Geographical Extent
The Abitibi greenstone belt is one of the world's largest Archean greenstone belts. It appears to represent a series of thrusted subterranes that exhibit similar geological, geochemical, and isotopical signatures as those formed during the evolution of paired active-arc-back-arc systems. The huge 2,707-2,696 million year old Blake River Megacaldera Complex is within the belt.

Famous quotes containing the words geographical and/or extent:
“While you are divided from us by geographical lines, which are imaginary, and by a language which is not the same, you have not come to an alien people or land. In the realm of the heart, in the domain of the mind, there are no geographical lines dividing the nations.”
—Anna Howard Shaw (1847–1919)
“The English did not come to America from a mere love of adventure, nor to truck with or convert the savages, nor to hold offices under the crown, as the French to a great extent did, but to live in earnest and with freedom.”
—Henry David Thoreau (1817–1862)
