lithogrid

LithoGrid is a precision-built mobile reference app for geologists, earth scientists, students, and anyone fascinated by the planet beneath our feet. Clean, fast, and uncompromising in its accuracy, LithoGrid delivers the complete scientific vocabulary of geology directly to your phone.

Powered by live data from Macrostrat—one of the most comprehensive open geological databases in North America—LithoGrid provides real-time access to curated, peer-reviewed data used by researchers worldwide.

No login. No subscription. No noise. Just science, beautifully organized.

Four Pillars of Geological Knowledge
LITH (Rock Types & Classifications): Browse the full spectrum of sedimentary, igneous, and metamorphic rocks. Each entry includes class, type, group, and official color codes for instant identification in the field or lab.

TIME (The Geologic Time Scale): From the Hadean to the Holocene, explore Earth’s deep time with Swiss precision. Every eon, era, and period is chronologically sorted with precise age boundaries in millions of years.

ENV (Depositional Environments): Quickly place any formation in its paleoenvironmental context. Catalog every known setting—from fluvial and marine to glacial and lacustrine—organized for rapid reference.

STRUCT (Geologic Structures): A definitive companion for structural interpretation. Access a complete library of folds, faults, joints, and unconformities organized by class and type.

Built for Serious Work
The design reflects the discipline: a minimalist, high-contrast "Swiss Style" aesthetic that ensures maximum readability. LithoGrid isn’t a static PDF or a bloated utility; it’s a lightweight, live connection to the latest earth science data.

Who Is LithoGrid For?
Field Geologists needing a fast, reliable reference in remote locations.

University Students studying stratigraphy, sedimentology, or structural geology.

Educators looking for a modern, visually compelling teaching tool.

Geo-enthusiasts who want deeper insights than a standard encyclopedia.
