ABSTRACT The scope of the present contribution is to contrast two different marine environments in two different Greek Islands (Afantou Bay_Rhodes Island and Kissamos Bay – Crete Island), in order to be characterized as marine aggregates environments or not. Marine aggregates (MA) are sands and gravels dredged from the sea bed and are used in: concrete and mortar manufacture, asphalt and coated products, block making, drainage and fill materials, leisure and sport facilities and beach replenishment (BMAPA, 2003). Generally, areas with increased possibilities of presence of Marine Aggregates at the continental shelf are related to: (1) the lithology of the nearest coastal area, (2) the presence of relict deposits and (3) the presence of river mouths. Generally, aggregates depending on their size are divided into: a) coarse aggregates with 63mm
