gneiss

• All these minerals have once been imbedded in the granitic gneiss, which is the principal rock of the region In speaking of granite or gneiss in southern lands, or at least in the southern lands we now visited, I must, in the first place, point out that these rocks next the surface of the earth in the south have a much greater resemblance to strata of sand, gravel, and clay than to our granite or gneiss rocks, the type of what is lasting, hard, and unchangeable. —  The Voyage of the Vega round Asia and Europe, Volume I and Volume II
• The long ridges of quartz traversing the gneiss are marked features in the scenery of Bundкlkhand 16. —  Rambles and Recollections of an Indian Official
• Beds of granular limestone are most common in the primitive northern chain; and it is somewhat remarkable that they are found in gneiss, and not in mica-slate We find at the back of this granitic, or rather mica-slate-gneiss soil of the southern chain, on the south of the Villa de Cura, a transition stratum, composed of greenstone, amphibolic serpentine, micaceous limestone, and green and carburetted slate. —  Personal Narrative of Travels to the Equinoctial Regions of America, During the Year 1799-1804 — Volume 3
• The stratified granite of Las Trincheras, giving birth to very hot springs (from 90.5 degrees centigrade), appears from the inclination of its layers to be superposed on gneiss which is seen further southward in the islands of the lake of Valencia; but conjectures of superposition founded only on the hypothesis of an indefinite prolongation of the strata are doubtful; and possibly the granite masses which form a small particular zone in the northern range of the littoral Cordillera, between 70 degrees 3 minutes and 70 degrees 50 minutes longitude, were upheaved in piercing the gneiss. —  Personal Narrative of Travels to the Equinoctial Regions of America, During the Year 1799-1804 — Volume 3
• Between the limits here assigned to gneiss, as a predominant rock (longitude 68 1/2 to 70 1/2 degrees), gneiss passes sometimes to mica-slate, while the appearance of a transition to granite is only found on the summit of the Silla of Caracas The Silla is a mountain of gneiss like Adams Peak in the island of Ceylon, and of nearly the same height.) —  Personal Narrative of Travels to the Equinoctial Regions of America, During the Year 1799-1804 — Volume 3
