66 - 145 Ma
|Cretaceous plutonic rocks|
Age: Cretaceous (66 - 145 Ma)
Comments: 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.
Lithology: Plutonic rocks
