Szabo Charles W. Copeland, Jr. Thornton L. Neathery 1989 raster digital data Alabama Geological Survey of Alabama Special Map 221 https://ngmdb.usgs.gov/Prodesc/proddesc_55860.htm A digital version of the 1:500,000 scale geologic map of Alabama (Osborne and others, 1989) was required for a new national compilation of state geologic maps and U.S. Geological Survey regional maps, but the map had not previously been digitized. The USGS National Cooperative Geologic Mapping Program’s (NCGMP) National Geologic Synthesis Project worked with the Geological Survey of Alabama (GSA) to digitize the map in the NCGMP’s Geologic Map Schema (GeMS) format. The GSA provided an image of the map, which the USGS team georegistered and used as a base to digitize the vector lines and populate the nonspatial tables. Once the map content was encoded in a GeMS database, the GSA reviewed the map and provided corrections to both the vector lines and text content in the nonspatial tables, primarily the descriptions of map units. The content of this database is as faithful as possible to the original 1989 printed map. When displayed using the FGDC Digital Cartographic Standard for Geologic Map Symbolization (USGS Techniques and Methods 11-A2, 2006) it closely approximates the lines symbols and colors of the original map. This data set is a digital reproduction of the 1989 Geologic Map of Alabama at 1:500,000 scale. AL_500K_SM221 is a composite geodataset that conforms to GeMS (Geologic Map Schema)--a standard format for the digital publication of geologic maps", available at http://ngmdb.usgs.gov/Info/standards/GeMS/.

This data set is GeMs Level 3 valid using the current version of the GeMS toolbox as of June 26, 2024 This data set is a digital reproduction of the Geologic Map of Alabama that includes line and polygon features, as well as the text description of each map unit. No changes were made to the data on account of more recent information. Estimated accuracy of horizontal location is given on a per-feature basis by attribute LocationConfidenceMeters. Values are expected to be correct within a factor of 2. A LocationConfidenceMeters value of -9 or -9999 indicates that no value has been assigned.

This report GeoMaterialCategorization of map unit based on lithologic and genetic character, term selected from NGMDB standard term list defined in Appendix A of GeMS documentation, available at http://ngmdb.usgs.gov/Info/standards/GeMS..GeMS Chert Sedimentary rock, composed chiefly of microcrystalline or cryptocrystalline quartz. GeMS Residual material Unconsolidated material, developed in place by weathering of underlying rock or sediment. Usually forms relatively thin surface layer that conceals unweathered or partly altered source material. Material from which soils are formed. GeMS Sandstone and mudstone Sandstone and mudstone (including shale and siltstone), in approximately equal (or unspecified) proportions. GeMS Fine-grained, mafic-composition intrusive igneous rock Rock that solidified from molten or partly molten material (magma) at shallow depth beneath Earths surface, thereby cooling quickly. Generally fine grained but may contain large mineral crystals (phenocrysts). Mostly found as tabular dikes or sills. Composed mostly of dark-colored minerals. Includes basaltic rock. GeMS Schist and gneiss, of sedimentary-rock origin Foliated rock derived from preexisting sedimentary rocks by essentially solid-state mineralogical, chemical, or structural changes in response to marked changes in temperature, pressure, deformation, and (or) chemical environment, generally at depth in Earths crust. Includes schist (characterized by such strong foliation or alignment of minerals that it readily splits into flakes or slabs) and gneiss (characterized by alternating, irregular bands of different mineral composition). Mostly formed from fine-grained material such as mudstone. GeMS Metasedimentary rock Rock derived from preexisting sedimentary rocks and altered by essentially solid-state mineralogical, chemical, or structural changes, in response to marked changes in temperature, pressure, deformation, and (or) chemical environment, generally at depth in Earths crust. GeMS Sandstone Sedimentary rock, composed predominantly of particles or clasts derived by erosion and weathering of preexisting rock; consists mostly of sand-sized particles, with or without fine-grained matrix of silt or clay. GeMS Meta-mafic rock Rock derived from preexisting mafic rocks by essentially solid-state, mineralogical, chemical, or structural changes, in response to marked changes in temperature, pressure, deformation, and (or) chemical environment, generally at depth in Earths crust. Composed mostly of iron- and magnesium-bearing, dark-colored and (or) green minerals. Includes greenstone, amphibolite, and metagabbro.

