Peridotites, serpentinites and peridotites-serpentinites are found along the tunnel as described in Table 1. Peridotite is a magmatic rock. Serpentinite is a metamorphic rock and hydrothermally transformed case of peridotites. Peridotite-serpentinite is a metamorphic rock and half-hydrothermally transformed case of peridotites. These rock formations may be very problematic in most cases in tunneling (Marinos et al. 2006, Clark & Chorley 2014, Glawe & Upreti 2014).
Minerals, rocks, discontinuities and rock mass
Published in Ömer Aydan, Rock Mechanics and Rock Engineering, 2019
Serpentinite is comprised of serpentine minerals. Minerals in this group are formed by a hydration and metamorphic transformation of ultramafic rocks. Serpentinite is formed from olivine via several reactions. It can be easily weathered, resulting in swelling.

Shallow reworking of magmatic zircon grains of latest Neoproterozoic (Timanian) age in serpentinite of the Voykar Massif, Polar Urals: new constraints from U-Pb isotopic data, and first trace elements and Lu-Hf isotopic data

The serpentinite is a black-green, dense, splintered rock with fissures filled with green serpentine minerals, locally showing slickensides. The rock consists mainly of the serpentine mineral antigorite, minor magnetite, and traces of calcite and clinochrysotile (all identified by XRD). Additionally, chlorite, zircon grains, and actinolite were identified in thin sections (see Supplementary Fig. 1b, c). No primary minerals could be found, the original ultramafic rock is completely altered.
