New book "The Use of Palaeomagnetism and Rock Magnetism to Understand Volcanic Processes"
*****************************************************************************************************
On behalf of the Editors, I would like to announce the recent publication of the new book "The Use of Palaeomagnetism and Rock Magnetism to Understand Volcanic Processes" (SP396) of the Geological Society of London (GSL Special Paper 396). This is also the first in a series of special publications GSL will publish with IAVCEI on volcanological topics. I understand that GSL provides some financial support to IAVCEI from this series.
This volume provides a synopsis of current research on volcanic processes, as gained through the use of palaeomagnetic and rock magnetic techniques. Thermoremanent magnetization information provides a powerful means of deciphering thermal processes in volcanic deposits, including estimating the emplacement temperature of pyroclastic deposits, which allows us to understand better the rates of cooling during eruption and transport. Anisotropy of magnetic susceptibility and anisotropy of remanence are used primarily to investigate rock fabrics and to quantify flow dynamics in dykes, lava flows, and pyroclastic deposits, as well as identify vent locations. Rock-magnetic characteristics allow correlation of volcanic deposits, 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 understanding of changes in geomagnetic field directions and intensity, providing clues on the origin of Earth’s magnetic field.
Best regards,
Editors
