What is the protolith for greenstone?
The protolith for greenstone is usually basaltic or andesitic volcanic rock that has undergone metamorphism, resulting in the formation of chlorite, epidote, and actinolite minerals that give greenstone its characteristic green color. These rocks are typically found in greenschist facies metamorphic environments.
