Note on association of Pentacrinus with lignite

J. F. Jackson
Published: 01 July 1966
Geological Magazine (1966) 103 (4): 365–366.
...J. F. Jackson Abstract Generally considered to have been attached to driftwood floating in the Liassic sea, Pentacrinus remains have now been found in the Stonebarrow cliff area (England) which demonstrate that lignite occurs above the crinoid-bearing beds. GeoRef, Copyright 2004, American...

ABSTRACT Calcite twinning analysis across the central, unbuttressed portion of the Sevier thin-skin thrust belt, using Cambrian–Cretaceous limestones ( n = 121) and synorogenic calcite veins ( n = 31), records a complex strain history for the Sevier belt, Idaho and Wyoming, USA. Plots of fabric types (layer-parallel shortening, layer-normal shortening, etc.), shortening and extension axes for the Paris thrust (west, oldest, n = 11), Meade thrust ( n = 46), Crawford thrust ( n = 15), Absaroka thrust ( n = 55), Darby thrust ( n = 13), Lander Peak klippe ( n = 5), eastern Prospect thrust ( n = 6), and distal Cretaceous foreland ( n = 3) reveal a W-E layer-parallel shortening strain only in the Prospect thrust and distal foreland. Calcite twinning strains in all western, internal thrust sheets are complex mixes of layer-parallel (LPS), layer-normal (LNS), and non-plane strains in limestones and synorogenic calcite veins. This complex strain fabric is best interpreted as the result of oblique convergence to the west and repeated eastward overthrusting by the Paris thrust.
