Colourful sandstone in Jordan

Colourful sandstone in Jordan with a beautiful offset of layers and an expressively dynamic dark red form that reminds me of a bird flying up into the air.

 Rock formations on Lavezzi Island

Not so far from Bonifacio (Corsica, region of France) there is a little island called Lavezzi, reachable with a boat.
It's an amazing place because of the shapes of its rocks: they are rounded and smoothed, as someone had used an emery paper on them.
There were a lot of nice rock formations so it was difficult to chose a pic from the multitude but I thnk this one gives the idea of what you can find on Lavezzi.

distinctive limestone pavement covering much of the Burren

The distinctive limestone pavement covering much of the Burren is composed of massive blocks of limestone called clints separated by fissures called grikes. Such forms are the result of several Millennia of exposure to the mildly acidic action of rainwater, and are collectively known as karren features.

Grykes on Inis Mór

Grykes on Inis Mór.
The Aran Islands are an extension of the Carboniferous limestone of the Burren. I observed here, beside Dún Aengus, that the most dominant grykes ran from north to south with secondary less developed systems at right angles to it. This photo was taken facing south, where beyond the cliff, on a clear day the coast of County Kerry is visible.

Picture shows a glacial erratic rock through a limestone wall.These erratics were debris carried in to the area by glaciers. When the glaciers melted these rocks were left behind.

The Frasassi Caves, located in central Italy near the town of Genga

The Frasassi Caves, located in central Italy near the town of Genga, are large cave complex spanning some 13 kilometers of known caves. It is estimated that they entire cave system may be upwards of 35 kilometers long. The Frasassi underground caves, extending over 30 km, over 8 different geological levels, represent one of the world's most impressive underground excursions.

The mountain group of Valmontagna and Frasassi is characterised by a folding geological motif, with a wide limestone anticlinal corresponding to the orographic relief, and narrow synclinal which correspond to valleys and plans. Water circulation constituted by river Sentino entered these geological structures, after orogenesis events, helped by faults and “diaclasi”(wide cracks in rocks).

The foreshore shows sections of Lower Devonian rocks - mainly red mudstones, now metamorphosed to slate, siltstones and sandstones

The foreshore shows sections of Lower Devonian rocks - mainly red mudstones, now metamorphosed to slate, siltstones and sandstones which experienced Variscan deformation during the Permo-Triassic age.

It is thought that they were originally laid down in mudflats and floodplains associated with lakes. Some fossil fish remains have been found here and there may have been an occasional connection between these lakes and the nearby sea. The Pleistocene raised beach platform here is backed by a fossil cliff line. The raised beach platform is being cut back by wave action.
