Pre-hecynian Magmatic Activity in the Nappe Zone (External and Internal) of Sardinia:evidences of two Wthin-Plate Basaltic Cycles / Di Pisa, A; Gattiglio, M; Oggiano, Giacomo. - 276:(1992), pp. 107-116.
abstract:
Recent data on stratigraphic and structural relationships among the sequences of the "Nappe Zone" of the Variscan Chain in Sardinia , from Sarrabus to Nurra, have made possible to set in a detailed spatial and temporal frame the pre-Variscan intermedite-basic volcanic activity.
The review of the relatioships between metabasites and coutry rocks , the fabrics analysis, the geochemistry and the structural and palaeogeographic setting , allow to propose a new interpretation of the pre-Variscan tectono-magmatic evolution.
