| Caption: | Rock specimen of 'crumpled' chlorite schist. Roadside, 0.75 miles north-west of Loch Bad an Sgalaig, Gairloch, Rosshire, Scotland. |
| Description: | The sample is a fine-grained schist which has been folded (or crumpled) into an angular 'zig-zag' shape. The sample has a grey-green colour caused by the presence of the dominant mineral chlorite, and orange 'rusty' coloured fringes where iron oxides are present. British Geological Survey Petrology Collection sample number EMC82. A chlorite schist is a metamorphic rock with a strong elongate fabric typically defined by aligned flakes of the mineral chlorite. The presence of chlorite in a metamorphic rock generally indicates low grade regional metamorphism. The term 'crumpled' is an old name used by geologists to describe a series of folds within a rock. Part of the Lewisian (Precambrian) Loch Maree Group, part of the Southern Laxfordian Belt of relatively younger Lewisian rocks. |
