Heights Quarry works exposures of the Great Limestone for aggregate, and is developed on the former site of the underground Heights Mine. The old underground workings have long been inaccessible for the most part, but recent quarry operations have exposed portions of the Heights South and West Cross veins, once again enabling the occasional recovery of specimens.
More DetailsIts definition is derived from the Mohr-Coulomb failure criterion and is used to describe the friction shear resistance of soils together with the normal effective stress. In the stress plane of Shear stress-effective normal stress, the soil friction angle is the angle of inclination with respect to the horizontal axis of the Mohr-Coulomb shear ...

More DetailsDiabase: A hand specimen of diabase approximately ten centimeters across. The bottom salt-and-pepper colored portion is a polished surface displaying the plagioclase (white) and pyroxene (black) minerals that make up this specimen of an intrusive igneous rock. The top part nicely displays a light gray weathering rind that is typical of diabase.
More DetailsGreywacke. Greywacke is variation of sandstone that saperate from other to hardness, dark color, and poorly sorted angular grains of quartz and feldspar.. It is a textural immature sedimentary rock found in the Paleozoic layers. Larger grains can be from sand to pebble length, and matrix materials are in the order of 15% by volume of rocks.

More DetailsPegmatites have been located in Upper Teesdale and at Barrasford quarry in Northumberland – one of the many whinstone roadstone quarries. In some areas, pectolite has been deposited in joints due to late stage hydrothermal mineralisation and, as we see on Holy Island, carbonitisation has altered some areas of dolerite to 'White Whin'.
