By Tanner, Geoff Abstract: None of the major roles assigned to the Highland Boundary Fault, such as a transcurrent fault with an orogen- parallel, sinistral displacement of several hundred kilometres, or terrane boundary, are confirmed. The Highland Boundary Fault can be traced NE-SW across Scotland for >240 km and defines the northern margin of the Midland Valley. Except for small outliers of Late Palaeozoic rocks on the NW side, it separates the Highland Border Ophiolite and Dalradian...

By Schofield, D I Evans, J A; Millar, I L; Wilby, P R; Aspden, J A A new U-Pb date of 615.2 +- 13 (2sigma) Ma for the Twt Hill Granite, North Wales, contrasts with an Rb-Sr isochron age of 491 +- 12 (2sigma) Ma from the same body. The latter age is thought to result from isotope resetting during regional low-grade metamorphism or fault reactivation. The Rb-Sr age also coincides with the onset of latest Cambrian to Early Tremadoc regression and is taken to reflect tectonic uplift prior to...

Mucrospirifer
2014-01-12 00:00:00

Mucrospirifer is a genus of extinct brachiopod of the order Spiriferida. This genus is sometimes known as the “butterfly shells.” Fossils of this genus occur mostly in the Middle Devonian strata. When alive, this genus mainly lived in muddy marine sediments, and were attached to the sea floor via its pedicle (foot). The bi-convex shell was about an inch long, and sometimes grew to 1.6 inches. The shell has a fold, groove and rod-like structure. It is elongated along the hinge line,...

Atrypa (lampshell) is an extinct genus of brachiopod from the Late Ordovician stage (444 million years ago) to the Carboniferous stage (318 mya). It occurs abundantly as fossils in marine rocks. Fossils have been found on all continents except Antarctica. This animal has distinctive concentric growth lines and is unusual in that in some Devonian beds there are numerous remains of the pedicle (foot) valve, but very few of the brachial (upper) valve -- scientists speculate that strong ocean...
