Eastward subduction has resulted in successive under-thrusting with tectonic emplacement of the turbidites above the subduction zone to form the Indo-Burman Ranges of western Burma. The ranges are separated from the Eastern Highlands of Burma by the Central Lowlands.In Scotland, the Upper Ordovician and Silurian turbidite sequences of the Southern Uplands are comparable to those of the Indo-Burman Ranges; the Midland Valley and the Grampian Highlands, respectively, are similar to the Central Lowlands and the Eastern Highlands.The development of the Midland Valley and the Southern Uplands can be explained by analogy with the Burma orogen. Both orogens show a similar history of sedimentation, igneous activity, and deformation over a period of 100 m.y., but in Scotland, the equivalent events took place about 400 m.y. earlier than in Burma. There is no known equivalent in Burma of the Early Ordovician Grampian orogeny in Scotland.Our comparison suggests that mineralization similar to that in the Burman volcanic arc should be present in andesite of the Sidlaw anticline.
