Similar to gold mining, diamonds can be separated from weathered kimberlite, known as yellow ground. Geologists call it an ultrabasic rock, which means it does not contain any quartz or feldspar, the two most common rock-forming minerals. If a conglomerate contains clasts of kimberlite, then the source of that kimberlite must be upstream of the location where the kimberlite clast was deposited. Geologists Carpenter and Russell studied Devils Tower in the late 1800s and concluded that the Tower was formed by an igneous intrusion (the forcible entry of magma through other rock layers).
