Fieldtrip and science meeting within in the framework of the 85th Italian Geological Society Meeting
(Field leaders: Luca Pandolfi, Riccardo Tribuzio, Michele Marroni and Alessandra Montanini).
The Jurassic ophiolite sequences from the Northern Apennine are considered to represent an ocean-continent transition similar to the modern Western Iberia margin. The field trip will focus on the ophiolitic bodies from the Ligurian-Emilian Apennine, with the aim to provide a complete picture of architecture and pre-orogenic evolution of the Ligure-Piemontese oceanic basin (i.e. the northernmost edge of the western Tethys ocean) and its transition to the Adria continental margin. The sequences from the Internal Ligurian units are characterised by exposure of mantle lherzolites at the seafloor before the emplacement of basaltic flows, lack of the sheeted dyke complex and interlayering of ophiolitic breccias and basaltic flows. In the External Ligurian units, the ophiolitic sequences consist mainly of fertile subcontinental mantle bodies and MOR-type basalt flows, and are locally associated with upper-lower continental crust rocks. The stratigraphic features of the ophiolite sedimentary covers and their evolution before the inception of the Alpine subduction will be also examined.
