  1. CYBERINFRASTRUCTUREFOR THE EARTH SCIENCES-Metamorphic Petrology and TectonicsM.L. Crawford, D. Mirante – Bryn Mawr College www.geongrid.org

  2. Project Goals To ask meaningful questions – and do ‘new science’ To retrieve and analyze data from disparate sources in order to address those questions. To produce a controlled vocabulary that can be applied to metamorphic and tectonic processes to assist in the goals above. To develop the infrastructure to serve the data analysis needs of scientists, educators, students, and the general public. www.geongrid.org

  3. Access - To develop databases as few data are currently available in digital format. Visualize - To identify and adapt smart tools for data analysis and presentation and make them widely available. Issues for metamorphic petrology www.geongrid.org

  4. Analyze - To develop access to computational resources for analysis Model - To encourage interactions through GEON to assist in development of tectonic models using petrological as well as other data. Issues for metamorphic petrology www.geongrid.org

  5. DEVELOP ONTOLOGIES HELP DESIGN DATABASE SCHEMAS FOR METAMORPHIC ROCKS COMPILE DIGITAL GEOLOGIC MAPS OF METAMORPHIC AND TECTONIC FEATURES - MidAtlantic MAKE THESE PRODUCTS AVAILABLE OVER THE WEB Current Bryn Mawr research activities www.geongrid.org

  6. Metamorphic Grade Metamorphic Processes Metamorphic Rocks www.geongrid.org

  7. Overview concept map for determining equilibrium via metamorphic petrology www.geongrid.org

  8. Areal distribution of data on maps. Minerals present Mineral and rock chemistry Rock textures and fabrics Mineral ages Experimental data Tectonic setting Types of data www.geongrid.org

  9. GIS mapping - using CARIS Tools - distribution of data on maps. www.geongrid.org

  10. ACCOMPLISHED Digitized detailed geological map - Northern mid-Atlantic www.geongrid.org

  11. Nested in this map are compilations of detailed information from the literature on petrology, structure and geochronology www.geongrid.org

  12. Zoom in on area of interest - showing sample sites www.geongrid.org

  13. Show on the map all the locations with kyanite and staurolite www.geongrid.org

  14. Graphical representations of phase equilibria -in this example related to the map just shown. Tools www.geongrid.org

  15. P • Identify all the areas on the phase diagram (outlined by mineral equilibrium curves) that contain both kyanite and staurolite. • Obtain PT data from the diagram. T and P of point indicated T www.geongrid.org

  16. Programs for calculating and displaying phase equilibria - obtain and serve programs developed elsewhere. Tools www.geongrid.org

  17. AX - (Holland) Bayes - (Chatterjee, Krüger, Haller, Olbricht ) CSpace - (Djinn Works) EQMIN - (Martin) Ge0-Calc - (Brown, Berman, Perkins) GIBBS - (Spear) GTB - (Kohn and Spear) Perplex - (Connolly) THERIAK-DOMINO - (de Capitani). WEBINVEQ - (Gordon) Programs - identified thus far www.geongrid.org

  18. Areal distribution of data on maps. Minerals present Mineral and rock chemistry Rock textures and fabrics Mineral ages Experimental data Tectonic setting Types of data www.geongrid.org

  19. 17 Tables Bibliographic Experimental Data Experimental conditions Starting material Mineral/glass chemical data (Plg, Grt, etc.) Database on rock melting experiments www.geongrid.org

  20. Query result: all glass compositions coexisting with garnet Experimental conditions Pressure, Temperature, fO2 H2O content Duration Apparatus Type of experiment Nature of starting material Bibliograhic Tables Person - data about author Institution - data about author locale Reference - data about the article Starting Material Oxide data Brief geological term Literature abbreviation or name Experimental data All phases described as end-products of an experiment. Modal abundance. Major oxide data. CIPW norms of glasses - www.geongrid.org

  21. Query result - all glass compositions coexisting with garnet - plotted on a standard petrological triangular diagram www.geongrid.org

  22. Query result - all glass compositions coexisting with garnet - plotted on a standard petrological triangular diagram Next - link garnet chemistry to each point on this diagram www.geongrid.org

  23. Sample ID issues - need a unique ID one sample may have many numbers or names in different publications different researchers may use the same sample number mentioned as a GEON priority PETDB is also working on this issue Issues that need to be addressed www.geongrid.org

  24. Near term Goals • Continue to develop a GIS-like system to relate tabular and spatial data beyond maps. • This can give textural context to published (and other) data, from the mineral and thin section scale to outcrop and regional scale. www.geongrid.org

  25. Near term Goals • Develop a GIS-like system to relate tabular and spatial data beyond maps. • maps integrated with chemical analyses, ages, etc. • hand sample images integrated with SEM images, analyses, x-ray maps, etc. as well as with the geological maps. www.geongrid.org

  26. Undergraduate students Graduate students Researchers General geologists Who is our audience? www.geongrid.org

  27. Work closely with the ISES Working group on developing and deploying a Database for Metamorphic Petrology. Future Plans www.geongrid.org

  28. Work closely with the ISES Working group on developing and deploying a Database for Metamorphic Petrology. Allow access to GEON ontology development and encourage the community to provide input and suggestions for improvements. Future Plans www.geongrid.org

  29. Develop a Geo-Informatics oriented curriculum at Bryn Mawr College in collaboration with the computer science department. Future Plans www.geongrid.org

  30. Integrate metamorphic data with data from igneous rocks and with sedimentological and paleontological information to develop a refined regional model for tectonic activity in the mid-Atlantic since about 1 Bya Where is this leading? www.geongrid.org

  31. Integrate metamorphic data with data from igneous rocks and with sedimentological and paleontological information to develop a refined regional model for tectonic activity in the mid-Atlantic since about 1 Bya Encourage colleagues and students to take advantages of the GEON resources for their research and teaching. Where is this leading? www.geongrid.org
