Key Takeaways
- Jurassic-era pink granite boulders in Antarctica's Hudson Mountains traced to a buried 100km-wide granite mass beneath Pine Island Glacier
- Airborne gravity surveys confirmed the structure is roughly 7km thick and was previously unknown to geologists
- The granite body's heat-generating radioactive elements could influence basal melting rates and ice sheet flow models
