Mineral Commodity Summaries
Sophia L Background:
The U.S. Geological Survey (USGS) Mineral Resources Program (MRP) and the National Minerals Information Center (NMIC) conduct national and international assessments of the supply of and demand for mineral resources essential to the U.S. economy and national security. MRP and NMIC generate mineral resource assessments with many detailed spatiotemporal datasets on a regular basis to provide decision makers with the information required to ensure that the Nation has an adequate and dependable supply of minerals and materials to meet its defense and economic needs at acceptable costs related to environment, energy, and economics. 
The wealth of historical mineral reports and legacy data related to mineral extraction, consumption, and economics are hidden within tables, basic charts, and static maps published as PDF files and some XLSX files.
Solution Needed:
  • Provide recommendations on how these mineral resources datasets could be better organized, architected, and presented to make it easier to produce visualizations and to tell better stories about critical minerals.
Importance of Project:
Critical mineral resources provide implications that impact agriculture, communications, construction, mining and metal processing, consumer goods, health services, military, and transportation as well as the interdependencies between countries for mineral resources. Rare earth elements are increasingly important in electronic devices used in the defense, alternative energy, and communications industries. The lifecycle of developing, using, and disposing mineral commodities can have an impact on the environment, energy, and economy domestically and internationally.

Geologic Map of Alaska 
Sophia L Problem:
The Alaska Geology Revealed poster map is a generalization of the thousands of individual rock units into 39 geologic units. However, this map is just one derivative of the Geologic Map of Alaska containing a rich compilation of historic geologic maps of Alaska. The printed version of the Geologic Map of Alaska has about 220 geologic units and the database has about 450 geologic units, each of which represents the compilation of more than 15,000 map units in the attached database. Even with the generalized geology, the sheer complexity of Alaskan geology remains evident. It is difficult to visualize, explore, and analyze all the geologic data simultaneously. 
The printed version of the Geologic Map of Alaska is the traditional way the USGS publishes and makes geologic map data available to the scientific community and the public. However, static media like posters and PDFs make it difficult to interact and explore complex datasets spatially. The geospatial databases and interactive ArcGIS map document are newer types of publications, but they may not be easily accessible and discoverable to our users and potential users.  An online web interactive version of the Geologic Map of Alaska is coming soon and will hopefully provide a more accessible way to view and use the geologic data. USGS also began to examine QGIS to make the geospatial data available in a non-proprietary format. However, QGIS does not have a native format and is focused more on using shapefiles, which would not fully depict the rich compilation of geologic map data of Alaska.
Solution Needed:
  • Make the Geologic Map of Alaska more accessible and usable by publishing the database in open data portals and using open geospatial platforms.
  • Imagine and brainstorm different ways to communicate the richness and variety of Alaskan geology.
Importance of Project:
Alaska is a rich storehouse and mineral and energy resources for the country as well as a place where the effects of climate change are being felt every day.  Yet in most people’s imagination, it is a magical place, renowned for its scenery (mostly geologically based), charismatic wildlife, and pristine environment. These geologic maps of Alaska provide the basis to help us understand where potential mineral deposits and energy resources might be found, define ecosystems, and teach us about the earth history of the State. 
The Geologic Map of Alaska covers the entire state and reflects more than a century of work by a host of geologists and a compilation of two decades of work that began in September 1996. An ongoing iterative process was used to describe and correlate individual geologic units to produce the units for this statewide map and its interim products—a series of regional geologic map compilations—which were released as the process continued. As additional geologic data were acquired, previously released data, correlations, and interpretations were updated as needed. This Alaska compilation is unique in that it is integrated with a rich database of information provided in the spatial datasets and standalone attribute databases. Within the spatial files every line and polygon is attributed to its original source; the references to these sources are contained in related tables, as well as in stand-alone tables. Additional attributes include typical lithology, geologic setting, and age range for the map units. Also included are tables of radiometric ages.
The Alaska Geology Revealed map, a derivative of the Geologic Map of Alaska shows a  generalized view of geology of Alaska, which helps us understand the larger features of Alaskan geology and therefore where potential mineral deposits and energy resources might be found, helps to define ecosystems, and ultimately, teach us about the earth history of the State. Rock units are grouped in very broad categories on the basis of age and general rock type. This product represents the simplification of thousands of individual rock units into just 39 broad groups.
The Reconnaissance Surficial Geologic Map of the Taylor Mountains Quadrangle, Southwestern Alaska and accompanying digital files are the result of the interpretation of aerial photographs from the 1950s as well as more modern imagery. This map is also a derivative of the Geologic Map of Alaska databases and simply represents a different perspective and view of the data.  Limited new field mapping in the area was conducted as part of a mapping project in the Dillingham quadrangle to the south; however, extensive aerial photograph interpretation represents the bulk of the mapping effort. The accompanying digital files show the sources for each line and geologic unit shown on the map. In a number of areas, the features have been reinterpreted and the linework revised. A major difference between the maps is the recognition of much more extensive glacially dammed lake deposits and reassignment of some glacial deposits to different glacial events.

