Lichens are a unique group of plants, comprising of two micro-organisms, fungus (mycobiont), an organism capable of producing food via photosynthesis and alga (photobiont). These photobionts are predominantly members of the chlorophyta (green algae) or cynophyta (blue-green algae or cynobacteria). The peculiar nature of lichens enables them to colonize variety of substrate like rock, boulders, bark, soil, leaf and man-made buildings. -
Structural Interpretation of the Cherokee Arch, South
STRUCTURAL INTERPRETATION OF THE CHEROKEE ARCH, SOUTH CENTRAL WYOMING, USING 3-D SEISMIC DATA AND WELL LOGS by Joel Ysaccis B. ABSTRACT The purpose of this study is to use 3-D seismic data and well logs to map the structural evolution of the Cherokee Arch, a major east-west trending basement high along the Colorado-Wyoming state line. The Cherokee Arch lies along the Cheyenne lineament, a major discontinuity or suture zone in the basement. Recurrent, oblique-slip offset is interpreted to have occurred along faults that make up the arch. Gas fields along the Cherokee Arch produce from structural and structural-stratigraphic traps, mainly in Cretaceous rocks. Some of these fields, like the South Baggs – West Side Canal fields, have gas production from multiple pays. The tectonic evolution of the Cherokee Arch has not been previously studied in detail. About 315 mi2 (815 km2) of 3-D seismic data were analyzed in this study to better understand the kinematic evolution of the area. The interpretation involved mapping the Madison, Shinarump, Above Frontier, Mancos, Almond, Lance/Fox Hills and Fort Union horizons, as well as defining fault geometries. Structure maps on these horizons show the general tendency of the structure to dip towards the west. The Cherokee Arch is an asymmetrical anticline in the hanging wall, which is mainly transected by a south-dipping series of east-west striking thrust faults. The interpreted thrust faults generally terminate within the Mancos to Above Frontier interval, and their vertical offset increases in magnitude down to the basement. Post-Mancos iii intervals are dominated by near-vertical faults with apparent normal offset. -
Technology Technical Report
Technology Technical Report HYDRAULIC FRACTURING IN THE STATE OF MICHIGAN ABOUT THIS REPORT This document is one of the seven technical reports com- pleted for the Hydraulic Fracturing in Michigan Integrated Assessment conducted by the University of Michigan. During the initial phase of the project, seven faculty-led and student-staffed teams focused on the following topics: Technology, Geology/ Hydrogeology, Environment/Ecology, Human Health, Policy/ Law, Economics, and Public Perceptions. These reports were prepared to provide a solid foundation of information on the topic for decision makers and stakeholders and to help inform the Integrated Assessment, which will focus on the analysis of policy options. The reports were informed by comments from (but do not necessarily reflect the views of) the Integrated Assessment Steering Committee, expert peer reviewers, and numerous public comments. Upon completion of the peer review process, final decisions regarding the content of the reports were deter- mined by the faculty authors in consultation with the peer review editor. These reports should not be characterized or cited as final products of the Integrated Assessment. The reports cover a broad range of topics related to hydraulic fracturing in Michigan. In some cases, the authors determined that a general discussion of oil and gas development is important to provide a framing for a more specific discussion of hydraulic fracturing. The reports address common hydraulic fracturing (HF) as meaning use of hydraulic fracturing methods regardless of well depth, fluid volume, or orientation of the well (whether vertical, directional, or horizontal). HF has been used in thousands of wells throughout Michigan over the past several decades. -

In Alaska, lichenometry continues to be are beyond the latitudinal or altitudinal tree line in an important technique for dating late Holocene locations where tree-ring based dating methods moraines. Research completed during the 1970s cannot be applied. through the early 1990s developed lichen dating Lichenometry is a key method for dating curves for five regions in the Arctic and subarctic Alaskan Holocene glacier histories beyond the tree mountain ranges beyond altitudinal and latitudinal treelines. Although these dating curves are still in line. Some of the earliest well-replicated glacier use across Alaska, little progress has been made in histories in Alaska were based on lichen dates of the past decade in updating or extending them or in moraines (Denton and Karlén 1973a, b, 1977; developing new curves. Comparison of results from Calkin and Ellis 1980, 1984; Ellis and Calkin 1984) recent moraine-dating studies based on these five and the method continues to be applied today (e.g. -

Subsurface Facies Analysis of the Devonian Berea Sandstone in Southeastern Ohio
SUBSURFACE FACIES ANALYSIS OF THE DEVONIAN BEREA SANDSTONE IN SOUTHEASTERN OHIO William T. Garnes A Thesis Submitted to the Graduate College of Bowling Green State University in partial fulfillment of the requirements for the degree of MASTER OF SCIENCE December 2014 Committee: James Evans, Advisor Jeffrey Snyder Charles Onasch ii ABSTRACT James Evans, Advisor The Devonian Berea Sandstone is an internally complex, heterogeneous unit that appears prominently both in outcrop and subsurface in Ohio. While the unit is clearly deltaic in outcrops in northeastern Ohio, its depositional setting is more problematic in southeastern Ohio where it is only found in the subsurface. The goal of this project was to search for evidence of a barrier island/inlet channel depositional environment for the Berea Sandstone to assess whether the Berea Sandstone was deposited under conditions in southeastern Ohio unique from northeastern Ohio. This project involved looking at cores from 5 wells: 3426 (Athens Co.), 3425 (Meigs Co.), 3253 (Athens Co.), 3252 (Athens Co.), and 3251 (Athens Co.) In cores, the Berea Sandstone ranges from 2 to 10 m (8-32 ft) thick, with an average thickness of 6.3 m (20.7 ft). Core descriptions involved hand specimens, thin section descriptions, and core photography. In addition to these 5 wells, the gamma ray logs from 13 wells were used to interpret the architecture and lithologies of the Berea Sandstone in Athens Co. and Meigs Co. as well as surrounding Vinton, Washington, and Morgan counties. Analysis from this study shows evidence of deltaic lobe progradation, abandonment, and re-working. Evidence of interdistributary bays with shallow sub-tidal environments, as well as large sand bodies, is also present. -
