Abstract
The structures of the emerald deposits of the western part of Eastern Cordillera of Colombia (thrusts, ramps, duplexes, tear faults) have be en formed by three deformational events forming a single thrust-tecton ics phase, synchronous with the emerald-forming hydrothermalism. As th is hydrothermalism is Late Eocene-Early Oligocene in age, it is also t he age of the thrust tectonics.
