PROJECT
DESCRIPTION
The objective of the project GLImER is to conduct a global survey of
lithospheric interfaces using converted teleseismic body waves. Data from
permanent and temporary seismic networks worldwide are processed automatically
to produce global maps of key interfaces (Moho, intra-lithospheric interfaces,
lithosphere-asthenosphere boundary). The seismic results are interpreted in
conjunction with constraints from complementary fields of the earth sciences
such as tectonics, geodynamics, petrology, and geochemistry. This provides a
unique view of how the properties of these interfaces vary between different
tectonic environments and thus how the interfaces relate to geological
processes at work in these various environments. The results will be
distributed to the scientific community in the form of data products through a
web-based application.
