1992
Geology Of The Upper Allegheny River Region In Warren County, Northwestern Pennsylvania
Leaders:
W.D. Sevon, L.R. Auchmoody, T.M. Berg, S.W. Berkheiser Jr, H.L. Delano, C.H. Dodge, J.A. Harper,E.M. Hopkins, J.D. Inners, W.E. Kochanov, M.E. Moore, A. A. Panah, D.A. Stewart, J.M. Tarantino, D.L. Woodrow
Warren County was the site of such pioneering geological investigations as John Carll’s oil and gas studies in the 1880’s and Charles Butts’ folio-mapping in the early 1900’s. The Warren Field Conference emphasized 1) some new and exciting regional findings obtained from a concurrent PaGS mapping effort, and 2) the results of a variety of related topical studies (ranging from Upper Devonian stratigraphy to periglacial phenomena and forest ecology).
1991
Geology In The South Mountain Area, Pennsylvania
Leaders:
W.D. Sevon, N. Potter, R. Ackermann, J.H. Barnes, A.E. Becher, S.W. Berkheiser Jr, D.C. Chichester, G.M. Clark, G. Docktor, H.W.A. Hanson, M.M. Key Jr, S. Lev, L. Pezzoli, R.J. Schott, S.J. Simms, S.I. Root, R.C. Smith II, T. Troy, R.L. Van Scyoc, J.H. Way, C.C. Wilderman, and E.L. Yochehlson
Precambrian metavolcanics and Cambrian clastics comprise the rocks deformed during the development of the South Mountain Anticlinorium. Their lithologies and metamorphosed sedimentary structures provide considerable insight into the ancient geologic history of South Mountain. Topographic forms, various surficial deposits, and weathering products provide enticing glimpses of more recent climate/process development of the present landscape.
1990
Carbonates, Schists, And Geomorphology In The Vicinity Of The Lower Reaches Of The Susquehanna River
Leaders:
C.K. Scharnberger, N.J. Durika, R.T. Faill, G.R. Ganis, D. Hopkins, W.M. Jordan, D.B. MacLachlan, W.D. Sevon, J.F. Taylor, G.H. Thompson Jr., D.W. Valentino, D. Wyckoff
The 55th Field Conference focused on three topics of new field work and new thinking about the geology of western Lancaster and eastern York Counties. These are: 1) the age, facies, and tectonic relationships of the carbonate rocks which are extensively quarried in the two counties, 2) the structural history of the schists (and related rocks) which lie south of the Martic Line, and 3) the origin and age of the dramatic landscape in and around the gorge of the lower Susquehanna River.
1989
Geology In The Laurel Highlands Of Southwestern Pennsylvania
Leaders:
J.A. Harper, F. Baldassare, W.A. Bragonier, D.K. Brezinski, K.R. Cercone, A. Iranpanah, U. Kaktins, F.J. Knight, C.D. Laughrey, R. Naylor, J.F. Taylor, B. Walker, S.D. Weedman, R.W. Wood
The 54th Field Conference examined the stratigraphy and sedimentary geology of the latest Devonian and earliest Mississippian rocks exposed in western Pennsylvania, the geology of Mississippian carbonates, Pennsylvanian freshwater limestones and flint clays, geochemistry of calcium carbonate polymorphs in Pennsylvanian marine fossils, coal mining and related environmental problems. And an overview of the infamous Johnstown floods.
1988
Bedrock And Glacial Geology Of The North Branch Susquehanna Lowland And The Eastern Middle Anthracite Field
Leaders:
D.D. Braun, N.M. Gillmeister, J.D. Inners, W.E. Edmunds, M.A. Landis, L.J. Lentz, D.A. Springer
The 53rd Field Conference emphasized new findings on the glacial history of the North Branch Susquehanna River lowland and adjacent Anthracite regions, the structural geology of the Light Street fault between Bloomsburg and Berwick, and the stratigraphy of the Pottsville Formation in the Eastern Middle field. Also included was a tour of the Eckley Miner’s Village, the only preserved “mine patch” in the Anthracite fields and former abode of the “Molly Maguires.”
1987
Pleistocene And Holocene Geology On A Dynamic Coast
Leaders:
D.J. Thomas, M.R. Buyce, C.H. Carter, H.L. Delano, K. Taylor
The Field Conference examined some of the ice-marginal landforms, and some landforms developed by changing lake level. Attendees examined various diamicts, and sand and gravel facies which comprise these landforms. Problems of determining sedimentary environments and related sedimentological history were emphasized.
1986
Selected Geology Of Bedford And Huntingdon Counties
Leaders:
W.D. Sevon, T.M. Berg, S.W. Berkheiser Jr, E. Cotter, C.H. Dodge, W.E. Edmunds, R.T. Faill, A.D. Glover, J.D. Inners, T.L. Kaktins, L.J. Lentz, J. Cullen-Lollis, A.M. Thompson, E.G. Williams
In the spring of 1836, three geologists of the First Geological Survey of Pennsylvania made a trip across Pennsylvania examining rocks along a traverse which included the valleys of the Little Juniata and Juniata Rivers in Huntingdon County. Later that summer field work began with the measurement of the Paleozoic section from the Broad Top along the course of Yellow Creek. This field work established the correct sequence of Paleozoic stratigraphy for the Appalachians. The 1986 Field Conference revisited some of the outcrops first examined in 1836 and considered them in light of modern geologic thought. The trip examined much of the Paleozoic section and included structures in Bedford and Huntingdon Counties, as well as the first ever Field Conference stop in the coal-bearing rocks of the Broad Top.
1985
Central Pennsylvania Geology Revisited: Coral Reef; The Catskill Clastics; Quaternary And Tertiary Geology; Deformed Zones; Exploration And Exploitation Of Coal
Leaders:
D. P. Gold, R. J. Cuffey, A. Davis, T. Gardner, R. R. Parizek, H. Pohn, A. W. Rose, R. Slingerland, B. Voight, E. G. Williams, and W. White
The Golden Jubilee Conference returned to topics examined at the first Field Conference emphasizing the advances made in our understanding since that time. In addition, and to emphasize the prominent role geology plays in society today, two applied topics-Geology in the Exploration and Exploitation of Coal, and Application of Quaternary and Tertiary Geology to Environmental Problems in a Carbonate Valley in Central Pennsylvania were presented as was an opportunity to visit an undolomitized Silurian coral-Bryozoan reef.
1983
Silurian Depositional History and Alleghanian Deformation in the Pennsylvania Valley and Ridge
Leaders:
R. P. Nickelsen and E. Cotter
This field conference examined the landscape of central Pennsylvania which is dominated by linear ridges and fertile valleys. For the Lower and Middle Silurian units, a pattern in the complex paleoenvironmental patterns that is related to Appalachian Basin configuration, source area tectonics, and sea-level fluctuations, were examined. Strain features which help explain the Alleghany Orogeny are also examined.
