What is the protolith of greenstone?

The protolith of greenstone is typically basalt or other mafic volcanic rocks. Greenstone is formed during the metamorphism of these volcanic rocks, often in a geological setting such as an ancient oceanic crust or during tectonic processes. The metamorphic conditions can lead to the formation of minerals such as chlorite, amphibole, and epidote, giving greenstone its characteristic green color.


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.


How is polonium extracted from the ground?

Polonium is a rare and radioactive element that is not typically extracted directly from the ground. Instead, it is usually produced as a byproduct of uranium or thorium decay in nuclear reactors. It is separated using chemical processes, such as solvent extraction or precipitation, from the other byproducts generated during nuclear reactions.
