GMEG - Geology, Minerals, Energy, & Geophysics Science Center
     |
Scientists with the GMEG Science Center work on issues related to geologic processes and mineral and energy resource potential, primarily in the western United States. The science staff includes geologists, geophysicists, geochemists, biologists, GIS and remote sensing specialists who are located in offices in several states.Select a topic below for project and publications information |

Porphyry Copper Assessment of Southeast Asia and MelanesiaThe U.S. Geological Survey collaborated with member countries of the Coordinating Committee for Geoscience Programmes in East and Southeast Asia (CCOP) on an assessment of the porphyry copper resources of Southeast Asia and Melanesia as part of a global mineral resource assessment. The region hosts world-class porphyry copper deposits and underexplored areas that are likely to contain undiscovered deposits. Examples of known porphyry copper deposits include Batu Hijau and Grasberg in Indonesia; Panguna, Frieda River, and Ok Tedi in Papua New Guinea; and Namosi in Fiji.

BIGFOOT: BIG-storm FOOTprint on California and future hazardsThrough a series of geomorphic process maps highlighting landscape responses to such big storms, GMEG scientists aim to tie the spatial patterns of geology and tectonics, landsliding and erosion, fluvial and alluvial responses, and onshore/offshore records of sedimentation. |

Geologic framework of the Northern Great BasinThe Great Basin is rich in mineral and energy (primarily geothermal) resources, nearly all of which are located on Federal land open to exploration (mostly BLM and US Forest Service). Nevada alone is the world’s 4th leading gold-producer, and mines in the northern Great Basin are major producers of barite, silver, and copper. The region is being actively explored for lithium and rare-earth elements. High heat flow and active faults make the region rich in potential geothermal resources—Nevada has ~450 megawatts of installed capacity and is being intensely explored for more— and the faults themselves pose a hazard to lives and property, with the most recent damaging earthquake (magnitude 6.0) occurring in 2008 near Wells, Nevada. |

Ecological and Toxicological Impacts of Metal Mixtures in Mineralized Rock DrainageWater Quality and Aquatic Life Standards that are set by federal and state regulatory agencies are used to evaluate the quality of our nation’s water and the health of aquatic ecosystems. These standards currently are based on hardness of the water and are determined for single metals, not for mixtures of metals that are typically found in natural systems. Metal mixtures potentially can be more or less toxic or have the same toxicity as single metals to aquatic organisms. However, models that predict the toxicity of metal mixtures to aquatic organisms are in their infancy. This project examines and models the effects of dissolved metal mixtures on the health of aquatic organisms. The metals of interest are cadmium (Cd), copper (Cu), and zinc (Zn) at concentrations and ratios that are present in drainage from mineralized ore deposits.
