Nikita Shah Geo 201 – Homework 1 Physiographic Provinces of Pennsylvania Pennsylvania consists of 6 Physiographic Provinces, namely, (1) The Atlantic Coastal Plain Province, (2) The Appalachian Plateau Province, (3) The Ridge and Valley Province, (4) The Piedmont Province, (5) The New England Province and (6) The Central Lowlands Province. Each province has its own geology and particular type of landscape which plays a very important role in the lives of the people living in these regions. For this assignment, I am supposed to describe the geologic history of Pennsylvania’s most important provinces, i.e. the first 4 provinces. The state of Pennsylvania mostly consists of Sedimentary rocks which were deposited during the Paleozoic Era. Pennsylvania …show more content…
It also spans over south-eastern regions of Delaware and Bucks County. This province showcases a flat land with sandy soil. The coastal plain was formed as a result of erosion and deposition by rivers – it was formed by the continuous rise and fall of the ancient ocean waters. The Cenozoic sediments found here were deposited in multiple layers over the course of 150 million years. The presence of marine shells and diatoms in these sediments tell the Geologists that these layers were formed under the sea. The eroding Appalachian Mountains contributed as a major source of sediments. The rivers of the past carried down all the eroded mountain particles and settled it over the coastal …show more content…
It consists of the state’s most unique landscapes – strangely long, tapered and almost parallel ridges and valleys, all mingling over water gap formations. The province extends from the center towards New Jersey (north-eastward) and into Maryland (south-westward). The province’s ridges and valleys are made up of Sedimentary rocks from the Paleozoic Era. Metamorphosed Proterozoic volcanic rock (~575 million years old) is also found in some ridges of the South Mountain sector of the province. The sediments were originally deposited in a horizontal manner, but then these rocks were subjected to a high amount of heat and pressure during the Alleghanian orogeny, which resulted in them being folded and angular. The erosion of sediments over the years have formed a very distinct landform – valleys have been formed over areas of shale and limestone (softer rocks) and ridges have been formed in the areas of sandstone (harder rock). This Province is divided into 7 sectors: South Mountain, Great Valley, Blue Mountain, Anthracite Upland, Anthracite Valley, Susquehanna Lowland and Appalachian
The Lynne deposit lies within the early Proterozoic Penokean fold belt of the southern province of the Precambrian Shield. The fold belt is divided into two major terranes in Wisconsin (Sims 1989). The first is the northern Penokean terrane, which contains major oxide facies iron formations and granitic intrusions (DeMatties 1989). The second major terrane, separated from the Penokean terrane by the Niagara fault zone, is the Wisconsin magmatic terrane, characterized by a volcanic island arc-basin assemblage (Sims 1989). This southern terrane lacks major oxide facies iron formations, but contains abundant tonalite-granite intrusions (DeMatties 1989). The Wisconsin magmatic terrane is further subdivided into the northern Pembine-Wausau terrane and the southern Marshfield terrane, which are separated by the Eau Pleine shear zone, a north-dipping subduction zone (Sims 1989).

Determining the location of the Shawangunk Mountain formation from our position on the outcrop can demonstrate a lot about the upbringing of this formation. The Shawangunk Formation, consisting of quartz pebble conglomerate from the Middle Silurian age, extends from south of the Hudson Valley down south until Virginia. The vanishing of the formation within the area of Rosendale, NY has led to investigations of tectonic events. Due to the Taconic orogeny, we see the formation of the Shawangunk Mountains being formatted. Through the transgression of fluvial system, the Shawangunk Mountain formation rose southeast as the result of the tectonic deformation. The coarse-grained beds in the lower portion of the outcrop demonstrate a very
The northern part of the state is in the Blue Ridge Mountains. The Piedmont extends through the central part of the state. It extends from the foothills of the Blue Ridge to the Fall Line. At the Fall Line, the rivers cascade down in elevation to the coastal plain located in the
Found in the Appalachian Region, the Juniata Formation extends from central-southern Pennsylvania to Tennessee (Davies 2010). Though the thickness of the Juniata Formation is far from constant across its lateral extent, it is approximately 2000 feet thick in northern Pennsylvannia and thins towards the southwest (Crowder 1980). Named for the Juniata River running through southern Pennsylvania, this formation consists of sediments from the Taconic Orogeny in the late Ordovician period (Crowder 1980). Figure one displays the characteristic layers of alternating red sandstones and shales, which are divided into three distinct units (Darton
