  <dc:description>&lt;p&gt;&lt;span&gt;With advances in web applications, organic&amp;nbsp;petrography&amp;nbsp;and other related disciplines are in need of updated online resources and educational tools to aid professionals and students in the identification and interpretation of macerals. The U.S.&amp;nbsp;&lt;/span&gt;Geological Survey&lt;span&gt;&amp;nbsp;(USGS) Organic&amp;nbsp;Petrology&amp;nbsp;Laboratory along with USGS Eastern&amp;nbsp;Energy Resources&amp;nbsp;Science Center&amp;nbsp;Information Technology&amp;nbsp;staff have developed five web atlases containing images of organic matter in geologic materials: 1. an American Society for Testing and Materials (ASTM) Atlas, 2. an Organic Petrology Taxonomy for International Classification (OPTIC) of&amp;nbsp;Coal&amp;nbsp;Macerals Atlas, 3. an Interactive Gulf Coast&amp;nbsp;Photomicrograph&amp;nbsp;Web Atlas (I-Map), 4. an Organic Material in&amp;nbsp;Shales&amp;nbsp;Atlas (Shale), and 5. an interactive Blue/White/Ultraviolet (UV) Light Atlas (Light). Each web atlas contains images of macerals with associated sample and petrographic data collected by the USGS. These webpages will provide means to preserve and circulate petrographic data collected by the USGS for coal and shale samples from all over the world.&lt;/span&gt;&lt;/p&gt;</dc:description>
