The study, published in the current issue of the journal Antiquity, indicates that two quarries in the Preseli Hills of Pembrokeshire, in southwest Wales, are the source of Stonehenge’s bluestones.

The very large standing stones at Stonehenge are sarsen, a local sandstone. The smaller ones, known as bluestones, consist of volcanic and igneous rocks, the most common of which are called dolerite and rhyolite.
Geologists have known since the 1920s that the bluestones were brought to Stonehenge from somewhere in the Preseli Hills, around 140 miles from Stonehenge. But the outcrops of Carn Goedog were only recently identified as the main source of Stonehenge’s dolerite and Craig Rhos-y-felin as the source for the rhyolite bluestones.
The new research focused specifically on the Craig Rhos-y-felin outcrops.
