Gneiss ( / n aɪ s / nice ) is a common and widely distributed type of metamorphic rock . It is formed by high-temperature and high-pressure metamorphic processes acting on formations composed of igneous or sedimentary rocks . This rock is formed under pressures anywhere from 2 to 15 kbar, sometimes even more, and temperatures over 300 °C (572 °F). Gneiss nearly always shows a banded texture characterized by alternating darker and lighter colored bands and without a distinct cleavage .

However, between 1824 and 1829, with financial support from the states of Maryland, Delaware , and Pennsylvania , over 2600 workers built the 14 miles long Chesapeake and Delaware Canal , which became for a while the busiest canal in the new nation.

After petitioning for relief, the company was allowed to route the bridge closer to the falls, allowing it to be 1,000 feet (300 m) shorter. The Port Deposit Bridge , a wooden covered bridge , was built just north of Port Deposit during 1817 and 1818. Put into service in 1818, it
1290-918: A weak tendency to fracture along these layers. In Europe, the term has been more widely applied to any coarse, mica -poor, high-grade metamorphic rock. The British Geological Survey (BGS) and the International Union of Geological Sciences (IUGS) both use gneiss as a broad textural category for medium- to coarse-grained metamorphic rock that shows poorly developed schistosity, with compositional layering over 5 millimeters (0.20 in) thick and tending to split into plates over 1 centimeter (0.39 in) thick. Neither definition depends on composition or origin, though rocks poor in platy minerals are more likely to produce gneissose texture. Gneissose rocks thus are largely recrystallized but do not carry large quantities of micas, chlorite or other platy minerals. Metamorphic rock showing stronger schistosity

Migmatite is a gneiss consisting of two or more distinct rock types, one of which has the appearance of an ordinary gneiss (the mesosome ), and another of which has

The lighter bands contain relatively more felsic minerals (minerals such as feldspar or quartz , which contain more of the lighter elements, such as aluminium , sodium , and potassium ). The banding is developed at high temperature when the rock is more strongly compressed in one direction than in other directions ( nonhydrostatic stress ). The bands develop perpendicular to

Gneisses that are metamorphosed igneous rocks or their equivalent are termed granite gneisses, diorite gneisses, and so forth.

Orthogneiss designates a gneiss derived from an igneous rock , and paragneiss

For example, a gneissose metagranite or a gneissic metagranite both mean a granite that has been metamorphosed and thereby acquired gneissose texture. The minerals in gneiss are arranged into layers that appear as bands in cross section. This

Migmatites are often interpreted as rock that has been partially melted, with the leucosome representing the silica-rich melt, the melanosome the residual solid rock left after partial melting, and the mesosome the original rock that has not yet experienced partial melting. Gneisses are characteristic of areas of regional metamorphism that reaches

He sailed about 2 miles (3.2 km) up the Susquehanna River to the present location of Port Deposit, and gave the name of "Smythe Fayles" to the rapids just above the future town. In 1729, Thomas Cresap established a regular ferry service near Smith's Falls (in the upper Port Deposit area) crossing

Some banding is formed from original rock material (protolith) that

As early as the 1790s, the forests on the Susquehanna were being logged and the timbers floated downriver to points near the ferry landing. In 1812, the town was platted as Creswell's Landing; months later, Governor Levin Winder signed a bill officially naming

It had been the halfway point of the railroad line between Wilmington and Baltimore, but damage to

It was carried by the Democratic Party nominee in every Presidential election between 1868 and 1920 except that of 1896 when the Northeast was vigorously opposed to William Jennings Bryan ’s “free silver” policy. Since Dwight Eisenhower carried the county in 1952, Cecil County has become

The present-day primary method of transportation to and from Port Deposit is by road. Maryland Route 222 passes through

The Conowingo Dam , built in 1927, permanently changed the character of the town by terminating all river traffic and decimating what was left of the shad and herring fishery which was once found there. Port Deposit benefited from the dam as well; destructive accumulations of ice (referred to as ice gouges) no longer accumulated in

By June 1941, the final segment of the Philadelphia Road, the new dual highway designated as Route 40 was completed across the center of Cecil County.

Soon new motels, restaurants, and gas stations started sprouting up along what
