Schematic section through the Indo-Burma Ranges (IBR) showing three tectonic units (see Fig. 1B for the location of this section) and their detrital zircon U-Pb age spectra. The Kaladan Fault was the boundary separating two different types of age spectra. (A) Section of the IBR showing three tectonic units and their boundaries (modified from Maurin and Rangin, 2009 and Y. Wang et al., 2014c). The Neogene belt is characterized by a thin-skinned structure with open folds above a basal detachment, whereas the Paleogene belt comprises tight-isoclinal folds and thrusts.

Schematic illustrations of the tectonic amalgamation of India and Burma (modified from Xiao et al., 2013). This figure is focused on the southern part of the Indo-Burma amalgamation zone, and the northeastern promontory of the Indian subcontinent is not reconstructed. (A) When the Boka Bil Formation was deposited (ca. 10 Ma), there was an oceanic basin between the Indian subcontinent and the Burma plate, so that the Boka Bil Formation only received sediments from the Indian subcontinent and the Trans-Himalayan arc. The suture separating the upper plate and the lower plate was the basal surface of the Paleogene accretionary prism of the Burma plate. The geomorphology of the western Burma plate is modified from Licht et al. (2018). (B) When the amalgamation occurred (ca. 2.4–3.9 Ma), some sediments were derived from the Indian subcontinent and the Trans-Himalayan arc, but also some from the Burma plate, which were deposited in the Tipam Formation. The suture of Indo-Burma amalgamation was the basal surface of the previous accretionary prism, which separated the Burma affiliated units from the Indian affiliated units. Green curve arrows mean detritus derived from the Indian subcontinent and orange curve arrows mean detritus from the Burma plate. Fm.—Formation; Gp.—Group; IBR—Indo-Burma Ranges.

Scenarios for development of Sagaing fault (SF), Myanmar, if it was initiated in mid-Oligocene, as indicated by North Minwun Basin (NMB) deposition. A: Scenario 1, simultaneous activity of SF and Shan Scarp shear zone to east. B: Scenario 2, West Sagaing fault (a) is northern extension of Panluang fault (PF). Scenarios 1 and 2 follow same evolution in C–F. C: 27–15 Ma: Central Basin has onlapped and covered old ranges of Wuntho-Popa arc. Northward translation of West Burma terrane, with dextral transpression causing shortening in Indo-Burma Ranges. D: 15–10 Ma: Indo-Burma Ranges run up against shortening within India plate (Shillong area, Himalayas), and fault ‘a’ becomes inactive as it is bent, causing strand ‘b’ to develop. Jade belt uplift (JBU) is exhumed. E: 10–5 Ma: Dextral motion switches from west side of North Minwun Basin (NMB) to east side when strand ‘b’ becomes active. F: Present-day setting. EHS—East Himalayan syntaxis; H—Hukawng Basin; Him—Himalayas fold-and-thrust belt; IYSZ—Indus-Yarlung suture zone; PF—Panluang fault; SF—Sagaing fault; SP—Shillong Plateau; SSSZ—Shan Scarp shear zone; STD—South Tibet detachment; W-P—Wuntho-Popa region; a,b,c—strands of Sagaing fault zone, where a—West Sagaing fault, d and e—spays of the Panluang fault.
