The Lesser Himalaya (LH) tectonic plate is mainly formed by Upper Proterozoic to lower Cambrian detrital sediments from the passive Indian margin intercalated with some granites and acid volcanics (1840 ±70 Ma [17]). These sediments are thrust over the Sub-himalayan range along the
Accordingly K2 is only in the table below for reference and not shown on the map on this page. The interactive map on this page ranks Himalayan peaks above 7,500 m (24,600 ft) and is more inclusive. A peak has a different definition to a mountain and different authorities may use different definitions of either.
This paradoxically results in divergence which was only incorporated in the theory of plate tectonics in 1970, but still results in net destruction when summed over major plate boundaries. [2] Divergent boundaries are areas where plates move away from each other, forming either mid-ocean ridges or rift valleys. These are also known as ...
The Himalayas consists of four parallel mountain ranges from south to north: the Sivalik Hills on the south; the Lower Himalayan Range; the Great Himalayas, which is the highest and central range; and the Tibetan Himalayas on the north. [16] The Karakoram are generally considered separate from the Himalayas.
Continental-continental divergent/constructive boundary Oceanic divergent boundary: mid-ocean ridge (cross-section/cut-away view). In plate tectonics, a divergent boundary or divergent plate boundary (also known as a constructive boundary or an extensional boundary) is a linear feature that exists between two tectonic plates that are moving away from each other.
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. [1] The fault is well expressed on the surface thus could be seen via satellite imagery.
Map of Earth's principal plates (convergent boundaries shown as blue or mauve lines) The collision between the Eurasian plate and the Indian plate that is forming the Himalayas. [22] [23] The collision between the Australian plate and the Pacific plate that formed the Southern Alps in New Zealand
The northernmost boundary of the Siwaliks Group is marked by the Main Boundary Thrust (MBT), over which the low-grade metasedimentary rocks of the Lesser Himalaya overlie. The Lesser Himalaya also called the Lower Himalaya, or the Midlands, is a thick (about 7 km) section of para-autochthonous crystalline rocks made up of low- to medium-grade ...
