The main Hercynian suture zone of the collided plates extends from the south side of Brittany to the Massif Central.
To the east it continues into Mongolia and there unites with the circum-Altaid suture zone coming from the west i.e., from the Tien Shan.
The main suture zone, which passes across central Ireland and along the England-Scotland border, separates the two continental blocks that have different sedimentary, igneous, and metamorphic rocks, fossils, and mineralization and different stages of evolution.
The later one collided along a suture zone farther to the north, along the present-day Ma River, during the early Carboniferous and caused a major south-directed deformation that included considerable thrusting.
The earthquake and its aftershocks were the result of thrust faulting (i.e., compression-driven fracturing) in the Indus-Yarlung suture zone, a thin east-west region spanning roughly the length of the Himalayan ranges.
The earthquake's epicentre occurred about 50 miles (about 80 km) north of the Bitlis Suture Zone, a complex geologic region characterized by rock folding and a series of three large northward-dipping thrust faults (a fault type in which older rocks are forced up and over younger ones).
These rocks are most likely equivalent to the ones exposed in the Bentong Raub suture zone.
The Longitudinal Valley in eastern Taiwan marks the suture zone of the two colliding plates.

These strata furnish a record of uplift and paleoenvironmental change in the Indus-Yarlung suture zone during the Oligocene-Miocene.
The latter corresponds to a Precambrian suture zone overprinted by successive extensional tectonics and buried beneath the foreland basin.
