Abstract The record of igneous activity (magmatism and volcanism) can significantly affect natural resource exploration and exploitation, including the search for hydrocarbons, critical minerals, natural hydrogen and geothermal energy sources, as well as using mafic igneous rocks as storage sites for CO 2 . These effects will vary depending on the nature and timing of the activity, the structural framework and the crustal architecture of the affected country-rock. To understand these effects and the interplay with other factors, we must first know the igneous record's distribution, timing, and petrology. In this paper, we describe a new geospatial database of the igneous rock record designed to provide a baseline digital resource that is application-agnostic and can be applied across the broadest range of research and resource exploration activities. We discuss the challenges we have faced and solved at each of the three main stages of geospatial mapping: database design, database population and database visualization. This includes the importance of a comprehensive audit trail so that users can differentiate between well and poorly-constrained interpretations, helping identify areas requiring additional work and data acquisition. The result is a geospatial database that will facilitate a better understanding of the Earth system and natural resource exploration.

ABSTRACT In order to address the most important Earth science questions, field scientists must incorporate new cyberinfrastructure (CI) technologies into their workflow and replace some of the traditional, analog methodologies that still prevail today (e.g., notebook, pen, and transit compass). Geologic field data collected via analog methods are far less likely to be fully digitized and integrated with other datasets. Cyberinfrastructure allows data longevity beyond the original investigator. Digital platforms that facilitate data sharing will help break down the artificial barriers between subfields within the Earth sciences and allow researchers to ask new types of questions and provide the means to contend with those that were previously unanswerable. Close communication and coordination between field-based geologists and computer scientists will facilitate the best cyberinfrastructure and data management for the future. Through a National Science Foundation (NSF)/EarthCube–funded project, discussions between these two groups of scientists were undertaken in a field setting so that computer scientists could better understand the type of data geologists collect and how those geoscientists desire to integrate various types of data into their workflow. Similarly, geologists gained a better understanding of how computer scientists can represent, manipulate, and archive complex data in data management systems, with potential solutions to field data challenges. These discussions centered on the unique issues faced by the geological community regarding the collection, storage, manipulation, representation, and integration of field-based data.
