The older xenolith, composed of diorite, is more resistant to weathering and erosion than the granodiorite that intruded into the diorite, so permitting the xenolith to protrude from the weaker granodiorite. • Both rocks are around 600 million years old. • Amazing! • #xenolith #herm #hermisland #diorite #igneous #granodiorite #feldspar #xenoliths
