Information - MPRG16 The magnetic field of the lithosphere: implications for tectonics and geology
Event Information
Increasingly accurate and high resolution data from satellites, air
borne and ground based surveys have been routinely used to produce
magnetic anomaly maps of the lithosphere. Satellite derived anomaly maps
provide complementary information to those derived from the air borne
surveys, in the sense that they sample the long wavelength components
(mainly from the lower crust) more accurately. The new high-degree
lithospheric field models allow crustal structures to stand out more
prominently in the observed maps. Subduction zones so prominent in these
global magnetic anomaly maps can improve significantly the understanding
of dynamics of the lithosphere at the boundary of the oceanic subducting
plate beneath continents. The session solicits contributions that reveal
composition and structure of the Earth’s crust, in particular of the
lower crust, reveal tectonic boundaries lay hidden beneath the young
sediments, estimating the depth to Curie isotherm and modelling the
subduction zones and spreading magnetic anomalies over the oceanic
regions. The session also welcomes new methodologies used to model the
magnetic anomalies using high resolution aeromagnetic and satellite
survey data to be presented. Any other contribution relating to
application of magnetic field in geological interpretation is welcome.
