Ecoregions of New England Forested Land Cover, Nutrient-Poor Frigid and Cryic Soils (Mostly Spodosols), and Numerous High-Gradient Streams and Glacial Lakes

It is a relatively sparsely populated region compared to adjacent regions, and is characterized by hills and mountains, a mostly Ecoregions of New England forested land cover, nutrient-poor frigid and cryic soils (mostly Spodosols), and numerous high-gradient streams and glacial lakes. Forest vegetation is somewhat transitional between the boreal regions to the north in Canada and the broadleaf deciduous forests to the south. Typical forest types include northern hardwoods (maple-beech-birch), northern hardwoods/spruce, and northeastern spruce-fir forests. Recreation, tourism, and forestry are primary land uses. Farm-to-forest conversion began in the 19th century and continues today.

Geologic Characterization of the Morrow B Reservoir in Farnsworth Unit, TX Using 3D VSP Seismic, Seismic Attributes, and Well Logs
Geologic characterization of the Morrow B reservoir in Farnsworth Unit, TX using 3D VSP seismic, seismic attributes, and well logs. by Paige Czoski Submitted in Partial Fulfillment of the Requirements for the Degree of Master of Science in Geophysics New Mexico Institute of Mining and Technology Socorro, New Mexico December, 2014 ABSTRACT Farnsworth Field is located in Ochiltree, Texas and has been selected for a Carbon Capture Utilization and Storage (CCUS) project that is being supported by the Department of Energy, the Southwest Regional Partnership on Carbon Sequestration, and Chaparral Energy Co. LLC. One million tonnes of 100% CO2 produced from the Arkalon Ethanol Plant in Liberal KS and the Agrium Fertilizer Plant in Borger TX will be injected into the Morrow B formation and monitored using seismic methods (Grigg and McPherson, 2012). Previous geologic char- acterization hypothesizes that the Morrow B Formation was an incised valley depositional environment. This study focuses on the 3D Vertical Seismic Profile (VSP) survey that overlaps two injection wells covering an area of approximately 1 by 2 miles. The purpose of this study is to geologically characterize the 3D VSP using seismic attributes and well logs. The Morrow B was auto picked in the 3D VSP data using gamma ray logs to locate the formation in depth. Low amplitude lens features that resemble channels were manually picked within the Morrow B. Seismic attributes aided in the geologic characterization by providing litho- logic and stratigraphic interpretations. The attributes discussed in this study are curvature, instantaneous frequency, signal envelope, sweetness, relative acoustic impedance, chaos, root mean square amplitude, and variance. -

Palaeontologia Electronica DISCRIMINATION OF
Palaeontologia Electronica http://palaeo-electronica.org DISCRIMINATION OF FENESTRATE BRYOZOAN GENERA IN MORPHOSPACE Steven J. Hageman and Frank K. McKinney ABSTRACT Concepts for generic diagnoses and discrimination of biserial fenestrate Bryozoa (Fenestellidae) have varied historically, but have largely been based on specialized colony forms (e.g., Archimedes), the shape and budding arrangement of chambers and other internal skeletal features such as hemisepta, and occasionally on the pres- ence or absence of discrete characters, such as placement of nodes on the frontal sur- face (e.g., Minilya). The question remains as to whether biserial fenestrate genera represent real biological clades, or whether they are convenient groupings of morpho- types based on untested characters. This study evaluates the distribution of 1075 operational taxonomic units (OTUs) from 15 fenestrate genera with measurements for nine morphometric characters – external features are not emphasized in most generic diagnoses. Here, each OTU represents a composite or idealized individual from a col- ony. Results show that OTUs plotted in principal component space do largely form coherent clusters based on a priori generic assignments. Thus the groupings based on characters other than the ones used to originally define them, add support to the notion of biological significance for recognized genera. The exceptions actually highlight and help resolve known issues. Therefore, we recognize Alternifenestella as a junior syn- onym of the genus Spinofenestella, and propose reassignment of Laxifenestella serrat- ula in Snyder (1991) to Fenestella serratula, and Fenestella sp. 1 in Ernst and Schroeder (2007) as Rectifenestella. We do not advocate that biserial fenestrate generic concepts should be based on the nine external characters used in this study, but rather that they can be used independently to evaluate the coherence of genera based on other discrete characters. -
Brachiopods from the Mobarak Formation, North Iran
GeoArabia, 2011, v. 16, no. 3, p. 129-192 Gulf PetroLink, Bahrain Tournaisian (Mississippian) brachiopods from the Mobarak Formation, North Iran Maryamnaz Bahrammanesh, Lucia Angiolini, Anselmo Alessandro Antonelli, Babak Aghababalou and Maurizio Gaetani ABSTRACT Following detailed stratigraphic work on the Mississippian marlstone and bioclastic limestone of the Mobarak Formation of the Alborz Mountains in North Iran, forty-eight of the most important brachiopod taxa are here systematically described and illustrated. The ranges of the taxa are given along the Abrendan and Simeh Kuh stratigraphic sections, located north of Damgham. The examined brachiopod species date the base of the Mobarak Formation to the Tournaisian, in absence of age-diagnostic foraminifers. Change in brachiopod settling preferences indicates a shift from high energy, shallow-water settings with high nutrient supply in the lower part of the formation to quieter, soft, but not soppy substrates, with lower nutrient supply in the middle part of the Mobarak Formation. Brachiopod occurrence is instead scanty at its top. The palaeobiogeographic affinity of the Tournaisian brachiopods from North Iran indicates a closer relationship to North America, Western Europe and the Russian Platform than to cold-water Australian faunas, confirming the affinity of the other biota of the Alborz Mountains. This can be explained by the occurrence of warm surface-current gyres widely distributing brachiopod larvae across the Palaeotethys Ocean, where North Iran as other peri- Gondwanan blocks acted as staging-posts. INTRODUCTION The Mississippian Mobarak Formation of the Alborz Mountains (North Iran) has been recently revised by Brenckle et al. (2009) who focused mainly on its calcareous microfossil biota and refined its biostratigraphy, chronostratigraphy and paleogeography. -

This is one of many related papers that were included in the 1961 NMGS Fall Field Conference Guidebook. Annual NMGS Fall Field Conference Guidebooks Every fall since 1950, the New Mexico Geological Society (NMGS) has held an annual Fall Field Conference that explores some region of New Mexico (or surrounding states). Always well attended, these conferences provide a guidebook to participants. Besides detailed road logs, the guidebooks contain many well written, edited, and peer-reviewed geoscience papers. These books have set the national standard for geologic guidebooks and are an essential geologic reference for anyone working in or around New Mexico. Free Downloads NMGS has decided to make peer-reviewed papers from our Fall Field Conference guidebooks available for free download. Non-members will have access to guidebook papers two years after publication. Members have access to all papers. This is in keeping with our mission of promoting interest, research, and cooperation regarding geology in New Mexico. However, guidebook sales represent a significant proportion of our operating budget. Therefore, only research papers are available for download. Road logs, mini-papers, maps, stratigraphic charts, and other selected content are available only in the printed guidebooks.

It is a known producer of hydrocarbons in the subsurface of Oklahoma and Kansas. There is a high level of complexity associated with the Bentonville and other Mississippian formations resulting in inadequate correlations and poor well performance in some cases. This stems from the use of oversimplified depositional models and limited understanding of how the Mississippian System responded and evolved over time as a result of sea level variation at various frequencies.
