Abstract:
Abstract We use data recorded by four arrays of portable instruments to investigate the propagation of short period (0.2≤T ≤2.0 sec) surface waves within the Ozark Uplift and Illinois Basin. At the regional scale, we construct group velocity dispersion curves for five suites of propagation paths, and invert them for shear velocity structure. The best model in each case consists of a single layer above a halfspace, and we can correlate the model units with geologic formations. The upper layer in the two Ozark Uplift models represents Ordovician and Cambrian carbonate strata, the halfspace corre

Abstract:
A new classification for the Carboniferous System/Period is formally adopted by the Kansas Geological Survey (KGS), and Zeller (1968) is modified accordingly. The Carboniferous is the system/period between the Devonian and Permian, and the Mississippian and Pennsylvanian are subsystems/subperiods of the Carboniferous. The Mississippian is subdivided into Lower, Middle, and Upper Mississippian Series and the Pennsylvanian is subdivided into Lower, Middle, and Upper Pennsylvanian Series. Regional stage names remain unchanged.

Abstract:
Current seismic design practice often relies on the use of the uniform hazard response spectrum (UHRS), which implicitly includes motions from multiple earthquake sources and envelops possible spectra, yet does not represent a single event. Seismic hazard analyses at the site of a major Mississippi River crossing near St. Louis, Missouri, showed bimodal seismic hazard dominated by small, nearby earthquakes at short periods and large, distant earthquakes in the New Madrid seismic zone at long periods. UHRS motions resulted in large seismic demands and predictions of pervasive liquefaction that

Abstract:
Recent work has shown that there is a predictable inverse relationship between laboratory-measured sonic velocity response and porosity in carbonates, which can be reasonably approximated using the empirical Wyllie time-average equation (WTA). The relationship was initially identified in late Cretaceous to Cenozoic age samples collected from the Great Bahama Bank and the Maiella Platform, an exhumed Cretaceous carbonate platform in Italy. We have compared older carbonate samples from different basins and different geologic ages to determine the applicability of this relationship and subsequent

Abstract In the Ostrava part of the Upper Silesian Basin there are many geotouristic sites connected with the underground mining of Carboniferous bituminous coal. Text is focused on those related to the geology of the Basin and environmental issues connected to coal mining. Of great intrest are outcrops of Mississippian sediments of the paralic Ostrava Formation, as well as two most important museums with permanent geological exhibitions. Some interesting geological features conncted to younger periods of Quarternary glaciation are also mentioned. Two types of publicly accessible sites related

Abstract. In the Devonian–Carboniferous, a rapid succession of clustered extensional and contractional tectonic events is thought to have affected sedimentary rocks in central Spitsbergen, Svalbard. These events include Caledonian post-orogenic extensional collapse associated with the formation of thick Early–Middle Devonian basins, Late Devonian–Mississippian Ellesmerian contraction, and Early–Middle Pennsylvanian rifting, which resulted in the deposition of thick sedimentary units in Carboniferous basins like the Billefjorden Trough. The clustering of these varied tectonic settings sometimes

The State of Louisiana is leading an integrated wetland restoration and flood risk reduction program in the Mississippi River Delta. East of New Orleans, Biloxi Marsh, a ~1700 km2 peninsula jutting 60 km north toward the State of Mississippi is one of few Delta wetland tracts well positioned to dissipate hurricane surge and waves threatening the city’s newly rebuilt hurricane flood defenses.

Abstract:
AbstractIt has been said that large rivers are the bloodlines of continents, and the Mississippi River system is the most prominent bloodline in North America. The Mississippi drainage stretches from the Rocky Mountains in the western USA to the Appalachian Cordillera in the east, and sediment from this vast area is then routed to the alluvial–deltaic plain of south Louisiana and the basin-floor fan in the deep Gulf of Mexico (GoM). Origins of the Mississippi system can be traced to the Late Cretaceous–Early Paleocene reorganization of North American drainage. However, integration of a contine

Abstract:
The Thomas Farm fossil site, Gilchrist County, Florida, is the most fossiliferous Hemingfordian terrestrial site east of the Mississippi River. Taphonomy indicates that the formation of the fossil deposit occurred over a period of at most thousands of years, a geologic instant. Thomas Farm contains one of the earliest and numerically largest populations of the small equid Archaeohippus. Although the sample of mandibles is small (MNI=30), I was able to recognize nine age grades for Archaeohippus blackbergi.

Abstract:
The Iberian Pyrite Belt (IPB) represents one of the largest districts of volcanogenic massive sulfide (VMS) deposits in the world, and is a critical source of base metals (Cu, Pb, and Zn) for Europe. Confirmed resources exceed 1700 Mt of massive sulfides with grades of around 1.2% Cu, 1% Pb, and 3% Zn as well as more than 300 Mt of stockwork-type copper mineralization. Significant resources of Sn, precious metals (Au and Ag), and critical metals (Co, Bi, Sb, In, and Se) have also been evaluated. The genesis of these deposits is related to a complex geological evolution during the late Devonian

Abstract:
Hydrothermal fluids, hot groundwaters that circulate within the Earth’s crust, play central roles in many geological processes, including the genesis of a broad variety of ore deposits, the chemical alteration of rocks and sediments, and the origin of hot springs and geothermal fields. Many studies have been devoted to modeling how hydrothermal fluids react chemically as they encounter wall rocks, cool, boil, and mix with other fluids. Such modeling proliferated in part because hydrothermal fluids are highly reactive and because the reaction products are commonly well preserved, readily studie
