Stonehenge: Acoustic Bluestones Transported 260 km Because They RING

Tested 1,000+ rocks at Carn Menyn Ridge, Preseli.
5-20% of rocks produce metallic sounds when struck
— "bells, gongs, and tin drums."
Stones AT Stonehenge still ring after millennia.
The monument = "prehistoric glockenspiel."

Preseli dolerite (spotted): mafic igneous rock
Contains secondary QUARTZ from metamorphism
(clinozoisite, zoisite, albite, muscovite + quartz)
The quartz content gives the stones their
piezoelectric and sonorous properties.
Sarsen stones (main circle): silicified sandstone
= primarily QUARTZ (SiO2). Piezoelectric.

Blick Mead spring: 1mile east of Stonehenge.
Consistent 10-13C year-round (never freezes).
Sacred since ~8000 BCE (Mesolithic occupation).
35,000+ worked flints, aurochs bones (200-person
feasts), continuous use for 4,000 years BEFORE
Stonehenge was built.
The spring PRECEDED the monument by millennia.
The sacred water site attracted the stone temple.

Pilgrimage destination from across Britain.
Cremation burials within the monument.
Ritual feasting evidence (animal bones).
Solstice alignment (like Newgrange, Mnajdra).
