摘要
Some marked geological evidences suggest that there exists a deep-seated ductile thrust belt which leads rock melting to form granite in Litian district, SW Fujian, China. Following thrusting event, the lithosphere must have experienced a thermal relaxation which resulted in the cooling and uplifting of the thrust belt. Since the fission track of zircon and apatite have different blocking temperatures, 230℃ and 83℃, respectively,
