The Casaglia-Monte della Colonna is one of the best exposed “fossil” mass-transport complex (MTC) cropping out in a foredeep succession exhumed in a mountain chain and represents a unique opportunity to study an internal architecture resulting from the (geologically) simultaneous collapses of an accretionary wedge front, slope, and basin plain deposits. The high variety of internal structures and the different MTC-substratum interactions depend on the geometry of MTC basal contact and the provenance of the remobilized sediments. In the 20 years from our first studies on this MTC, the better condition of some outcrops and the advances in methodological and interpretative tools enable us to provide an update scenario, with more details on the internal structures and a better comprehension of the complex interactions with the substratum.

Abstract
The Casaglia-Monte della Colonna is one of the best exposed “fossil” mass-transport complex (MTC) cropping out in a foredeep succession exhumed in a mountain chain and represents a unique opportunity to study an internal architecture resulting from the (geologically) simultaneous collapses of an accretionary wedge front, slope, and basin plain deposits. The high variety of internal structures and the different MTC-substratum interactions depend on the geometry of MTC basal contact and the provenance of the remobilized sediments. In the 20 years from our first studies on this MTC, the better condition of some outcrops and the advances in methodological and interpretative tools enable us to provide an update scenario, with more details on the internal structures and a better comprehension of the complex interactions with the substratum.File | Dimensione | Formato | |
