The crystal, It was his hope that a graduate would find the source kimberlite pipe. Kimberlite is unique because it originates over 100 miles (150 km) deep in the earth and travels in a matter of hours to the earth's surface where it forms small volcanic features. Botanists and geologists have long known that certain plants have evolved to grow on specialized soils. The soil appears at the top of pipes, or tubes, of the igneous rock which has been pushed to the surface from an underlying source of magma, carrying rocks and minerals—including diamonds—to the surface. The world average odds of success, i.e. MAPS; Advertise. diamonds in Wisconsin was discovered in 1888 near the Green Lake Moraine and is known as source of the diamonds. “The pipes appear to have formed by a two-stage process: (1) pipe excavation, where a large hole is blown out of the ground, and (2) pipe infilling, where kimberlite lava and ash fill up the hole. Considering the combination of the small size of the kimberlite pipes, and the fact that nearly all of the Lake Superior region is covered with glacial deposits, it is not surprising that the potential source of the diamonds remained unknown for many years.
