Baikal Rift Zone
The Baikal Rift Zone is the largest active continental rift system in Eurasia, a roughly 2,000 km network of basins in southeastern Siberia that contains Lake Baikal and still opens a few millimeters per year.
Continental rift
A continental rift is a nascent plate boundary along which extension thins the lithosphere, forming elongate zones of faulting and volcanism that may open a new ocean basin.
Half-graben
A half-graben is an asymmetric area of subsidence controlled by hanging-wall subsidence above a single basin-margin normal fault, and is the most common structure in syn-rift settings, typically 25 to 100 km long.
Metamorphic core complex
A metamorphic core complex is a domal geological structure where deep metamorphic and granitic rocks are brought to the surface by extension on a low-angle detachment fault.
Rhine Graben
The Rhine Graben is a 300-km-long rift valley along the Rhine between Basel and the Rhenish Massif, forming the central segment of the European Cenozoic Rift System.
Rift valley
Rift valley: an elongated trough formed where lithosphere stretches between normal faults, as in the East African Rift, Baikal Rift, and Rhine Valley; some rifts become ocean basins, others fail and stay dormant.
Rio Grande Rift
The Rio Grande rift is a north-south continental rift where the crust has stretched in east-west extension, running from central Colorado through New Mexico into west Texas and northern Mexico.
