Regional Geology

This information on rock units at or nearby to the coordinates given for this locality is based on relatively small scale geological maps provided by various national Geological Surveys. This data will improve over time as more accurate maps and data sets are added.

Holocene0 - 0.0117 Maalluvium 38485


Channel and flood plain alluvium; gravel, sand, silt, clay; may be locally calcreted

regolith; synthesis of multiple published descriptions

Silurian-Devonian358.9 - 443.8 MaSilurian-Devonian plutonic rocks

Plutonic rocks

Deep-seated to high-level intrusions are included. Many charnockites, anorthosites, and large ophiolites, classified as plutons, are distinguished in the database using the SIGNIF item. Ophiolites were classified as plutons, even where remnants may be extrusive and/or sedimentary.

Early Devonian - Ludlow393.3 - 427.4 MaSilurian to Devonian sedimentary rocks


Predominantly sedimentary rocks; includes sedimentary rocks of low metamorphic grade and diapiric breccias