Regarding the subjective term "adequately characterize", we refer to context and objectives of this classification as described in the GeMS documentation. GeMS documentation Medium The term and definition generally characterize the overall lithology of the map unit, but there are one or more significant minor lithologies that are not adequately described by the selected term. GeMS documentation Low The overall lithology of this map unit is not adequately classifiable using this list of terms and definitions, but the term selected is the best available. Or this map unit is insufficiently known to confidently assign a GeoMaterial term. GeMS documentation DescriptionOfMapUnits_ID Primary key. GeMS Arbitrary string.

Origin of preexisting rock is mixed (for example, igneous and sedimentary) or is not known. Includes amphibolite, granulite, schist, and gneiss. GeMS Meta-ultramafic rock Rock derived from preexisting ultramafic rocks by essentially solid-state, mineralogical, chemical, or structural changes, in response to marked changes in temperature, pressure, deformation, and (or) chemical environment, generally at depth in Earths crust. Composed mostly of magnesium-bearing minerals (for example, serpentine, talc, magnesite). GeMS Carbonate sediment Sediment formed by biotic or abiotic precipitation from aqueous solution of carbonates of calcium, magnesium, or iron (for example, limestone, dolomite). GeMS Rock Various rock types, not differentiated. GeMS Contact-metamorphic rock Altered rock that originated by local processes of thermal metamorphism, genetically related to intrusion and extrusion of magmas and taking place at or near contact with body of igneous rock. Metamorphic changes are effected by heat and fluids emanating from magma and by some deformation because of emplacement of igneous mass. GeMS Extrusive igneous material Molten material that was erupted onto Earths surface, fusing into rock or remaining as unconsolidated particles. Includes pyroclastic flows, air-fall tephra, lava flows, and volcanic mass flows. GeMS Peat and muck Unconsolidated material, principally composed of plant remains, with lesser amounts of fine-grained clastic sediment. Deposited in water-saturated environment such as swamp, marsh, or bog. With lithification, such material becomes coal. GeMS IndentedName Name with addition of leading spaces to help show rank within a hierarchical list. GeMS Unrepresentable domain Definition Plain-language definition. GeMS Unrepresentable domain MapUnitPolys Polygons that record distribution of map units (including water, snowfields, glaciers, and unmapped area) on the particular map horizon.

IdentityConfidenceConfidence that feature is correctly identified.GeMS certain Identity of a feature can be determined using relevant observations and scientific judgment; therefore, one can be reasonably confident in the credibility of this interpretation. Federal Geographic Data Committee [prepared for the Federal Geographic Data Committee by the U.S. Geological Survey], 2006, FGDC Digital Cartographic Standard for Geologic Map Symbolization: Reston, Va., Federal Geographic Data Committee Document Number FGDC-STD-013-2006, 290 p., 2 plates. Label Plain-text equivalent of the desired annotation for a feature: for example "14 Ma", or "^c" which (when used with the FGDC GeoAge font) results in the geologic map-unit label TRc (with TR run together to make the Triassic symbol). GeMS Unrepresentable domain Symbol Reference to a point marker, line symbol, or area-fill symbol that is used on the map graphic to denote the feature: perhaps a star for a K-Ar age locality, or a heavy black line for a fault. GeMS Unrepresentable domain PlotAtScale At what scale (or larger) should this observation or analysis be plotted? At smaller scales, it should not be plotted. Useful to prevent crowding of display at small scales and to display progressively more data at larger and larger scales. Value is scale denominator. GeMS Positive real number.
