ABSTRACT
Rosa et al., 2006). These deposits are the result from the breakdown of adjacent rocky slopes and the accumulation of aggregates along the slopes and their bases, and for this reason they are very heterogeneous. They are made up of fragments of various types of rock, predominantly basalts, with varying size. Some are boulders as large as 2 meters in diameter, more concentrated at greater depths, and some are cobblestones and angular or semirounded pebbles involved in silt-clay-sand.
