Fission-tracking
WebFission track thermochronology is a geochronologic method that yields the time when rock rose through the 2 to 5 km depth window or ~80°-120°C (for apatite). This low-temperature thermochronometer allows us to collect data at the regional scale to study time-space patterns of mountain building and their uplift or on detailed scales to ... WebJul 14, 2024 · This book is focused on the basics of applying thermochronology to geological and tectonic problems, with the emphasis on fission-track thermochronology. It is conceived for relatively new practitioners to thermochronology, as well as scientists experienced in the various methods. The book is structured in two parts. Part I is devoted …
