Based on lithological, structural and geophysical characteristics, the Proterozoic Grenville Orogen of southern Ontario and New York has been divided into domains that are separated from each other by ductile shear zones. In order to constrain the timing of metamorphism, U-Pb ages were determined on metamorphic and igneous sphenes from marbles, calc-silicate gneisses, amphibolites, granitoids, ...

Abstract Ordovician and Silurian siliciclastic, volcanic, plutonic rocks in the southern Appalachian eastern Blue Ridge western Inner Piedmont, formerly interpreted as components of an obducted Taconic arc terrane, are recognized parts paired arc/back-arc system that formed on seaward edge Laurentian plate. New crystallization ages from metamorphosed plutonic-volcanic intruding intercalated wit...

Despite much progress, many questions remain regarding the potential dynamic coupling between atmospheric and lithospheric processes in the long-term evolution of mountain belts. As a complement to recent efforts to discover the interrelationships among climate, topography, erosion, and rock deformation under conditions of mass-flux steady state, we explore orogen response to changes in climate...

The theme of this issue of Preventing Chronic Disease (PCD) — Appalachia — will stir a collage of images in readers' minds. A dominant image is likely to be derived from the great Appalachian mountain chain of eastern North America. A saddle gap in the top ridge of that mountain chain may yield a glimpse of a meandering river whose banks are covered with pastures and small towns where friends a...

Appalachia has higher morbidity and mortality compared to the nation, and suffers greater socioeconomic disadvantages. This article investigates the relationship of coal mining to elevated mortality rates in Appalachia. Total mortality rates for the years 1999–2004 were investigated in a national county-level analysis that included coal mining as the primary independent variable. Counties in Ap...

UNLABELLED Lesbian, gay, and bisexual (LGB) people are affected by multiple health disparities and risk factors, including tobacco use. Few studies to date have examined tobacco use specifically in rural LGB populations, and none has investigated the intersections of identity, rural LGB culture, and tobacco. The purpose of this study was to explore the perspective of Appalachian LGB people rega...

Obesity and inactivity are prevalent among central Appalachian adolescents. Appalachian residents have been labeled " fatalistic, " a time perspective unsupportive of health-promoting behaviors such as regular participation in physical activity. The theory of planned behavior has been used extensively to explain the physical activity behaviors of adolescents. Constructs within the theory of pla...
