3-DIMENSIONAL SEISMIC CRUSTAL STRUCTURE OF THE MONASHEE HINTERLAND CORE COMPLEX ON THE LITHOPROHE SOUTHERN CANADIAN CORDILLERA TRANSECT

Three-dimensional seismic coverage in an approximately 12 km x 12 km a rea of the southern Monashee metamorphic complex in the south-central portion of the Canadian Cordillera reveals a complex geometry to the M esozoic - early Tertiary contractional Monashee decollement. Data were acquired as part of the Lithoprobe Southern Canadian Cordillera Trans ect where two approximately perpendicular lines intersected on the sou th flank of the Monashee mountains in the hinterland of the Cordillera . Stacks of traces within 100 m x 100 m bins are nominally 6-fold, but range from zero to 108-fold due to the crooked nature of the lines. B oth migrated and unmigrated data have been examined for interpretation , but the highly variable data quality and discontinuous reflectivity cause excessive added noise during the migration process.
