Till and moraine deposits of the Pocasset-Provincetown-Cuttyhunk-Nantucket 24-quadrangle area of Cape Cod and Islands, southeast Massachusetts

Data format: Shapefile

File or table name: till

Coordinate system: State Plane Coordinate System 1983

Theme keywords: surficial geology, stratified materials, stratified deposits, till, moraine, glacial deposits, beach, alluvium, swamp deposits, artificial fill, dune, cranberry bog

Abstract: The till data layer is part of a comprehensive study to produce a statewide digital map of the surficial geology at 1:24,000 scale. This compilation of surficial geologic materials defines the boundaries between glacial till, glacial stratified deposits, and overlying postglacial deposits. The till layer shows areas of thin till, thrust-moraine deposits, and moraine deposits for a twenty-four-quadrangle area in southeast Massachusetts. Thrust-moraine deposit polygons overlie areas of thin till; moraine polygons may overlie thrust_moraine polygons or thin till polygons. This data layer should be used in conjunction with the overlying stratified_deposits data layer and the postglacial deposits data layer.

FGDC and ESRI Metadata:

Metadata elements shown with blue text are defined in the Federal Geographic Data Committee's (FGDC) Content Standard for Digital Geospatial Metadata (CSDGM). Elements shown with green text are defined in the ESRI Profile of the CSDGM. Elements shown with a green asterisk (*) will be automatically updated by ArcCatalog. ArcCatalog adds hints indicating which FGDC elements are mandatory; these are shown with gray text.

Description:
Abstract:
The till data layer is part of a comprehensive study to produce a statewide digital map of the surficial geology at 1:24,000 scale. This compilation of surficial geologic materials defines the boundaries between glacial till, glacial stratified deposits, and overlying postglacial deposits. The till layer shows areas of thin till, thrust-moraine deposits, and moraine deposits for a twenty-four-quadrangle area in southeast Massachusetts. Thrust-moraine deposit polygons overlie areas of thin till; moraine polygons may overlie thrust_moraine polygons or thin till polygons. This data layer should be used in conjunction with the overlying stratified_deposits data layer and the postglacial deposits data layer.

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 till deposits data layer is part of a comprehensive effort to produce a statewide digital map of the surficial geology at 1:24,000 scale. This compilation of surficial geologic materials defines the boundaries between glacial till, glacial stratified deposits, and overlying postglacial deposits. The till layer shows areas of thin till, thrust-moraine, and moraine deposits for a twenty-four-quadrangle area in southeast Massachusetts. This data layer should be used in conjunction with the overlying stratified_deposits data layer and the postglacial deposits data layer.
This map of twenty-four quadrangles revises previous digital surficial geologic maps (Stone and others, 1993; MassGIS, 1999) 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 fourteen 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 twenty four quadrangles in order to form a seamless geologic map.

Data Quality Information:


Attribute accuracy:
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.  Moraine deposits may overlie thin till and thrust moraine polygons. Thrust moraine polygons may overlie thin till 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 till and moraine units for this twenty-four quadrangle area, noting that edits (including additional units) may occur to this data set when it is edge-matched to surrounding quadrangles during future compilations.

Positional accuracy:
Horizontal positional accuracy:
Horizontal positional accuracy report:
The horizontal positional accuracy of these 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.

Attribute domain values:
Enumerated domain:
Enumerated domain value: thin till
Enumerated domain value definition:
Nonsorted, nonstratified matrix of sand, some silt, and little clay containing scattered gravel clasts and few large boulders; predominantly upper till of the last glaciation; loose to moderately compact, generally sandy, commonly stony. Two facies are present in some places: a looser, coarser-grained ablation facies, melted out from supraglacial position; and an underlying more compact, finer-grained lodgement facies deposited subglacially. Both ablation and lodgement facies of upper till are sandy and stony, and derived from coarse-grained crystalline rocks. Unit includes till of probable Illinoian age beneath eastern Nantucket (Oldale and others, 1982).  Beneath Cape Cod, subsurface till overlies fresh, nonweathered bedrock; this basal till varies in known thickness from <5 to >50 ft (Cotton and Koteff, 1962; Masterson and others, 1997; Folger and others, 1978; Hall and others, 1980). Till may overlie Cretaceous, Tertiary, or older Pleistocene deposits beneath the adjacent islands.

Attribute domain values:
Enumerated domain:
Enumerated domain value: moraine deposits
Enumerated domain value definition:
Surface deposits of nonsorted, nonstratified matrix of sand, some silt, and little clay containing scattered gravel clasts and few large boulders; predominantly till of the last glaciation; loose to moderately compact, generally sandy, commonly stony. Two facies of till are present in some places: a looser, coarser-grained ablation facies, melted out from supraglacial position; and an underlying more compact, finer-grained lodgement facies deposited subglacially. Both ablation and lodgement facies of till are stony, containing boulders, and are derived from coarse-grained crystalline rocks. The surface nonsorted deposits, 6 to 30 ft thick, overlie sand, gravel, and silty sand meltwater deposits that extend downward to basal till and bedrock. Surface deposits and stratification in underlying sediments commonly are distorted and faulted due to postdepositional collapse related to melting of buried ice.

Enumerated domain value: thrust-moraine deposits
Enumerated domain value definition:

Both ablation and lodgement facies of till are stony, containing boulders, and are derived from coarse-grained crystalline rocks. In western Martha's Vineyard, thrust-moraine deposits include thin surface till and subsurface ice-thrusted beds of Tertiary fossiliferous sand, gravel, and silty clay deposits, and Pleistocene sand and silty clay beds. In eastern Nantucket, moraine deposits include thin surface till and ice-thrusted beds of sandy glacial meltwater deposits, interglacial marine sand, and older till at the base.
