Global Granite Geochemistry and Outcrop Database (GGGOD)

The Global Granite Geochemistry and Outcrop Database (GGGOD) is a free, Open Access, userfriendly, Geographical Information System (GIS)-based resource allowing the visualization, plotting, and spatial analysis of all granitoid compositions that have been reported hitherto in various Open Access databases and publications. Data can be filtered by location, composition, and source using GIS vector analysis tools. For historical context, a general overview of the GGGOD map is provided in Figure 1 together with type localities and influential works published during the early history of granite science (18th and 19th centuries). Geochemical data is compiled from FAIR (Findable, Accessible, Interoperable, Reusable), Open Access initiatives (dataset modified after Gard et al., 2019). Granitoid outcrops are redrawn from the Global Litholoigcal Map (GLIM, Universität Hamburg; Hartmann and Moosdorf, 2012). Basemap: ESRI® Ocean.
