- Abstract:
-
The postglacial data layer is part of a comprehensive study to produce a statewide digital map of the surficial geology at a 1:24,000-scale. This compilation of surficial geologic materials defines the areas of exposed bedrock, and the boundaries between glacial till, glacial stratified deposits, and overlying postglacial deposits. The postglacial layer shows areas of swamp deposits, floodplain alluvium, and artificial fill for a 16-quadrangle area in northeast Massachusetts. Swamp and alluvium polygons are mutually exclusive; artificial fill polygons may overlie areas of swamp or alluvium. This data layer should be used in conjunction with the underlying till_bedrock, stratified_deposits, and early_postglacial data layers.
- Purpose:
-
The purpose of this study is to provide fundamental geologic data for the evaluation of natural resources, hazards, and land information within the Commonwealth of Massachusetts. The postglacial data layer is part of a comprehensive effort to produce a statewide digital map of the surficial geology at a 1:24,000-scale. This compilation of surficial geologic materials defines the areas of exposed bedrock, and the boundaries between glacial till, glacial stratified deposits, and overlying postglacial deposits. The postglacial layer shows areas of swamp deposits, salt-marsh deposit, floodplain alluvium, artificial fill and beach and dune deposits for a 16-quadrangle area in northeast Massachusetts. This data layer should be used in conjunction with the underlying till_bedrock, stratified_deposits, and early_postglacial data layers.
This map of 16 quadrangles revises previous digital surficial geologic maps (Stone and Beinikis, 1992, MASSGIS surficial map coverage) that were compiled on base maps at regional scales of 1:250,000.

- Data_Set_Credit:
-
Multiple agencies and individuals contributed to this data layer: MASSGIS scanned and georeferenced paper copies of the published surficial geologic maps for six quadrangles; the Office of the Massachusetts State Geologist vectorized the georeferenced images and compiled geologic units in order to digitally retain the original information on the published maps (Mabee and others, 2004); U.S. Geological Survey personnel compiled and digitized the basic units for ten unpublished quadrangles from scanned field maps, and then joined and edge-matched the 16 quads in order to form a seamless geologic map.

- Attribute_Accuracy_Report: Attributes have been visually checked by the compilers.
- Logical_Consistency_Report:
-
Polygon features conform to the following topological rules. There are no duplicate polygons. Polygons do not self overlap. Swamp deposits and floodplain alluvium polygons are exclusive and do not overlap other each other. Artificial fill polygons may overlie swamp or alluvium polygons. No automated procedures or tests were performed to guarantee desired topology other than visual inspection.
- Completeness_Report:
-
The completeness of the data reflects the feature content of the basic units chosen for this interim product for all data sources. Additional information can be found on the data sources, which may be utilized in future compilations. The layer is complete in the sense that it accurately reflects the postglacial units for this 16 quadrangle area, noting that edits (including additional units) may occur to this data set when it is edgematched to surrounding quadrangles during future compilations.

-
- Horizontal_Positional_Accuracy:
-
- Horizontal_Positional_Accuracy_Report:
-
The horizontal positional accuracy of this data complies with the United States National Map Accuracy Standards for 1:24,000 scale maps. According to this standard, not more than 10 percent of the locations tested are to be in error by more than 1/50 inch (40 feet) measured on the publication scale of a USGS 7.5 minute topographic quadrangle map.

The Office of the Massachusetts State Geologist vectorized the georeferenced images in order to digitally retain the original line work of the published maps (Mabee and others, 2004). Digital geologic map units were compiled and grouped into seven basic units and attributed: artificial fill, swamp deposits, floodplain alluvial deposits, glacial stratified deposits, glacial till, thick till (drumlins), and bedrock areas (outcrops and areas of shallow bedrock).

Unpublished field sheets were scanned and georeferenced. Geologic units were vectorized or created (on screen digiziting). Basic unit coverages for each layer in each quad were edited, edgematched and appended into a single layer for each geologic unit (covering all unpublished quads).

Basic unit coverages for unpublished and published areas were edgematched, edited as needed and appended. Units were converted to shapefile format and combined into the 4 final layers and reattributed for consistency.

- Enumerated_Domain_Value: floodplain alluvium
- Enumerated_Domain_Value_Definition:
-
Sand, gravel, silt, and some organic material, stratified and well sorted to poorly sorted, beneath the floodplains of modern streams. The texture of alluvium commonly varies over short distances both laterally and vertically, and generally is similar to the texture of adjacent glacial deposits. Along smaller streams, alluvium is commonly less than 5 ft thick. The most extensive deposit of alluvium on the map is along the Merrimack River where the texture is predominantly sand, fine gravel, and silt, and total thickness is as much as 25 ft. Alluvium typically overlies thicker glacial stratified deposits.

- Enumerated_Domain_Value: artificial fill
- Enumerated_Domain_Value_Definition:
-
Earth materials and manmade materials that have been artificially emplaced, primarily in highway and railroad embankments, and in dams; may also include landfills, urban development areas, and filled coastal wetlands

-
- Enumerated_Domain_Value: swamp deposits
- Enumerated_Domain_Value_Definition:
-
organic muck and peat that contain minor amounts of sand, silt, and clay, stratified and poorly sorted, in kettle depressions or poorly drained areas. Most swamp deposits are less than about 10 ft thick. Swamp deposits overlie glacial deposits or bedrock. They locally overlie glacial till even where they occur within thin glacial meltwater deposits.

- Enumerated_Domain:
-
- Enumerated_Domain_Value: salt-marsh deposits
- Enumerated_Domain_Value_Definition:
-
peat and organic muck interbedded with sand and silt, deposited in environments of low wave energy along the coast and in river estuaries. Marsh deposits are dominantly peat and muck, generally a few feet to 25 ft thick. In the major estuaries, marsh deposits locally overlie estuarine deposits (not mapped) which are sand and silt with minor organic material as much as 30-80 ft thick. The marsh and estuarine deposits generally are underlain by adjacent glacial material, either till, coarse stratified deposits, or glaciomarine fine deposits.

- Enumerated_Domain:
-
- Enumerated_Domain_Value: beach and dune deposits
- Enumerated_Domain_Value_Definition:
-
sand and fine gravel deposited along the shoreline by waves and currents, and by wind action. The texture of beach deposits varies over short distances and is generally controlled by the texture of nearby glacial materials exposed to wave action. Sand beach deposits are composed of moderately sorted very coarse to fine sand, commonly laminated. Coarser layers may contain some fine gravel particles; finer layers may contain some very fine sand and silt. Gravel beach deposits are composed of granule-to-cobble-sized clasts in moderately sorted thin beds. Minor amounts of sand within gravel beds, and thin beds of sand as alternating layers. Beach deposits are rarely more than a few feet thick. Sand dune deposits are composed of moderately to well sorted, fine to medium sand, variably massive, laminated, and cross bedded. Dune deposits are as much as 35 ft thick. Unit includes artificial sand deposits in locally replenished beaches.
