... chemistry intruded into and were deformed within the Tonalá mylonite belt in the middle to upper crust. The mylonite belt is a crustal-scale shear zone extending along the western margin of the Chiapas Massif for ∼150 km. Deformation is characterized by a dominantly subhorizontal lineation and subvertical...

... was also accompanied by the onset of arc-related magmatism beneath the massif, between ca. 13 and 9 Ma, along the Tonalá shear zone at the Pacific coast. Since ca. 7 Ma, additional but slower cooling and exhumation are indicated along the length of the Chiapas Massif, and arc magmatism has jumped north...

...) , the Tonalá fault has left-lateral displacement, mainly during the middle Miocene. Wawrzyniec et al. (2005) proposed that the Tonalá fault (or Tonalá shear zone, as they called it) may have originated as a dextral transform fault that was later reactivated as a sinistral fault in the Miocene. Authemayou et...
