Figure 3-B, from 95 to 87 Ma the mid-ocean ridge stopped spreading and the intra-oceanic thrusting started. Where the left oceanic lithosphere subducted under the right oceanic lithosphere with the Semail Ophiolite, which are accreted at amphibolite facies conditions at the base of the Semail Ophiolite. Figure 3-C, from 87 to 76 Ma the Semail Ophiolite over thrusts the continental lithosphere and is emplaced onto the craton, which are accreted at greenschist-facies conditions at the base of the Semail Ophiolite.
