The facts on the card
The card carries these facts from its Wikipedia article.
- The name comes from the green hue imparted by the colour of the metamorphic minerals within the mafic rocks: The typical green minerals are chlorite, actinolite, and other green amphiboles.
- Greenstone belts also often contain ore deposits of gold, silver, copper, zinc, and lead.
- A greenstone belt is typically several dozens to several thousand kilometres long.

Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Greenstone belt article was read about 22,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 60 and blocks with 34: each hit it takes is cut by 14 %.
