Airborne magnetic data compared to petrology of crustal scale shear zones from southern Madagascar: A tool for deciphering magma and fluid transfer in orogenic crust,

Martelat, J.-E. Randrianasolo, B. Schulmann, K.

The southern part of Madagascar consists of a granulitic metamorphic belt with a complex Proterozoic shear zone network. Aeromagnetic maps reveal sharp magnetic spatial gradients, especially across shear zones. All shear zones are associated with high magnetic values, except one, the Beraketa shear zone. Based upon relationships between rock...

Garnet crystal plasticity in the continental crust, new example from south Madagascar

Martelat, Jean-Emmanuel Malamoud, K. Cordier, P.

Garnet (10 vol.%; pyrope contents 3444 mol.%) hosted in quartzofeldspathic rocks within a large vertical shear zone of south Madagascar shows a strong grain-size reduction (from a few cm to similar to 300 mu m). Electron back-scattered diffraction, transmission electron microscopy and scanning electron microscope imaging coupled with...
