A good turnout for Dr. Baxter's workshop. 17 Aug. 2013.
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.

Dolerite dyke at Enniscrone, Co. Sligo showing evidence of glacio-tectonic thrusting of the limestone northward (to the left) along it's horizontal bedding planes. The upper part of the dyke has been shoved c.60m along the beach to the north. Note the crumpling and the brecciation of the top layers of the limestone under the till.

Conodonts lived during the Paleozoic era about 250 to 500 million years ago. They first appeared long before land animals, fish or other creatures with backbones.

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.

Prof. Martin Feely in the quarry workshop explaining the origin, 470 million years ago, of the Connemara Marble Formation.
A fine example of Connemara Marble.

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

Kevin O'Callaghan (in the blue knitted hat) leding a field trip up the Errif River, March 2019.
A 19th century lead and silver mine in the Sheeffry Hills, S. county Mayo that we visited in March 2019. This small mine, sometimes called Tawnycrower mine, was developed along a shear zone dipping at 60-70 degrees NE-SW in grey Ordovician grits and slates. Judging by the small scale of the workings it appears not to have been very profitable. Irish National Grid ref. L 913692.
