Interest in Alaskan tectonic studies has varied through time as different events have focused attention toward and away from this North American frontier. In 1964 the great Alaskan earthquake focused attention on Alaska, and was a major factor in the establishment of the concept of subduction in the early days of plate tectonics (e.g., Cox, 1973). In the 1980s, the northern Cordillera, including Alaska, was the subject of extensive study using the terrane analysis approach, which spawned a series of new tectonic syntheses (e.g., Coney et al., 1980). These studies primarily focused on the Mesozoic accretionary history of...
