Description: Abstract: The till_bedrock 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_bedrock layer shows areas of thin till, thick till, moraine deposits, bedrock outcrops, and areas of abundant outcrop and shallow bedrock for a twenty-three-quadrangle area in southeast Massachusetts. Thin till and bedrock outcrops polygons are mutually exclusive; thick till and moraine polygons overlie areas of thin till, and abundant outcrop/shallow bedrock polygons overlie areas of thin till and bedrock outcrops. This data layer should be used in conjunction with the overlying stratified_deposits and 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 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_bedrock layer shows areas of thin till, thick till, moraine deposits, bedrock outcrops, and areas of abundant outcrop and shallow bedrock for a twenty-three-quadrangle area in southeast Massachusetts. This data layer should be used in conjunction with the overlying stratified_deposits and postglacial data layers. This map of twenty-three 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.

Browse_Graphic_File_Type: pdf 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 fifteen 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maps (Mabee and others, 2004); U.S. Geological Survey personnel compiled and digitized the basic units for nine unpublished quadrangles from scanned field maps, and then joined and edge-matched the twenty four quadrangles in order to form a seamless geologic map. Security_Information: Security_Classification: Unclassified Native_Data_Set_Environment: Microsoft Windows XP Version 5.1 (Build 2600) Service Pack 3; ESRI ArcCatalog 9.3.0.1770 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. Thin till and bedrock polygons are exclusive and do not overlap other each other. Thick till and moraine polygons overlie thin till polygons. Abundant outcrop/shallow bedrock polygons overlie thin till polygons and may overlie individual bedrock outcrops. 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 twenty-three-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.

Till is mapped where it is generally less than 10 to 15 ft thick including areas of shallow bedrock. 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 are derived from coarse-grained crystalline rocks. Subsurface till overlies fresh, nonweathered bedrock; this basal till varies in known thickness from <5 to >50 ft (Williams and Willey, 1973; Williams and Tasker, 1974; Hansen and Lapham, 1992; Masterson and others, 1997). Till may overlie older Pleistocene deposits locally Enumerated_Domain_Value_Definition_Source: compiler Attribute_Domain_Values: Enumerated_Domain: Enumerated_Domain_Value: thick till Enumerated_Domain_Value_Definition: Nonsorted, nonstratified matrix of sand, some silt, and little clay containing scattered pebble, cobble, and boulders in the shallow subsurface; at greater depths consists of compact, nonsorted matrix of silt, very fine sand, and some clay containing scattered small gravel clasts. Mapped in areas where till is greater than 10 to15 ft thick, chiefly in drumlin landforms in which till thickness commonly exceeds 100 ft (maximum recorded thickness is 230 ft). Although upper till is the surface deposit, the lower till constitutes the bulk of the material in these areas. Lower till is moderately to very compact and is commonly finer grained and less stony than upper till. An oxidized zone, the lower part of a soil profile formed during a period of interglacial weathering, is generally present in the upper part of the lower till. This zone commonly shows closely spaced joints that are stained with iron and manganese oxides Enumerated_Domain_Value_Definition_Source: compiler Attribute_Domain_Values: Enumerated_Domain: Enumerated_Domain_Value: till overlying sand deposits Enumerated_Domain_Value_Definition: In the Pine Hills area, Manomet quadrangle, surface deposits of till and overlying thin colluvium, both consisting of nonsorted, nonstratified matrix of sand, some silt, and little clay containing scattered gravel clasts and few large boulders; loose to moderately compact, generally sandy, commonly stony. The surface nonsorted deposits, 6 to 30 ft thick, overlie sand, gravel, and silty sand deposits that extend >250 ft downward to basal till and bedrock (Hansen and Lapham, 1992). These subsurface stratified deposits crop out in the sides of Pine Hills and Indian Hill, where they appear to be coarse-grained glacial meltwater sediments Enumerated_Domain_Value_Definition_Source: compiler Attribute_Domain_Values: Enumerated_Domain: Enumerated_Domain_Value: end moraine deposits Enumerated_Domain_Value_Definition: Composed predominantly of boulders and ablation facies sandy upper till; lenses of stratified sand and gravel occur locally within the till. Surface boulders on end moraine deposits are generally more numerous than on adjacent till surfaces; dense concentrations of boulders are present in some places. Deposits occur as free-standing hummocky landforms, commonly in ridges that trend ENE WSW, and range in thickness from 10 to 60 ft Enumerated_Domain_Value_Definition_Source: compiler Attribute_Domain_Values: Enumerated_Domain: Enumerated_Domain_Value: thrust-moraine deposits Enumerated_Domain_Value_Definition: Surface deposits of nonsorted, nonstratified matrix of sand, some silt, and little clay containing scattered gravel clasts and 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 (Oldale, 1975). 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 sediments that compose the large meltwater deposit extending to the south and downward to basal till and bedrock. Surface deposits and stratification in underlying sediments commonly are distorted and faulted due to readvance of the ice margin (Oldale and O’Hara, 1984) postdepositional collapse related to melting of buried ice Enumerated_Domain_Value_Definition_Source: compiler Attribute_Domain_Values: Enumerated_Domain: Enumerated_Domain_Value: bedrock outcrops Enumerated_Domain_Value_Definition: extent of individual bedrock outcrops Enumerated_Domain_Value_Definition_Source: compiler Attribute_Domain_Values: Enumerated_Domain: Enumerated_Domain_Value: areas of abundant outcrop or shallow bedrock Enumerated_Domain_Value_Definition: areas of shallow bedrock or areas where small outcrops are too numerous to map individually; in areas of shallow bedrock, surficial materials are less than 5 to 10 ft thick. These units are not mapped consistently among all quadrangles; see Appendix for level of bedrock outcrop mapping in each quadrangle.
