For much of its geologic history South America was part of a supercontinent comprised of many southern hemispheric landmasses South America began to split apart from Africa 130 million years ago and separated from Antarctica within the past 50 million years At 6 88 million square miles it is the fourth largest continent on Earth.
The largest single source of byproduct gold in the United States is the porphyry deposit at Bingham Canyon Utah which has produced about 18 million troy ounces of gold since 1906 Geologists examine all factors controlling the origin and emplacement of mineral deposits including those containing gold.
