When the MBT initially formed around 10-25 million years ago, [1] it was a system of thrust faults which accommodated stresses from the compression of the continental collision which led to Himalayan uplift. The Main Himalayan Thrust is the root Décollement structure, and results in similar fault system splays such as the Main Himalayan Thrust ...
The Main Himalayan Thrust (MHT) is a décollement under the Himalaya Range. This thrust fault follows a NW-SE strike , reminiscent of an arc, and gently dips about 10 degrees towards the north, beneath the region.

By lithologic criteria, the Main Central Thrust is defined as the boundary between quartzite and phyllite, from the Lesser Himalayan Sequence; and the orthogneiss biotite-rich schist, which belongs to the Greater Himalayan Crystalline complex. [2] [3] By metamorphic isograd, the Main Central Thrust follows the kyanite isograd. Under this ...
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 ...
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.
The Sub-Himalayan Sequence is thrust southwestward in the rate of 10±6 mm/yr along the Main Frontal thrust during the Quaternary. [15] Within the sequence, rocks have been thrust and accreted vastly, forming the Sub-Himalayan Thrust Zone in the southwest Himachal Pradesh (Fig. 3). The unit is bounded by the Krol thrust and Tons thrust on top. [13]
