New England is a region in the North Eastern United States consisting of the states Rhode Island, Connecticut, Massachusetts, New Hampshire, Vermont, and Maine.Most of New England consists geologically of volcanic island arcs that accreted onto the eastern edge of the Laurentian Craton in prehistoric times.
A geological map of the state, showing the north–south trend of the bedrock strata. The geology of Massachusetts includes numerous units of volcanic, intrusive igneous, metamorphic and sedimentary rocks formed within the last 1.2 billion years.
The New England water resource region is one of 21 major geographic areas, or regions, in the first level of classification used by the United States Geological Survey to divide and sub-divide the United States into successively smaller hydrologic units. These geographic areas contain either the drainage area of a major river, or the combined ...
The map is similar to modern geological maps of England (albeit today's maps use flat-colouring) reflecting its general accuracy in the eastern and south eastern regions of the country. However Smith's geology of western part of England and Wales was much less detailed and accurate.
Connecticut's Eastern border fault was formed, a fault which begins in New Haven and stretches 130 miles up to Keene, New Hampshire. As a result, the land west of this fault was downset, resulting in a rift valley and causing the land to tilt an average of 15 to 25 degrees. The fault is currently inactive.
In geology, the New England Seaboard (Lowland) is a physiographic section of the New England province. It includes a thin section of coastal Connecticut , most of Rhode Island , and roughly the coastal counties of Massachusetts , New Hampshire , and Maine .
There are two subsections of the New England Uplands in addition to the Reading Prong. A prong of the same rock belt extends from the Hudson Highlands south to New York City along the Hudson River. This region is often referred to as the Manhattan Prong. Staten Island Serpentinite is a southward extension of the New England Uplands. [2]
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 ...
