Ely Greenstone is a type of greenstone found in the Ely Greenstone Belt in northern Minnesota. It is a metamorphosed volcanic rock that is around 2.7 billion years old, making it one of the oldest rock formations on Earth. Ely Greenstone is known for its unique color and mineral composition.
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.
West Coast, South Island, New Zealand!
Greenstone is the stone highly valued by Maori and considered sacred. It is a type of jade and is called 'Pounamu' in Maori. It is extremely hard ; it is harder than steel. It was used to make highly prized tools and weapons but now is mainly used to make jewellery and other decorative items. it is mainly found in the remote river valleys of the Southern Alps and Westcoast areas of the South Island of New Zealand.

Nephrite, greenstone or Pounamu was traded between the southern and northern parts of New Zealand. It is mainly found on the west coast of the south island. Similar stone is found in the Americas and in China, and as it is valued for its toughness and fine finish, no doubt it was much traded there as well.
Greenstone can be found in regions with geological formations that have undergone metamorphism, such as New Zealand, Canada, and parts of the United States. It is often associated with regions that have a history of volcanic activity and tectonic processes that have produced the necessary conditions for its formation.
