Machu Picchu: Ancient Incan sanctuary intentionally built on faults

Photographs of alkaline magmatic intrusions in Greenland. The region was volcanically and tectonically active around 1.2 billion years ago. Although no longer active, it is of major interest to geologists because the subsequent uplift and glacial erosion have cut deep into the rift and exposed the magma chambers that once lay well below the surface. Greenland’s magmas were sourced from a mantle that was enriched and contaminated by ancient crustal materials. Credit: University of St Andrews
