The Winking Man Rock formation (also known as the Winking Eye [5]) is part of the Ramshaw Rocks section of The Roaches. It looks like a face sticking out of the hillside, and as you travel past in a car towards Buxton the 'eye' appears to wink, as a pinnacle of rock passes behind the face as a consequence of parallax.
Jasper, an aggregate of microgranular quartz and/or cryptocrystalline chalcedony and other mineral phases, [1] [2] is an opaque, [3] impure variety of silica, usually red, yellow, brown or green in color; and rarely blue. The common red color is due to iron(III) inclusions. Jasper breaks with a smooth surface and is used for ornamentation or as ...
The black crystal is garnet, the pink-orange-yellow colored strands are muscovite mica, and the brown crystals are biotite mica. The grey and white crystals are quartz and (limited) feldspar. Metamorphism is the transformation of existing rock (the protolith) to rock with a different mineral composition or texture.
The following is a list of rock types recognized by geologists.There is no agreed number of specific types of rock. Any unique combination of chemical composition, mineralogy, grain size, texture, or other distinguishing characteristics can describe a rock type.
Other colors of chalcedony may also occur in Indian bloodstone, such as white, yellow, or blue. This semiprecious stone should not be confused with other ornamental stones that contain red jasper. Setonite, also called African bloodstone, is composed of red jasper, grey chalcedony, and pyrite .
A hoodoo (also called a tent rock, fairy chimney, or earth pyramid) is a tall, thin spire of rock formed by erosion. Hoodoos typically consist of relatively soft rock topped by harder, less easily eroded stone that protects each column from the elements. They generally form within sedimentary rock and volcanic rock formations.
These include human and semi-human figures as well as animals (birds, snakes, deer, oxen) and human-made objects (sleds, scepters, rattles and head dresses). In contrast, the ‘Long Rocher’ school, with 80 panels, presents panels of mainly geometric engravings that resemble the Mesolithic petroglyphs described above. [ 8 ]
