eruptions there around 210 Ma; and, the Sibumasu fauna developed from a non-marine peri-Gondwanan assemblage in the early Permian, to an endemic Sibumasu fauna in the Middle Permian, and to an Equatorial-Cathaysian in the Late Permian.