In 1702 Philadelphia was established by Great Britain, however modern-day Pennsylvania was granted statehood 85 years later in 1787. In between this 85 year period a lot happened including two important Pennsylvania wars. Everything basically stays the same until 1714 when something happens and Britain controls most of modern-day Pennsylvania and a group of indians called the Iroquois are driven out of modern-day Pennsylvania. Some may ask what happened and the answer I would tell them is that they just expanded and explored nothing much. 40 years later in 1754 the first war that is important to modern-day Pennsylvania, The French and Indian war. This war ends in 1764 making it a ten year war that changed all of Pennsylvania into the 12th
Right Hand: Penn is most known for founding the British colony called the Province of Pennsylvania, which is
The Ouachita Mountains were also created with the collision of Gondwana as it pushed together seafloor and are tilted or twisted folds of earth crust. Streams usually flow along the folds. Most of the mountains are made up of sandstone and shale from the bottom of the former sea. This region is usually known for unique quartz crystals,
Many historians think about how Pennsylvania had a big impact on the United States that we call home today.Pennsylvania was one of the first thirteen colonies which also means it was one of the first states to come up with laws.The reason Pennsylvania had such a big effect on the United States history is that our ancestors made fairly good decisions but they also made bad decisions.When William Penn founded Pennsylvania in 1681 on what was known as the Quaker religion. When people look at the history Pennsylvania they see the good things our ancestors chose to do when it came to setting up the thirteen colonies, but what most people overlook is the bad things they chose to do like how they slaughtered thousands of Indians at one time.So with
Pennsylvania is one of the first 13 colonies that were found in the United States. In the year of 1681 William Penn founded the colony of Pennsylvania. Pennsylvania is the 12th colonies found in the first 13. The colony of Pennsylvania was founded because William Penn was issued by King George II because of his significant debt owed to his father Admiral Penn. It was named Pennsylvania which meant Penns Woods, after Admiral Penn. Pennsylvania is one of the more average colonies in the first 13 colonies. Pennsylvania is also in the middle colonies along with the colonies of New York, New Jersey, and Delaware. Many people in the other colonies wanted to move into Pennsylvania which is where they had made their colony freedom of religion. This
Pennsylvania was one of the original 13 colonies, it became the second state administrated into the union on Dec 12 1787.Like other states Pennsylvania has a motto,Pennsylvania’s motto is “Virtue,Liberty, and Independance”.Pennsylvania’s total population is about 12,703,379 (but it’s ever changing) there is about 49,188 in Pennsylvania’s capital Harrisburg which is about 1/240 of the total poppulation. Pennsylvania’s state bird is the ruffed grouse, the state flower is the mountain laurel, and the state tree is the eastern hemlock. Pennsylvania Has many nicknames such as the keystone,oil,coal, and quaker state and state of independance. The origin of Pennsylvania’s name is from it’s founder Quaker Penn as Pennsylvania in dutch means “Penn’s Woods”.
Pennsylvania, nicknamed the Keystone State, may be the 33rd largest state area-wise, but it is the 6th largest population-wise 1. This is most-likely due to urban areas like Philadelphia and Pittsburgh, settlement of europeans after the discovery of “The New World” and, possibly, the immense amount of history and contribution to the development of the United States of America. Philadelphia is known as the “birthplace of the United States.”
Throughout the second half of the 17th century, the land now known as America experienced a large increase in colonization. One of the colonies formed during the 1680s was Pennsylvania. Pennsylvania, formed in 1683 by a Quaker named William Penn, was set up as a place of religious tolerance for the persecuted Quakers and others. In the first few laws passed in the Pennsylvania legislature called colloquially the “Great Law”, the legislators set to preserve this tolerance by declaring that”… nor shall he or she at any time be Compelled to frequent or Maintaine any Religious Worshipp place or Ministry whatever Contrary to his or her mind” . With this legislation, Pennsylvania became a place for groups such as Jews to immigrate to in order to
Compression-induced by the collision of the Iapetus rocks with North America caused a downwarp in the crust of the west Taconic mountains. Sagging crust from the downwarp was flooded by a broad shallow inland ocean and filled with sediments. This is evidenced because the Appalachian basin was formed by the downwarp in the crust of the west Taconic mountain. Sediments deposited in delta from the western side of the mountain, the Iapetus ocean, North America, Baltica, and the Gondwana plates converged. After a period of erosion, land began to subside and the water began to occupy the land.
formed are formed in a geological low-temperature metamorphic process in which involving heat and water. This process involves heat and water also in which low-silica mafic and ultramafic rocks are oxidized as well as hydrolyzed with water into serpentine. Peridotite, including, dunite, at and near the seafloor and in mountain belts is also converted to Serpentine, as well as brucite, and magnetite other minerals, and even native iron.
