- THE NEW YORK CITY SERIES - NYSGA Online
The New York City series comprise s three distinct formations or rock units of strongly metamorphosed character Starting with the oldest, they are the Fordham gneis s, Inwood marble (sometine s called a lime stone) and Manhattan schist
- Metamorphic series - Wikipedia
A metamorphic facies series is a sequence of metamorphic facies which plot in a temperature-pressure diagram along a line, and this line represents a certain geothermal gradient
- PROVENANCE AND TECTONIC HISTORY OF METAMORPHIC ROCKS OF CENTRAL PARK . . .
The rocks underlying much of New York City, frequently referred to as the “Manhattan Prong”, predominately consist of a series of metasedimentary units, which were originally deposited into the Iapetus Ocean and subsequently deformed and metamorphosed during the Taconic, Acadian, and Alleghenian Orogenies (Merguerian and Merguerian , 2014
- AMNH | Geology of NYC| Manhattan Prong | Geology of Central Park
New York City is primarily composed of sediments that were metamorphosed during the Taconic and Acadian orogenies roughly 500 - 400 million years ago Garnets can be found in the rocks of the Hartland Formation and Manhattan Schist (view a NYC rock sample )
- 10. 5: Metamorphic Facies and Index Minerals
The yellow, green, and blue dashed lines in Figure 10 34 tell you what metamorphic facies you will encounter for rocks from a given depth in that particular environment
- Types of Metamorphism - Tulane University
Such a progression is termed a facies series, and in general terms this would be called a high pressure facies series, as shown in the diagram below Such a facies series would be expected in areas near subduction zones where cool lithosphere is pushed to higher pressure
- NEW YORK CITY BEDROCK - GeologyVirtualTrips
DESCRIPTION: There are three major rock formations that make-up the bedrock of New York City In stratigraphic order, these are the Fordham Gneiss, Inwood Marble, and Manhattan Schist These three metamorphic rock types are referred to as the New York City Group
- STRATIGRAPHY, STRUCTURAL GEOLOGY, AND DUCTILE- AND BRITTLE FAULTS OF . . .
New York City is situated at the southern terminus of the Manhattan Prong, a northeast-trending deeply eroded sequence of metamorphosed Proterozoic to Lower Paleozoic rocks that widen northeastward to form the crystalline terranes of western New England
