Аннотация:The magnetic signature of subsurface geology is
crucial for understanding the crustal structure and its composition.
Marine and aeromagnetic surveys deliver low-resolution regional
coverage with a high cost. Ground surveys by walking are much
cheaper, yet their coverage is limited to site surveys. The quantitative
integration of varying datasets is one of the main
challenges of the magnetic method. These datasets differ in the
type of acquisition equipment used, geographical scale, elevation
of measurement stations and their spacing, physical limitations in
the field, borders, and different datum. Here we tackle these
challenges through improving the ground magnetic coverage
extent by bike-mag measurements, and improving and applying
the ‘‘equivalent source technique’’ for integration of all available
data sources, upon their high variability. We constructed detailed
magnetic anomaly maps for the area hosting the Dead Sea
transform (DST) continental plate boundary which intersects the
Harrat Ash-Shaam volcanic field. Despite the complex conditions,
our new magnetic maps (intensity and reduced-to-pole, RTP)
show a remarkable agreement with independent geological, geophysical,
geochronological and geomorphological evidence. The
new magnetic results suggest that the magnetic anomalies define
subsurface basaltic bodies, including an E–W elongated body that
crosses the DST within the Kinneret Basin, and a volcanic
eruption center within the Yarmouk River gorge. In addition, the
N-trending DST strand bounding the western Kinarot Basin
crosses the Kinneret Basin diagonally (SW–NE). The consistent
and reliable results allow us to recommend our methods for
suitable regions worldwide.
