The Moine Thrust Belt or Moine Thrust Zone is a linear tectonic feature in the Scottish Highlands which runs from Loch Eriboll on the north coast 190 kilometres (120 mi) southwest to the Sleat peninsula on the Isle of Skye. The thrust belt consists of a series of thrust faults that branch off the Moine Thrust itself.
Nd composition changes mark the Main Central Thrust. For example, an average Nd Epsilon value of −21.5 has been reported in the Lesser Himalayan Sequence while an average Nd Epsilon value of −16 has been reported in the Greater Himalayan Sequence. [6] By strain, the Main Central Thrust is defined as a broad zone which a few kilometers thick.

Thrust faults, particularly those involved in thin-skinned style of deformation, have a so-called ramp-flat geometry. Thrusts mainly propagate along zones of weakness within a sedimentary sequence, such as mudstones or halite layers; these parts of the thrust are called decollements. If the effectiveness of the decollement becomes reduced, the ...
The thrust fault was discovered in 1999 and runs about 40 km (25 mi) in three discrete sections from the Puente Hills region in the southeast to just south of Griffith Park in the northwest. The fault is known as a blind thrust fault, as the fault plane does not extend to the surface. Large earthquakes on the fault are relatively infrequent but ...
There are two main types of thrust tectonics, thin-skinned and thick-skinned, depending on whether or not basement rocks are involved in the deformation. The principle geological environments where thrust tectonics is observed are zones of continental collision , restraining bends on strike-slip faults and as part of detached fault systems on ...
A fault zone is a cluster of parallel faults. [ 5 ] [ 6 ] However, the term is also used for the zone of crushed rock along a single fault. [ 7 ] Prolonged motion along closely spaced faults can blur the distinction, as the rock between the faults is converted to fault-bound lenses of rock and then progressively crushed.
A geological map of the Himalaya region. The Main Himalayan Thrust underlies the rock units. Diagram showing a décollement. 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
