They contain a percentage of sedimentary rocks which are intermingled with various volcanic rocks and volcanic rocks.
A rock commonly found in the Greenstone belts are conglomerates. If you find conglomerates there is a high percentage of gold in the region. They are known a gold rocks. The Abitibi in the Canada greenstone belt contains a high percentage of conglomerates. Greenstone belts are not the same size. They vary in type and length.
