What is New


This "What's New" page will provide news on materials submitted to the website.
  • The Arabian Intrashelf Basins page compiled by Christopher Kendall from recent publications on Jurassic and Cretaceous sediments of Arabian Gulf. Links include recent meeting posters on ISBs from Geo Bahrain, AAPG Houston and SEPM Junction, Colorado. Tracks how ISBs formed when periods of platform carbonate accumulation were interrupted by rapid relative sea level rise and platform margins retreated a distance onto adjacent platforms forming new margin. The new margin aggraded and prograded towards the earlier platform margin's position while seaward local carbonate accumulated catching-up with sea level rise forming a barrier which isolated the intrashelf basin (ISB) (2/27/2015).
  • Santa Margarita and Vetter/Jewett Sands Exercises contributed by James S. Hewlett and Robert S. Tye. The two exercises are focused on recognition and interpretation of stratigraphic stacking patterns from seismic and wireline-log data from the San Joaquin Basin of California. Synthetic seismograms and facies associations are provided for an integrated stratigraphic interpretation (2/27/2015).
  • The first part of an introduction to Paleontology based on text written by Dr. Marcelle K. BouDagher-Fadel of the University College of London on Benthic and Planktonic foraminifera. These pages are for those who need an introduction to paleontology, particularly undergraduate and graduate students of Geology and Paleontology. Pages focus on foraminifera from different time periods in the Paleozoic, Mesozoic and Tertiary, providing simple, easy to read summaries for the most significant family of each large benthic foraminifera suborder (3/12/2014).
  • New introduction to exercise images and solutions recommending electronic media be used with exercise materials using Power Point as a drawing tool to solve the exercises' objectives. This use of Power Point provides an effective and easy way to handle the exercises while exchanging results in open and constructive dialogues between the class and the instructor (12/15/2013).
  • Chemostratigraphy Power Point Lectures kindly assembled and donated by Charlotte Schreiber, describe a History of stratigraphy, Atmosphere Evolution, Ocean Evolution and explain the uses of Radioisotopes, Carbon isotopes, Sulphur isotopes, Oxygen isotopes, and 87Sr/86Sr isotope Ratios (6/19/2013).
  • Geological Evolution of Virginia and the Mid-Atlantic Region consists of a series of of pages introducing the geology of the Appalachians that was created and assembled and then donated by Lynn Fichter of James Madison University (6/19/2013).
  • Image Galleries are now all displayed using "Galleria". The images are accessed by clicking on the horizontal carousel of thumbnails or the arrows on the larger image displayed above. Full screen images can be viewed by double clicking on this large display. This means that images displayed at a large scale can be viewed collectively by those around a computer screen or as a projected image in a classroom or lecture hall (1/ 26/2013).
  • Heron Reef and Low Isles Reef Galleries, representing two buildups in the Great Barrier Reef Australia, illustrated by Tracy Frank with her photographs and diagrams those of other authors. Low Isles is very different from Heron – located on the inner shelf and within reach of river flood plumes, a characteristic of the northern part of the Great Barrier Reef system (7/22/2012).
  • "Carbonate source rocks" relates how Holocene cyanobacterial mats and lime muds provide links to Middle Eastern Phanerozoic and earlier carbonate source rock potential and could be a topic future research (5/22/2012).
  • A Compilation of Phanerozoic sea-level change, coastal onlaps and recommended sequence designations provided by John W. Snedden (Inst. Geophysics UT Austin) and Chengjie Liu, (ExxonMobil Exploration). These curves are derived from Haq and Schutter (2008) and that for the Mesozoic-Cenozoic are from Hardenbol et al (1998), with minor revisions to accommodate absolute age revision and redefinition of stages (4/10/2012).
  • The SEPM STRATA site launched with new format, while materials on site remain open domain under the Creative Commons license:  http://creativecommons.org/licenses/by-sa/3.0/   (4/4/2012).
