What is Shyok suture zone?
The Shyok Suture Zone (Northern Suture) of North Pakistan is an important Cretaceous-Tertiary suture separating the Asian continent (Karakoram) from the Cretaceous Kohistan–Ladakh oceanic arc to the south.
What is suture zone in geology?
A suture zone is a linear belt of intense deformation, where distinct terranes, or tectonic units with different plate tectonic, metamorphic, and paleogeographic histories join together.
What is ITSZ?
The ITSZ is a suture zone in the Ladakh region and marks the limit of the Indian plate where it collides with the Eurasian plate and is subducted below the latter.
Where do suture zones occur?
Perhaps the most well-known geological suture zone is the Himalayan mountain range formed by the collision of the Indian subcontinental plate and the Asian continental plate (Pichamuthu 1967).
What is Indus Tsangpo suture zone?
The Indus-Yarlung suture zone or the Indus-Yarlung Tsangpo suture is a tectonic suture in southern Tibet and across the north margin of the Himalayas which resulted from the collision between the Indian plate and the Eurasian plate starting about 52 Ma.
What is suture in paleontology?
In structural geology, a suture is a joining together along a major fault zone, of separate terranes, tectonic units that have different plate tectonic, metamorphic and paleogeographic histories. The suture is often represented on the surface by an orogen or mountain range.
What is triple junction in geology?
A triple junction is a point where the three plates, A, B, and C, meet. It is also the intersection of the boundaries between the three pairs AB, BC, and AC. The velocity of any point moving along one of these boundaries will lie on a line in velocity space (Box 3-1).
What is Himalayan frontal fault?
The Main Frontal Thrust (MFT), also known as the Himalayan Frontal Thrust (HFT) is a geological fault in the Himalayas that defines the boundary between the Himalayan foothills and Indo-Gangetic Plain. The fault is well expressed on the surface thus could be seen via satellite imagery.
What is a suture line Ammonite?
The wavy line of intersection between the shell and septum is called the suture line, which is highly diverged among ammonite species; it is a useful index for taxonomical identification8,9,10,11.
Why Himalayas do not have volcanoes?
There are few volcanoes in the Himalayas because there are no subducted plates. It is an earthquake zone, and yes, there are volcanoes, but no eruptions. The geology just doesn’t support it at this time. This is because the earth is an ever-changing landscape.
What happens when 3 tectonic plates meet?
When three plates meet, the boundaries are also bringing together their own motions at the intersection. For convenience, geologists use the notation R (ridge), T (trench) and F (fault) to define triple junctions. For example, a triple junction known as an RRR could exist when all three plates are moving apart.
What is the Indus-Yarlung suture zone?
The Indus-Yarlung suture zone or the Indus-Yarlung Tsangpo suture is a tectonic suture in southern Tibet and across the north margin of the Himalayas which resulted from the collision between the Indian plate and the Eurasian plate starting about 52 Ma. The north side of the suture zone is the Ladakh Batholith of the Karakoram-Lhasa Block.
Is there an Indus Suture Zone in Ladakh?
Geology of Indus suture zone of Ladakh (eds) V C Thakur and K K Sharma (Dehradun: WlHG) 79-97 Shah S K, Sharma M L, Gergan J Tand Tara C S 1976 Stratigraphy and structure of the western part of the Indus suture belt, Ladakh, Northwest Himalaya; Himalayan Geol. 6 534-556
Is the Indus Tsangpo Suture Zone a palaeotectonic zone?
accreted to the Eurasian plate in Mesozoic (Bassoulet et aI 1980;, Thakur 1981; Nicolas et al 1981). In the Indus Tsangpo suture zone, which represents the collision zone between the Indian continent and the Karakoram-Tibet block, the different palaeotectonic regimes have been recognized (figure 4).
What is the Indus palaeosubduction complex?
In the Indus Tsangpo suture zone, which represents the collision zone between the Indian continent and the Karakoram-Tibet block, the different palaeotectonic regimes have been recognized (figure 4). These are Indus palaeosubduction complex,
