Thallium as a tracer of fluid-rock interaction in the shallow Mariana forearc. In the serpentinite that consisted of various types of serpentine, the extent of dissolution and early reaction rates were greater than in the partially serpentinised dunite. Low seismic velocities, high Vp/Vs ratio and strong S-waves anisotropy characterize serpentine minerals. Conse-quently, the presence of serpentine results in strong localization of strain into weak, narrow shear zones with low flow stresses, and cold thermal structures [e.g., Wada These crystals are so named because they tend to appear serpent-like. Furthermore, research has focused on using serpentine (Mg 3Si 2O 5(OH) 4) as the starting material because it is much more abundant and accessible than the .

In the presence of denser material, its buoyancy can mobilize upwelling masses and aid exhumation. The fibrous serpentine is the vein like mineral between the orthopyroxene and olivine. The word serpentine refers to the mottled, snakelike pattern sometimes seen on the rock. Tectonic exhumation exposes peridotite to aqueous solutions and, because peridotite is unstable in the presence of H 2 O over a wide range of temperatures and pressures, it undergoes a series of dissolution-precipitation and redox reactions to form serpentinite. Serpentinite is a dense, dark green rock that can contain asbestos.
