serpentinize /ˈsəːp(ə)ntɪˌnʌɪz /(also serpentinise) verb [with object] GeologyConvert into serpentine: (as adjective serpentinized) partially serpentinized olivine...- Most samples are very altered, with olivines and orthopyroxenes being strongly serpentinized.
- It is clear nevertheless that transforms are sites where deep-seated rocks, such as serpentinized peridotite (derived from the upper mantle), are relatively common.
- The lowermost rocks are serpentinized dunite and harzburgite, which are best exposed in the NE of the ophiolite.
Derivativesserpentinization /ˌsəːp(ə)ntɪnʌɪˈzɛɪʃ(ə)n/ noun ...- Once extension of the adjacent crust ceases, fluid penetration through the crust is hindered and active serpentinization beneath the continental crust ceases.
- It should be noted that these values represent a minimum, as both igneous additions to the crust and mantle serpentinization can generate additional ‘crust’ (in terms of density and hence subsidence behaviour).
- If the P detachment is associated with the onset of serpentinization, the switch from symmetrical to asymmetric (locally simple shear) extension may also be related to the onset of mantle serpentinization.