Other Notes:
Compilation of the Geologic Map of Alaska was complex because the original source maps were made by different generations of geologists, mapping with very different ideas. Many of the maps were completed before the concepts of accreted (suspect) terranes or even plate tectonics existed. Nonetheless, they generally represented reliable ground-truth.  On the other hand, some of the more recent maps were so governed by terrane analysis that conventional stratigraphic nomenclature was not used or literally, what the rocks were is obscured. We adopted a traditional stratigraphic approach and avoided use of the sometimes controversial and commonly inconsistently defined or applied terrane terminology.  We were especially fortunate in having the assistance of more than a dozen Emeritus scientists, having between them centuries of geologic experience in Alaska.  We did our best to resolve conflicting interpretations and map data from the regional compilations and from the individual source maps in areas where regional compilations had not been produced. We made every effort to preserve the original geologic map information, incorporating, where available, new data, but we were careful to not over interpret the geologic data. Yet even our willingness to make interpretations and revisions did not enable us in some areas to resolve mapping conflicts or to reconcile different mapping styles. Therefore, there are several areas on the map where map units are separated by “quadrangle boundary faults.” More data and fieldwork may allow resolution of these conflicts.  The database was designed to be a “living” database, expecting the ongoing incorporation of new data and allowing for different or revised interpretations

Multi-Resource Analysis in Madagascar
Sophia L Problem:
Scientists conducting Multi-Resource Analysis (MRA) need visualization tools to explore multiple datasets and conduct complex analyses across multiple resource assessments to better inform decision-making from an interdisciplinary perspective. The resource assessments in Madagascar were conducted in collaboration with the World Bank to determine if there are enough mineral resources in Madagascar to build a port that can drive economic development. Being able to blend at least three data layers together and dynamically control the transparency of each layer would be very useful for enabling on-demand interactive data exploration of multiple resource assessments.
Solution Needed:
  • Create a data visualization and exploration tool that allows non-domain expert explore the dataset and integrate other datasets to discover unexpected trends.
  • Build a publicly available open source multi-resource assessment tool that supports data exploration and discovery.
  • Create a tool that allows the user to control the transparency of three or more map layers through a ball in a triangle or polygon that allows for more refined control over which map layers to be more or less transparent.
The geospatial data generated from the “Study of the Future Impact of Minerals, Hydrology, and Ecology on the Integrated Economic Development in the Anosy Region, Madagascar” project is intended to inform decision-making on socio-economic and community development planning. The main objective of the project was to enhance the knowledge of minerals-related development in the Anosy Region and to provide information that could help with creating a sustainable economic development model. The information and data for the project was spatially integrated in order to identify development opportunities and infrastructure needs that would support or complement mining. Detailed results of the geologic, metallogenic, geohydrologic, ecologic, economic, and development land planning studies are included.
Importance of Project:
Natural resources seldom occur in isolation with respect to one another. Controversies often emerge around perceived environmental, economic, and societal needs and values. New and innovative approaches are necessary to delineate natural resources, characterize interactions among resources, engage stakeholder concerns and participation, and strike a balance among competing resource interests. Land managers, policymakers, and legislators are making greater use of assessments that identify and evaluate the compatibilities and conflicts associated with resource conservation and development opportunities. The ability to rapidly and accurately integrate and synthesize multi-resource information in an unbiased, judicious manner is fundamental to supporting and facilitating decision-making.
This integrated and multidisciplinary mineral resource assessment makes a positive contribution to the on-going planning and development activities in the Anosy Region. An effective regional development strategy will not only require analysis of the mineral potential, but will require integration across all orientations or sectors, such as agriculture, tourism, and fisheries development, as well as conservation, restoration, and social and physical infrastructure improvements.
