Abstract

Mafic and ultramafic rocks are prospective lithologies for hosting critical minerals and carbon mineralization. Starting 2023, the Virginia Department of Energy has participated in multiple federally funded projects to characterize these resources through geologic mapping, sampling, and resource assessment. To improve data accessibility, integration, and visualization, we developed two interactive ArcGIS Experience Builder applications that compile published statewide geologic mapping and sample-based datasets for mafic and ultramafic rocks. The applications highlight various mapping products, including statewide compilations of mafic and ultramafic units, quadrangle-scale geologic maps, and new maps created from the funded projects, providing a multi-scale framework for understanding the geologic context of these units. In addition, these applications represent our sample inventories and databases, integrating Virginia Energy's rock repository and newly collected materials from projects. Users can explore sampling sites, lithology, analytical results, and metadata through interactive maps, images, databases, and built-in tools. The applications provide a centralized, dynamic platform for visualizing and querying Virginia’s mafic and ultramafic datasets, supporting future research, project planning, and decision-making by a broad range of stakeholders across partner organizations.
