It is What DDM-SVF Is and Is Not essentially a complete “geologic map Several attributes differentiate on disk” (CD-ROM). Because of its DDM-SVF from map-making systems digital format, the program contains on desktop computers (for example, far more data than even the most the Macintosh-based MiniCad maps complete analog maps.

CALL FOR PAPERS Theme Statement for 1995 Annual Meeting The theme for the 1995 Annual Meeting is Bridging the Gulf. This theme has several meanings. In particular, we will draw attention to the Gulf of Mexico–Caribbean, and the surrounding Ameri- can continents, bridging the knowledge gap that exists across a region divided by political boundaries and language but sharing a common geologic framework. Bridging the Gulf also addresses the need to develop a closer link between technology and the science of geology and to educate the public on issues critical to the development of intelligent policies on the environment and geologic hazards. We also hope to bridge the gulf between the past and the future with both a retrospection on the past 25 years of plate tectonics and a look at the future as geologists respond to society’s needs. Finally, we view the city of New Orleans, the Mississippi River and its delta, and the Gulf Coast as a laboratory where the long-term effects of humans on the environment can be examined.

A preliminary symposium schedule will be available from headquarters by May 15. S1. GSA Keynote Symposium: The Mississippi River—Control and Consequences. 1995 GSA Annual Meeting Committee. Shea Penland, Louisiana State University. Severe coastal land loss is destroying the Mississippi River delta plain at alarming rates; between the 1930s and 1990s more than 1500 square miles of wetlands were lost. Threatened is 40% of the coastal wetlands found in the United States. The coastal wetlands of the delta plain are extremely valuable to society due to fish and wildlife resources, storm protection, oil and gas production, environmental quality, and the lifestyle they afford. Coastal land loss is driven by natural and human processes. Sub- mergence and erosion are important natural processes of change. Flood and river control has accelerated the process of coastal land loss resulting in a net loss of land. Recognized as an environmental problem of national significance, the Coastal Wetland Planning, Protection, and Restoration Act of 1990 established a multimil- lion dollar program to save Louisiana’s wet- lands. This symposium looks at the effects of human development on the natural processes of change within the delta plain. In particular, this session focuses on the balance between the desire for a lifestyle based on flood protection and an industry-based economy along the river Hurricane Andrew courtesy of LSU Earth Scanning Laboratory.

VOLUNTEERED PAPERS This format includes all abstracts that are not specifically invited for a symposium. Each paper will have a minimum of three reviews. Two types of sessions are available: 1. Discipline Sessions Papers are submitted to ONE scientific discipline. The JTPC representatives organize the papers in sessions focused on this discipline, for example, hydrogeology. 2. Theme Sessions Papers are submitted to a specific pre-announced title and to ONE scientific category. Theme sessions are interdisciplinary; each theme may have as many as three categories from which authors may choose ONE. After each theme description below, the categories are identified by name and number as they appear on the 1995 Abstract Form. Theme submissions must include: Item Example • Theme number T18 • Key words of the theme title Methods for Quantifying Unsaturated Permeability • One category Environmental Geology—#6 on abstract form • Mode for the session Poster Please submit only in the mode indicated in the description (oral or poster) If the abstract is submitted in the incorrect mode, the abstract will NOT be considered for the theme session, but will automatically be considered for a discipline session instead. Role of theme advocate Each theme session has been proposed by an advocate. Advocates may not invite speakers; however, advocates may encourage colleagues to submit abstracts, with the understanding that there is no guarantee of acceptance. All abstracts will be evaluated by three appropriate JTPC reviewers in the discipline for which they are submitted; a fourth review will be provided by the theme advocate. During the August 11–12 JTPC meeting, the designated JTPC representative (in consultation with the theme advocate) will Courtesy of RockWare.

GSA TODAY, April 1995 Technical Program Schedule: September GSA Today 81 FIELD TRIPS

The theme of this year’s GSA Annual Meeting is “Bridging the Gulf,” and the field trips we will offer are in keeping with that spirit. The geology ranges from the volcanics of Mexico to the Paleozoic rocks of Alabama, and from mountains to the interior of a salt dome. Included will be Appalachian structure, salt dome tectonics, and stratigraphy from lower Paleozoic to Holocene. Environmental and land-use aspects will include delta building, coastal erosion, Mississippi River deposition and flood control, industrial water use and disposal, gravel quarrying, and agriculture. All this will be interspersed with the culture of an area rich with history: pre-Columbian Indian, Colonial, Cajun and plantation development, Civil War forts and battlefields, and one of our most lively and varied present-day populations. In all, we are offering a great variety. We have the leaders to take you to the best of our geology and to share with you their enthusiasm for it. Trips are led by active researchers and are technical in nature, although students are definitely encouraged to attend. All trips begin and end in New Orleans unless otherwise indicated. Trip costs are subject to Premeeting change before registration begins in June, but they are not expected to change significantly. If you register for only a field trip, you must pay a $25 nonregistrant fee in addition to the field trip fee. Explosive Volcanism and Pyroclastic This fee may be applied toward meeting registration if you decide to attend the meeting.

GSA TODAY, April 1995 91 Large Meteorite Impacts and Planetary Evolution edited by B. O. Dressler, R.A.F. Grieve, and V. L. Sharpton, 1994 Twenty-eight papers, organized in five chapters, cover a wide range Abstract of topics of interest to the planetologist and other geoscientists. Topics include impact cratering phenomena and processes, shock Forms metamorphism, the origin of tektites, terrestrial and planetary impact structures, and paleontological extinctions. Six papers present new Available data on the origin and evolution of the Sudbury structure of northern Ontario. Information on nine other terrestrial impact structures also is presented, including the Popigai and Puchezh-Katunki structures of Now Russia, the Vredefort structure of South Africa, and the Beaverhead structure of Montana. The six papers in the first chapter on Planetary Constraints and Perspectives are of special interest to the GSA planetologist dealing with the origin of lunar multi-ring basins, impact structures on Venus, and impact melt production on the Annual planets. Includes an extensive glossary. Meeting SPE293, 358 p., paperback, indexed, ISBN 0-8137-2293-4, $97.00 NOVEMBER 6–9, 1995 Elements of Pennsylvanian NEW ORLEANS, LA Stratigraphy, Central Appalachian Basin edited by Charles L. Rice, 1994 Nine papers synthesize the conclusions of ongoing paleontological studies of coal spores, macrofossils, and microfossils, including a preliminary zonation of Middle and Upper Pennsylvania conodonts in the central Appalachian basin, and establish a new Pennsylvanian stratigraphic framework for the basin. A biostratigraphic study is coordinated with the first well-constrained isotopic age developed for a Carboniferous horizon in North America. Component parts of key marine units are analyzed in terms of specific depositional environments within transgressive and regressive regimes. The papers name new stratigraphic units, reconcile old stratigraphic problems within and between the states by eliminating major miscorrelations, and demonstrate the correlation and continuity of key basinal biostratigraphic horizons. A cross-referenced glossary of both formal and informal stratigraphic terms provides what is essentially a comprehensive alphabetized correlation chart for the entire Pennsylvania System in the central Appalachian basin.
