Resumen:
This work deals with the structure and emplacement of
the alkaline complex of the Sierra de Rangel, a Cretaceous stock intruding in
Ordovician metamorphic rocks of the Puna region at Salta,
northwest Argentina.
Field structures and magnetic fabrics reveal a complex structure composed by
multiple sheets and feeding chanels. Both, the ascent and the lateral spreading
of magma exploited old fractures in the country rocks.
