Geologic mapping | Creation of maps depicting geological characteristics of the earth's surface, including lithology, geologic structure, age, and the results of crustal processes. |
Geophysics | Airborne geophysical surveying, including measurement of magnetic anomalies, gamma ray emissions, gravity anomalies, and gravity gradient anomalies, and more detailed electromagnetic measurements of the area under the flight lines. |
Lidar | Light detection and ranging, an airborne, spaceborne or ground-based laser-ranging technique commonly used for acquiring high-resolution topographic data. |
Geochemistry | Chemical techniques used to identify the composition of rocks and unconsolidated deposits supporting geochemical reconnaissance surveys or geologic mapping. |
Reconnaissance geochemistry | Chemical techniques used to identify the composition of rocks and unconsolidated deposits supporting geochemical reconnaissance surveys. |
3D geological model | 3D geological model developed from geophysical, geochemistry, lidar and subsurface (borehole) data complementing geologic mapping. |
Mine waste | Mine waste analysis products to determine the potential of mine features to host critical minerals developed from geochemical analysis of mine waste samples (rock and water). |
Hyperspectral | Hyperspectral data collected with the NASA AVIRIS (Airborne Visible InfraRed Imaging Spectrometer) sensors and one of several thermal infrared (TIR) sensors (e.g., NASA’s HyTES and/or MASTER instruments) to produce derived mineral maps and other derivative data to aid in geologic mapping and mine waste sampling efforts. |

The data are intended to support these uses: show the nature and scope of scientific studies carried out using funds of the Earth MRI so that the effectiveness and value of those expenditures can be assessed; enable scientific researchers to determine what work is in progress so that they can plan to make effective use of the results generated by the studies when they become available; enable managers of scientific organizations to determine the locations where additional scientific work will be needed so that they can develop proposals to carry out studies that supplement and follow up on the work described here. Accordingly, the geographic information is provided with accuracy and resolution less than a kilometer of mapping or geophysical survey boundaries. Criteria for lidar survey boundaries are less clear. Details of project dates are as provided during the proposal process, and dates are given to the nearest year.
