Abstract

[Extract] The NE-trending Ogcheon Orogenic Belt is regarded as forming mainly during progressive NW-SE bulk shortening and/or thrusting. However, this model does not readily explain anomalous geological relationships such as the NW-SE orogenic trend in the northeastern end of the belt, variable dips of NE-SW-striking foliations and contradictory structural youngings across the belt. 3-D microstructural analysis combined with measurement of foliation inflexion/intersection axes preserved in garnet porphyroblasts (FIA, e.g. Bell et al., 1998), using a series for each garnet-bearing schist sample, have revealed a sequence of several sets of foliations preserved in porphyroblasts and/or in the matrix along and across the Ogcheon Orogen. This structural framework includes early composite foliations resulted from NE-SW shortening and crenulation cleavages resulted from NE-SW shortening (Lee, 1999).
