San Marino	Country

San Marino, officially the Republic of San Marino, is a micro country (61.19km²) entirely surrounded by Italy on the northeastern side of the Apennines.

San Marino is divided into nine municipalities, known as "castelli": San Marino (the capital), Acquaviva, Borgo Maggiore, Chiesanuova, Domagnano, Faetano, Fiorentino, Montegiardino, and Serravalle.

In the territory of the Republic of San Marino, a peculiar geological feature of the external part of the Northern Apennines is exposed, the so-called "Coltre della Val Marecchia"(Val Marecchia allochthonous unit), consisting of a geological body formed of stacked slivers of oceanic crust as Ligurian rocks with the overlying Epiligurian sedimentary cover (allochthonous and semi-allochthonous structural position in the orogen, respectively).

It includes the Epiligurian San Marino Formation, whose deposition took place in a platform environment during the Miocene (Upper Burdigalian).

This formation presents at the bottom shallow marine deposits with biocalcirudites, passing into massive organogenous limestones and at the top into calcarenites with oblique stratification and increasing in the siliciclastic component.

The "San Marino Sandstones" are whitish and yellowish calcirudites, rich in bryozoans, corals, echinoids, and bivalves, with a minor quartz-feldspar siliciclastic component and with scarce carbonatic cement giving the rock a very high porosity. In the Monte Titano area, these rocks have been the object of an intense quarrying activity and local stoneworking since the stonemason Saint Marinus, a native of the island of Arba (presently Rab) in Dalmatia, took refuge there during the Diocletianic Persecution.
