Thermochronometric Studies of Mountains in Island Arc Settings Based on Fission-track Method: A Review

Abstract

Thermochronometric studies (e.g., fission-track thermo chronometry) on major orogenic belts, such as collision zones and/or cratons have been successfully conducted since 1970s. However, such studies in arc-trench systems were limited so far. According to the development of thermochronology in three decades, the applicability for these regions has been identified. Thus, recent thermochronomet ric studies in an island arc setting have been proceeding. This paper introduces the concept and the current status of thermochronometric studies for mountain building process on arc-trench settings, especially these case studies in island arcs.
