A study of the anisotropy of magnetic susceptibility (AMS) has been done at 24 sites in the Tethyan Himalaya Thrust Belt in SE-Tibet. The sites are located in the Triassic slates. Generally Kmin axes are well grouped at the pole of the mesoscopic foliation. Magnetic foliation strikes WNW-ESE but shows different dips south and north of the Dalmar fault: it has intermediate dips toward the south in the northern part and intermediate dips to the north in the southern part of the same fault. We present new magnetic fabric data to better understand the tectonometamorphic history of SE-Tibet, a key area to understand the formation history of the Himalaya-Tibetan Plateau uplift.

Abstract
A study of the anisotropy of magnetic susceptibility (AMS) has been done at 24 sites in the Tethyan Himalaya Thrust Belt in SE-Tibet. The sites are located in the Triassic slates. Generally Kmin axes are well grouped at the pole of the mesoscopic foliation. Magnetic foliation strikes WNW-ESE but shows different dips south and north of the Dalmar fault: it has intermediate dips toward the south in the northern part and intermediate dips to the north in the southern part of the same fault. We present new magnetic fabric data to better understand the tectonometamorphic history of SE-Tibet, a key area to understand the formation history of the Himalaya-Tibetan Plateau uplift.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
