Alteration, slope-classified alteration, and potential lahar inundation maps of volcanoes for the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) Volcano Archive
Identifies hydrothermally altered volcanic edifices and vulnerable areas downstream by mapping alteration on volcanoes, highlighting lahar prone watersheds using Global Digital Elevation Model data, and modeling via a lahar flow-fill modeling program |

Depositional Setting and Geochemistry of Phosphorites and Metalliferous Black Shales in the Carboniferous-Permian Lisburne Group, Northern Alaska
The purpose of this paper is to present new sedimentological, paleontological, and geochemical data that allow us to define the geographic and stratigraphic extent and depositional setting of these temporally unusual phosphorites. |

Global Geochemical Database for Critical Metals in Black Shales
Geochemical data for stratigraphic rock sequences containing dominantly fine-grained clastic rocks with appreciable organic carbon (above 0.5 weight percent), usually known as 'black shale facies examples' but including all fine-grained clastic rocks such as argillite, mudstone, claystone, and their low-medium grade metamorphic equivalents. Data are provide in Microsoft Access and tab-delimited text formats. |
