Question: What was a mountain building period that ended 440 million years ago, that durring this time a unit of interbedded greywackes and shales that outcrops in eastern New York State were deposited in a deep marine setting in a foreland basin during this time? 

full_context: Document 1: Piedmont Mountains: The Piedmont Mountains are outlying mountains, sometimes called “low mountains”, that typically occur in the western Piedmont near the Blue Ridge. Most of the features within the Piedmont physiographic region of North America lie either on the eastern border where the plateau plunges onto the Coastal Plain at the Fall Line, in the broad valleys of the river systems, or on the western border where Piedmont Mountains likely occur. Occasionally, due to diverse rock formations, folds and outcroppings, these mountains can rise at various locations across the Piedmont like the Uwharrie Mountain Range in North Carolina or the Pine Mountain Range in Georgia. Most of these mountains, or hills, are what is left of ancient eroded mountains. Some, like Stone Mountain in Georgia, are solitary rock domes called Monadnocks which become further exposed with erosion. The Piedmont is part of the greater Appalachian Mountain Range and is also referred to as the Appalachian Plateau. The French definition of piedmont in itself translates as foothill; however, a Piedmont Mountain may be that of greater significance or prominent elevation.
Document 2: Eramosa: The term was first used for a stratigraphic unit by Williams (1915) who named the Eramosa Member (of the Lockport Formation) for the bituminous dolomites exposed below the Guelph Formation along the Eramosa River, northeast of Guelph, Ontario. No detailed description of the type section has ever been published, and the status of the unit has been subject to many different interpretations. Until recently, the Eramosa in Ontario was regarded as the highest Member of the Lockport Formation, with gradational contacts with the Goat Island Member (below) and the Guelph Formation (above). In 1995, the US Geological Survey proposed a revised stratigraphy based on studies in the Niagara region. It extended the Lockport to Group status and included, from base to top, the Gasport, Goat Island, Eramosa, and Guelph as Formations within the Lockport Group. In a “reference section” in the Niagara River Gorge, the Eramosa was divided into six “units” recognized throughout the Niagara region, but a shaley lower unit previously named for the Hamilton area (the Vinemount Member) was transferred to the Goat Island Formation. Brunton (2009) has proposed a revision for Ontario which restores the Vinemount Member to the Eramosa and recognizes two other members.
Document 3: Laramide orogeny: The Laramide orogeny was a period of mountain building in western North America, which started in the Late Cretaceous, 70 to 80 million years ago, and ended 35 to 55 million years ago. The exact duration and ages of beginning and end of the orogeny are in dispute. The Laramide orogeny occurred in a series of pulses, with quiescent phases intervening. The major feature that was created by this orogeny was deep-seated, thick-skinned deformation, with evidence of this orogeny found from Canada to northern Mexico, with the easternmost extent of the mountain-building represented by the Black Hills of South Dakota. The phenomenon is named for the Laramie Mountains of eastern Wyoming. The Laramide orogeny is sometimes confused with the Sevier orogeny, which partially overlapped in time and space.
Document 4: North Georgia mountains: The Georgia Mountains Region or North Georgia mountains or Northeast Georgia is an area that starts in the northeast corner of Georgia, United States, and spreads in a westerly direction. The mountains in this region are in the Blue Ridge mountain chain that ends in Georgia. At over 1 billion years of age, the Blue Ridge mountains are among the oldest mountains in the United States and sometimes mistaken to be the oldest mountains in the world (they are only about one third of the age of South Africa's 3.6 billion year old Barberton greenstone belt.). The mountains in this region are also a part of the vast system of North American mountains known as the Appalachian Mountains that spans most of the United States longitudally along the eastern areas of the nation and terminates in Alabama.
Document 5: Flysch: Flysch is a sequence of sedimentary rocks that is deposited in a deep marine facies in the foreland basin of a developing orogen. Flysch is typically deposited during an early stage of the orogenesis. When the orogen evolves, the foreland basin becomes shallower and molasse is deposited on top of the flysch. It is therefore called a syn-orogenic sediment (deposited contemporaneously with mountain building).
