Two contrasting parallel tectonic sutures can be recognised through the Yunnan-Thailand region of mainland Southeast Asia; they are sutures of the Devonian-Triassic Palaeo-Tethys Ocean and a Permian back-arc basin. The Changning-Menglian and Inthanon suture zones are regarded as the Palaeo-Tethys Suture Zone. The Jinghong-Nan-Sra Kaeo suture is regarded as a closed back-arc basin. The Sukhothai Zone is no longer treated as a part of the Sibumasu Terrane, but is defined as the core part of the Permian island-arc system developed on the western margin of the Indochina Terrane. Two tectonic events are interpreted from the parallel sutures; a Late Permian collapse of the back-arc basin and a mid-Triassic collision of Sibumasu to the Sukhothai Arc of Indochina (= closure of the Palaeo-Tethys). The Early-early Middle Triassic thermotectonism of Vietnam as linked to the Indosinian orogeny by some authors is incompatible with the suggested timing of Sibumasu collision, but instead it is temporally closer to the back-arc compression of western Indochina.
