In other words, we found evidence to suggest that visuospatial ability mattered for bedrock mapping for theīedrock geologic map of the Grafton quadrangle, Worcester County, Massachusetts More importantly, we found a Visuospatial Ability Ã- Geological Knowledge interaction, such that visuospatial ability positively predicted mapping performance at low, but not high, levels of geological knowledge. We found that both geological knowledge and spatial visualization ability correlated positively with accuracy in the field mapping task. Data were examined for correlations between performance on the mapping task and other measures. In addition to participants' geologic maps and field notes, the cognitive suite included tests and questionnaires designed to measure: (1) prior geologic experience, via a self-report survey (2) geologic content knowledge, via a modified version of the Geoscience Concept Inventory (3) visuospatial ability, working memory capacity, and perceptual speed, via paper-and-pencil and computerized tests (4) use of space and time during mapping via GPS tracking and (5) problem-solving in the field via think-aloud audio logs during mapping and post- mapping semi-structured interviews.

To better understand cognition during geologic mapping, we conducted a 2-year research study in which 67 volunteers representing a range from undergraduate sophomore to 20+ years professional experience completed a suite of cognitive measures plus a 1-day bedrock mapping task in the Rocky Mountains, Montana, USA. Most post-secondary geology students in the United States receive training in geologic mapping, however, not much is known about the cognitive processes that underlie successful bedrock mapping, or about how these processes change with education and experience. Successful mapping requires domain-specific content knowledge, visuospatial ability, navigation through the field area, creating a mental model of the geology that is consistent with field data, and metacognition. LaDue, N.īedrock geologic mapping is a complex and cognitively demanding task. Novice to Expert Cognition During Geologic Bedrock Mapping Sheet 3 on the back features a list of the 195 sources of geologic map data keyed to an index map of 7.5-minute quadrangles in Vermont, as well as a table identifying ages of rocks dated by uranium-lead zircon geochronology. Sheet 3 on the front consists of descriptions of 486 map units, a correlation of map units, and references cited. These sheets also include 10 cross sections and a geologic structure map. Sheets 1 and 2 show the southern and northern halves of Vermont, respectively, and can be trimmed and joined so that the entire State can be displayed as a single entity. The printed map consists of three oversize sheets (52 x 76 inches). The current map was created to integrate more detailed (1:12,000- to 1:24,000-scale) modern and older (1:62,500-scale) mapping with the theory of plate tectonics to provide a framework for geologic, tectonic, economic, hydrogeologic, and environmental characterization of the bedrock of Vermont. The 1961 map was compiled from 1:62,500-scale or smaller maps. Mapped rock units are primarily based on lithology, or rock type, to facilitate derivative studies in multiple disciplines. At a scale of 1:100,000, the map shows an uncommon level of detail for State geologic maps.

Doll and others in 1961 and a full 150 years since the publication of the first geologic map of Vermont by Edward Hitchcock and others in 1861. The new map comes 50 years after the most recent map of the State by Charles G. The State's complex geology spans 1.4 billion years of Earth's history. Geological Survey (USGS) and the State of Vermont. The Bedrock Geologic Map of Vermont is the result of a cooperative agreement between the U.S.
