Comparison with other arc systems suggests that in the fore-arc area of the northern Sunda Arc emplacement of chromite and jadeite-bearing serpentinite melange diapirs and deposition of olistostromes were caused by Campanian collision with a continental fragment since underthrust eastwards beneath the arc. The age and position of east-directed thrusts and associated tin granites in the continental back-arc area implies that thrusting and generation of granites were genetically related to the collision, and that the back-thrusts were coupled to the fore-arc thrusts by a decollement beneath the fore-arc basin and magmatic arc. Subsidence and sedimentation in the fore-arc basin succeeded collision, and rise of the back-arc Shan Plateau possibly resulted from late Cenozoic relaxation of collision-related compressive stress. |
