The Port Deposit Gneiss has been quarried along the east as well as the west bank of the Susquehanna River for over 100 years. Port Deposit Gneiss was used in: [2] Many houses and five churches in Port Deposit; Schools like the U.S. Naval Academy, Haverford College and The Catholic University of America; Fort McHenry, Fort Delaware and Fort Carroll
Augen gneiss, from the German: Augen, meaning "eyes", is a gneiss resulting from metamorphism of granite, which contains characteristic elliptic or lenticular shear-bound grains (porphyroclasts), normally feldspar, surrounded by finer grained material. The finer grained material deforms around the more resistant feldspar grains to produce this ...
A perched water table (or perched aquifer) is an aquifer that occurs above the regional water table. This occurs when there is an impermeable layer of rock or sediment ( aquiclude ) or relatively impermeable layer ( aquitard ) above the main water table/aquifer but below the land surface.
A water table is a projection of lower masonry on the outside of a wall, slightly above the ground, or at the top of a wainscot section of a wall (in this case also known as a sill). It is both a functional and architectural feature that consists of a projection that deflects water running down the face of a building away from lower courses or ...
Riverbeds in central and northeast Maine are lined with sandy glacial outwash made up of gneiss, limestone, phyllite, shale and granite. Much of coastal Maine has clay-loam soils from marine and lake sediments, with a water table at the surface or 12 inches below it and poor drainage throughout the year.
Glen Finglas supplies water to the city of Glasgow. [15] A dam and reservoir was built by Glasgow Corporation Water Works, as part of the Loch Katrine water supply project, between 1963 and 1965 to secure the supply of the River Turk and River Finglas. [16] [17] [15] The dam also contains a hydroelectric power station. [17]
The Western Gneiss region (Norwegian: Gneisregionen [1]) is a large geological unit in Norway chiefly made of gneiss rock that formed through metamorphism during the Caledonian orogeny. [1] It makes up a tectono-stratigraphic terrane of the Scandinavian Caledonides [ 2 ] and is also part of the Baltic shield . [ 3 ]
Laterite is a residual product created by the natural process of rocks weathering in the hot humid climatic conditions and interaction with water, oxygen and carbon dioxide. In simple terms, it is a soil formation linked to the parent rock material that has evolved because of various powers of nature in the same manner as other types of soils ...
