Manhattan Prong
The Manhattan Prong of the New England Uplands is a smaller belt of ancient rock in southern New York (including Manhattan, the Bronx, and segments of Brooklyn and Staten Island), parts of Westchester County, and upland portions of southwestern Connecticut. The Manhattan Prong and the Reading Prong are separated by the Newark Basin in the south, but the two features merge at the northern terminus of the Newark Basin in the vicinity of Peekskill, New York. A band of mountains that rise nearly one thousand feet along the northwestern margin of the Newark Basin in New York and New Jersey are called the Ramapo Mountains. Another belt of ancient metamorphic and igneous rock crops out along the southern margin of the Newark Basin south and west of Trenton, New Jersey. In this region the rocks are referred to as part of the Trenton Prong. This region includes Manhattan schist and Tuckahoe marble Tuckahoe marble (also known as Inwood and Westchester marble) is a type of marble found in ...

New England Uplands
The topography of the New England Uplands section is that of a maturely-dissected plateau with narrow valleys, and the entire area is greatly modified by glaciation. It is the most widespread of the geomorphic sections in the New England Province, extending from Canada through New England down to the Seaboard section and extending southwestward through New York and New Jersey as two narrow upland projections, the Reading Prong and the Manhattan Prong. Numerous hills and mountains rise above the general level of the upland; except in the presence of mountains, the horizon of the regional landscape is fairly level. Glaciation has resulted in the erosion and rounding off of the bedrock topography and numerous rock basin lakes. Glacial drift is thin, patchy, and stony, and ice-contact features such as kames, kame terraces, and eskers are abundant. The surface of the New England Uplands slopes southeast from maximum inland altitudes around , excluding the other mountainous sections of the ...

Peekskill, New York
Peekskill is a city in northwestern Westchester County, New York, United States, from New York City. Established as a village in 1816, it was incorporated as a city in 1940. It lies on a bay along the east side of the Hudson River, across from Jones Point in Rockland County. The population was 25,431 at the 2020 US census, an increase over 23,583 during the 2010 census. It is the third largest municipality in northern Westchester County, after the towns of Cortlandt and Yorktown. The area was an early American industrial center, primarily for iron plow and stove products. The Binney & Smith Company, now named Crayola LLC and makers of Crayola products, is linked to the Peekskill Chemical Company founded by Joseph Binney at Annsville in 1864, and succeeded by a partnership by his son Edwin and nephew Harold Smith in 1885. The well-publicized Peekskill Riots of 1949 involved attacks and a lynching-in-effigy occasioned by Paul Robeson's benefit concerts for the Civil Ri ...

Appalachian Mountains
The Appalachian Mountains, often called the Appalachians, (french: Appalaches), are a system of mountains in eastern to northeastern North America. The Appalachians first formed roughly 480 million years ago during the Ordovician Period. They once reached elevations similar to those of the Alps and the Rocky Mountains before experiencing natural erosion. The Appalachian chain is a barrier to east–west travel, as it forms a series of alternating ridgelines and valleys oriented in opposition to most highways and railroads running east–west. Definitions vary on the precise boundaries of the Appalachians. The United States Geological Survey (USGS) defines the ''Appalachian Highlands'' physiographic division as consisting of 13 provinces: the Atlantic Coast Uplands, Eastern Newfoundland Atlantic, Maritime Acadian Highlands, Maritime Plain, Notre Dame and Mégantic Mountains, Western Newfoundland Mountains, Piedmont, Blue Ridge, Valley and Ridge, St. Lawrence Valley, Appal ...

Geology Of New York (state)
The geology of the State of New York is made up of ancient Precambrian crystalline basement rock, forming the Adirondack Mountains and the bedrock of much of the state. These rocks experienced numerous deformations during mountain building events and much of the region was flooded by shallow seas depositing thick sequences of sedimentary rock during the Paleozoic. Fewer rocks have deposited since the Mesozoic as several kilometers of rock have eroded into the continental shelf and Atlantic coastal plain, although volcanic and sedimentary rocks in the Newark Basin are a prominent fossil-bearing feature near New York City from the Mesozoic rifting of the supercontinent Pangea. Stratigraphy, Tectonics & Geologic History The igneous and metamorphic crystalline basement rock of New York formed in the Precambrian and are coterminous with the Canadian Shield. The Adirondack Mountains, Thousand Islands, Hudson Highlands, and Fordham gneiss, along with outcrops in the Berkshires just over ...