Document 6: Clinton Group: The Clinton Group (also referred to as the Clinton Formation or the Clinton Shale) is a mapped unit of sedimentary rock found throughout eastern North America. The interval was first defined by the geologist Lardner Vanuxem, who derived the name from the village of Clinton in Oneida County, New York where several well exposed outcrops of these strata can be found. The Clinton Group and its lateral equivalents extend throughout much of the Appalachian Foreland Basin, a major structural and depositional province extending from New York to Alabama. The term has been employed in Kentucky, Maryland, Michigan, New York, Ohio, Pennsylvania, Tennessee, Virginia, and West Virginia, though in many of these areas the same interval is referred to as the Rose Hill, Rockwood, or Red Mountain Formations. Historically the term "Clinton" has also been assigned to several lower Silurian stratigraphic units in Ohio and Kentucky which are now known to be significantly older than the Clinton Group as it was originally defined. Many parts of this succession are richly fossiliferous, making the Clinton Group an important record of marine life during the early Silurian. Several economically valuable rock-types are found within this interval, though it is perhaps best known as a significant source of iron ore
Document 7: Becraft Formation: The Becraft Formation is a geologic formation of marine sedimentary rock found in New York State. The Becraft is a part of the lower Devonian Helderberg Group and conformably overlies the New Scotland Formation and is overlain by the Alsen Formation throughout the lower Hudson Valley of New York State. The formation is Gedinnian in age. Outcrops of the formation are found from the New York-New Jersey border to the Helderbergs of Albany County, New York and as far west as Schoharie County, New York. The thickness of the formation varies from around 3 meters in Canajoharie to 8 meters thick in Albany and swells to 27 meters near Kingston. The Becraft Formation is named for Becraft Mountain in western Columbia County, New York where it prominently crops out.
Document 8: Bowland Shale Formation: The Bowland Shale Formation is a Carboniferous geological formation of Asbian (Visean) to Yeadonian (Bashkirian) age. It is known from outcrop and subsurface borehole data in the north of England, the Isle of Man, parts of North Wales and the Midlands. It is an organic-rich shale which, according to the British Geological Survey, is the source rock where "oil and gas matured before migration to conventional fields in the East Midlands and the Irish Sea", for example, the Formby oil field.
Document 9: Taconic orogeny: The Taconic orogeny was a mountain building period that ended 440 million years ago and affected most of modern-day New England. A great mountain chain formed from eastern Canada down through what is now the Piedmont off the East coast of the United States. As the mountain chain eroded in the Silurian and Devonian periods, sediments from the mountain chain spread throughout the present-day Appalachians and midcontinental North America.
Document 10: Naukluft Mountains: The Naukluft Mountains are a nappe complex: a stack of rock units which have been transported toward the southeast on a basal thrust fault. The first geological maps and cross sections of the mountain range were made in the 1930s by Henno Martin and Hermann Korn. The rocks are interbedded sediments, dominated by dolostones, quartzites and shales, deposited in a shallow marine environment in the hinterland of the Damara Orogeny between 700-500 million years ago. The sediments are equivalent in age to the Otavi Mountainlands sediments where evidence for snowball earth climates was described by Paul F. Hoffman. The same lithologies are present in the Naukluft Mountains, but the sediments are folded and faulted so the original stratigraphy is deformed and inverted.
Document 11: Austin Glen Member: The Austin Glen Member of the Normanskill Formation is an upper Middle Ordovician unit of interbedded greywackes and shales that outcrops in eastern New York State. It was deposited in a deep marine setting in a foreland basin during the Taconic orogeny. Its sediment source was mainly the erosion of preexisting sedimentary rocks. Graptolite fossils place it in the stratigraphic zones of "Nematograptus gracilis" and "Climacograptus bicornis", but its age could be Llandeilo or Trentonian (earliest to latest Darriwilian,  465 ).
Document 12: Appalachian Mountains: The Appalachian Mountains ( , French: "les Appalaches" ), often called the Appalachians, are a system of mountains in eastern North America. The Appalachians first formed roughly 480 million years ago during the Ordovician Period. It once reached elevations similar to those of the Alps and the Rocky Mountains before naturally occurring 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 roads running east or west.
Document 13: Cobequid fault: The Cobequid Fault is a fault that is the extension of the Chedabucto Fault. This fault runs from Truro to Cape Chignecto south of the Cobequid Hills. Both the Cobequid fault and the Chedabucto Fault form the Minas Fault zone splitting Nova Scotia into the Avalon Zone and the Meguma Zone. Movement on the Cobequid Fault started before 400 million years ago and end around 40 million years ago. Between that time around 350 million years violent volcanic eruptions at Spicers Cove north Cape Chignecto Provincial Park and 50 million years after grey sandstone rich in fossil plants were deposited. At Five Islands Provincial Park there are red rocks formed by the large accumulation of mud, sand and gravel around 210 million years ago.
Document 14: Northern Appalachians Seismic Zone: The Northern Appalachians Seismic Zone is an active seismic zone in the Appalachian Mountains of eastern North America, extending from New Brunswick southwards into New England and Boston. Both the seismic zone and the resultant Appalachian Mountains were created by the collision of two tectonic plates about 440–480 million years ago during the middle Ordovician Period.
Document 15: Slide Mountain Ocean: The Slide Mountain Ocean was an ancient ocean that existed between the Intermontane Islands and North America beginning around 245 million years ago in the Triassic period. It is named after the Slide Mountain Terrane, which is composed of rocks from the ancient oceanic floor. There was a subduction zone on the Slide Mountain Ocean's floor called the Intermontane Trench where the Intermontane Plate was being subducted under North America. The floor of the Slide Mountain Ocean was pushed up onto the ancient margin of North America.
