This is the alga Rhabdospheara clavigera whose exoskeletons make up most of the chalk of the White Cliffs of Dover and the Ulster White Limestone. The tests (shells) of plankton like these are built from nanocrystals of calcium carbonate.

This is the Mullet Gneiss. It is a unit of the Annagh Gneiss Complex at Annagh Head, on the Belmullet Peninsula, Mayo. These are some of the oldest rocks in Ireland, dated to c.1780Ma.
This large block, weighing an estimated 2 tons, has been tossed up on the headland by the force of storm waves.

The Serpent Rocks. A carpet of prostrated Rugose Corals exposed in the Carboniferous (360-286 Ma) Glencar limestones at Stredagh, Co. Sligo.
They may have been thrown down by a violent storm event in a shallow tropical sea. At this time Ireland was at about the latitude that the Azores are now.

There is no need to roll out the red carpet at Daxia in China’s Gansu Province. The jaw-dropping rocky landscape is naturally red from a build-up of sandstone over many millions of years, while the rainbow effect comes from colourful mineral deposits. Sandstone and red mineral deposits were compressed into multi-coloured layers of rock. Movement of the giant plates that form Earth’s crust pushed, cut, and folded the layers. The name Danxia means “rosy clouds” in Chinese. http://www.geologypage.com/2016/02/zhangye-danxia-national-geological-park.html

Buddhist devotees pray at a gold-covered rock topped by a small pagoda on Mount Kyaiktiyo in Mon state, Myanmar. Legend has it that the rock is perched on a strand of the Buddha’s hair.
