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.
Mesozoic66 - 252.17 Ma | Mesozoic plutonic: undivided granitic rocks Plutonic: undivided granitic rocks |
Cretaceous66 - 145 Ma | Cretaceous 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. |
