Day 6 : This is a schist with crenulations in three different directions. In the image they run vertically, top right to bottom left, and on a slightly larger scale top left to bottom right. Unknown locality. Keele collection.
Day 5 : Today’s image shows a type one interference fold or re-folded fold. The rock is the Appin Limestone (or ‘Marble’) from the Late Precambrian Dalradian of Scotland. From Onich in the Scottish Highlands.
Day 4 : Some folds for the rest of the week. This is a kink fold in a mylonite fabric. The mylonite is from the Kvitenut Gneiss Complex of the Hardargevidda Nappe System in Hordaland, S.W. Norway. The rock dates from around 1.65Ga and was deformed during the Caledonian Orogeny …
Day 3 : This is a sample collected on the previous day from the mine spoil heaps at Yewthwaite Comb on the western side of Catbells, Lake District, Cumbria, England. The Lake District is quite heavily mineralised with Ordovician copper mineralisation along east-west faults and Carboniferous lead-zinc veins trending north-south. …
Day 2 : The Lower Ordovician (Tremadocian / Floian [Arenig]) Buttermere Formation is an olistostrome deposit at least 1.5 kilometres thick. The unit, of which this sample is fairly coarse, was believed to have been emplaced as a single massive slumping event in the late Floian. This breccia was found …
Day 1 : In 2010 I endeavoured to photograph a rock every day – project Rock365. How to better this? Wait for a leap year and start Rock366! This the the Buttermere and Ennerdale Granophyre – a granophyric microgranite from the shores of Buttermere in the Lake District. It was …
Rock365 Supplemental : Well, that’s it. Rock365 is complete. I might post the odd interesting rock photo here from time to time but the photo a day project for 2010 has reached an end. I leave you for now with a view of the New Year’s fireworks in Funchal, Madeira. …
Day 365 : Tephra, from behind the church of São Martinho (St. Martin) Funchal, Madeira
Day 364 : A thick succession of basalt lava flows in the cliffs above Curral das Freiras (or Nun’s Valley), Madeira.
Day 363 : The main slope above Funchal is defined by a thick, columnar jointed basalt lava flow that is deeply incised by three main rivers. Here the columnar jointing is seen near the João Gomes bridge from the Jardim Botânico.
