Resumen:
Apaleomagnetic study was carried out in 28 sampling sites on volcanic andvolcaniclastic rocks of the Los Menucos Complex, outcropping in the NorthPatagonian Massif, Argentina. Preliminary results allow determining that mostof the units are carriers of high quality magnetic remanences, defining theComplex as a potential source of reference paleomagnetic pole for the Triassic.At least two acquisition events were recognized, an older one linked to apredominantly reverse geomagnetic field and another younger exclusively normal,recorded in 16 and 11 sites respectively.