Geology Of Connecticut
As part of New England, Connecticut has undergone much geologic change shaped by plate tectonics, volcanism, and glacial activity. Appalachian Mountains During the early Triassic period, the super-continent Pangea was formed as the Iapetus Ocean closed up and the proto-North American continent collided with Avalonia, part of modern-day Africa. This caused great uplift and the creation of the Appalachian Mountains, which, at the time, were bigger than modern-day Himalayas. Erosion of the Appalachian Mountains now exposes metamorphic rocks once very deep in the Earth's mantle (geology), mantle and uplifted during this time period. Eastern Border Fault About 200 million years after this collision and the formation of Pangea, during the middle of the Mesozoic Era, the Atlantic Ocean floor started spreading and great extensional forces were experienced, resulting in Geologic fault, faulting. Connecticut's Eastern border fault was created, a fault which begins in New Haven, Connecticut, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tuckahoe Marble
Tuckahoe marble (also known as Inwood and Westchester marble) is a type of marble found in southern New York state and western Connecticut. Part of the Inwood Formation of the Manhattan Prong, it dates from the Late Cambrian to the Early Ordovician ages (~484 ma ago). It was first quarried on a large scale commercially in the village of Tuckahoe, New York. Deposits are also found in the Inwood area of Manhattan, New York City, in Eastchester, New York, and extending southward to parts of the Bronx, such as Kingsbridge, Mott Haven, Melrose and Tremont and Marble Hill. Other locations in Westchester County include Ossining, Hastings, and Thornwood. Description and geology Tuckahoe marble is a high quality marble first quarried on a large commercial scale in 1822 in the village of Tuckahoe in Westchester County. The marble is from the larger Inwood Formation or deposit, which stretches northeasterly from mid-Manhattan through southern Westchester and into western Conn ...

Trenton Prong
The Trenton Prong is a physiographic subprovince of the Piedmont Uplands section of the Piedmont province of the Appalachian Mountains. The prong consists of crystalline metamorphic rock. Location The Trenton Prong stretches from near Norristown, Pennsylvania, through northern Philadelphia and southern Bucks County, reaching its northern terminus in West Windsor Township, New Jersey. The prong underlies much of the City of Trenton, and forms a series of rapids known as the Falls of the Delaware River. Geology The Trenton Prong is part of the Precambrian basement which is discontinuously exposed in the north-central Appalachians. The rocks that make up the prong are mostly Ediacaran and Cambrian aged rocks, that includes the Wissahickon Formation. Other rocks present include metabasalt, gabbro, gneiss, migmatite and granofels Granofels is a term referring to medium- to coarse-grained metamorphic rocks which have a '' granoblastic'' texture (having poorly formed, equi-granular ...

Ramapo Mountains
The Ramapo Mountains are a forested chain of the Appalachian Mountains in northeastern New Jersey and southeastern New York, in the United States. They range in height from in New Jersey, and in New York. Several parks and forest preserves encompass parts of the Ramapos (see Points of interest, below), and many hiking trails are in the Ramapos, including sections of the Appalachian Trail, which is maintained and updated in the Ramapo Mountains by the New York–New Jersey Trail Conference. The mountains are named after the Ramapo Fault, which trends northeast to southwest, and separates the eastern Piedmont geologic province from the Highland province. The Ramapos are composed of granite, gneiss, and marble, as old as 1.3 billion years.

Newark Basin
The Newark Basin is a sediment-filled rift basin located mainly in northern New Jersey but also stretching into south-eastern Pennsylvania and southern New York. It is part of the system of Eastern North America Rift Basins. Geology Approximately 220 million years ago, during the late Triassic Period, the supercontinent Pangaea began to break apart. The focus of the rifting began somewhere between where present-day eastern North America and north-western Africa were joined. As in all rifting environments, grabens formed. Many of these grabens were created, but for some of them, extension stopped before full rifting occurred. Where only partial rifting occurred, basins formed, analogous to the present-day Basin and Range Province in western United States. By definition, a basin is any area that collects sediments. These "aborted rifts" (rifts that are tectonically inactive and no longer collecting sediments) extend from North Carolina to Newfoundland. Along certain basins, rifti ...
