| Abstract: | Remanent magnetization of the low-grade metasediments (272 specimens/131 samples from 26 sites), which constitute the Nawakot and Kathmandu Complexes in the northwestern part of the Mahabharat synclinorium, is described. Alternating field (AF) and thermal (TH) demagnetization experiments reveal stable secondary magnetization resting in hematite and represented by normal and reverse polarities. The secondary remanence is of prefolding origin in the rocks from the Nawakot Complex while it post-dates major folding in those from the Kathmandu Complex. The directions are consistent with near-equatorial shallow paleolatitudes. The secondary remanence is interpreted to indicate the occurrence of a series of events, i.e. reheating and/or metamorphism, nappe emplacement and folding in this area at the onset or shortly after the early Eocene India-Eurasia collision. |
