Description / Table of Contents:
This volume provides a synopsis of current research on volcanic processes, as gained through the use ofpalaeomagnetic and rock magnetic techniques. Thermoremanent magnetization information provides apowerful means of deciphering thermal processes in volcanic deposits, including estimating the emplacementtemperature of pyroclastic deposits, which allows us to understand better the rates of coolingduring eruption and transport. Anisotropy of magnetic susceptibility and anisotropy of remanence areused primarily to investigate rock fabrics and to quantify flow dynamics in dykes, lava flows, and pyroclasticdeposits, as well as identify vent locations. Rock-magnetic characteristics allow correlation of volcanicdeposits, but also provide means to date volcanic deposits and to understand better their cooling history.Because lava flows are typically good recorders of past magnetic fields, data from them allow understandingof changes in geomagnetic field directions and intensity, providing clues on the origin of Earth's magneticfield.
