Abstract This two-day field trip focuses on the geology and geomorphology of the Carolina Sandhills in Chesterfield County, South Carolina. This area is located in the updip portion of the U.S. Atlantic Coastal Plain province, supports an ecosystem of longleaf pine ( Pinus palustris ) and wiregrass ( Aristida stricta ), and contains three major geologic map units: (1) An ~60–120-m-thick unit of weakly consolidated sand, sandstone, mud, and gravel is mapped as the Upper Cretaceous Middendorf Formation and is interpreted as a fluvial deposit. This unit is capped by an unconformity, and displays reticulate mottling, plinthite, and other paleosol features at the unconformity. The Middendorf Formation is the largest aquifer in South Carolina. (2) A 0.3–10-m-thick unit of unconsolidated sand is mapped as the Quaternary Pinehurst Formation and is interpreted as deposits of eolian sand sheets and dunes derived via remobilization of sand from the underlying Cretaceous strata. This unit displays argillic horizons and abundant evidence of bioturbation by vegetation. (3) A <3-m-thick unit of sand, pebbly sand, sandy mud, and mud is mapped as Quaternary terrace deposits adjacent to modern drainages. In addition to the geologic units listed above, a prominent geomorphologic feature in the study area is a north-trending escarpment (incised by headwater streams) that forms a markedly asymmetric drainage divide. This drainage divide, as well as the Quaternary terraces deposits, are interpreted as evidence of landscape disequilibrium (possibly geomorphic responses to Quaternary climate changes).

Abstract First, this volume explores the Haile gold mine, which is located in southern Lancaster County, South Carolina. Gold was discovered at the site in 1827, and the mine is located between the past producing Ridgeway and Brewer mines that, when all are combined, constitute a significant amount of historical gold production in the southeastern United States. The second guide focuses on the geology and geomorphology of the Carolina Sandhills in Chesterfield County, South Carolina, an area in the updip portion of the U.S. Atlantic Coastal Plain province. The third guide provides a structural analysis of the Kiokee belt and its framing elements: Savannah River transect.

Abstract A stream cut-bank at Flintstone Hill, Lauder Sandhills, Glacial Lake Hind Basin, southwestern Manitoba, exposes an extensive Holocene sedimentary sequence. Ground penetrating radar (GPR) is used to determine lateral continuity of four major stratigraphic units (wetland complex, Mid-Holocene aeolian dune, sandsheet/fluvial, Late Holocene aeolian dune) and to image primary sedimentary features within the dune strata. Depth of GPR signal penetration is only about 5 m. Signal attenuation is attributed to the presence of primarily pedogenic silts/clays and carbonate- and iron sesquioxide-rich horizons within the sandier units. Nevertheless, the stratigraphic units are shown by GPR, and confirmed by core data, to be laterally continuous within the survey area. Finer-scale dune strata are not well displayed in the aeolian units. Signal attenuation above the Mid-Holocene unit and relatively high iron sesquioxide concentrations within the unit limit imaging of well-preserved dune foreset strata. In the Late Holocene unit, depositional strata are poorly preserved and GPR primarily images soil A-horizons formed on surfaces of temporary stabilization within the dune sediment.
