Decoding mysterious seismic signals

An outcrop called ‘the Bubble’ on Eileach an Naoimh (Holy Isle). It shows a huge white rock fragment, tens of metres across, which was originally part of the underlying rock sequence. The layering in the carbonate rock has been squeezed tightly under immense pressure and transported by thick ice sheets to its final resting as one of many different rock fragments within a moraine.

Dark bands are iron oxides (magnetite, hematite) and yellow-orange bands are chert with iron oxide inclusions (jasper). (Photo by Linda Welzenbach-Fries/Rice University)
