Rocks at asteroid impact site record first day of dinosaur extinction（图）
Rocks asteroid impact site record first day dinosaur extinction
2019/10/18
When the asteroid that wiped out the dinosaurs slammed into the planet, the impact set wildfires, triggered tsunamis and blasted so much sulfur into the atmosphere that it blocked the sun, which cause...
First GPS measurements across the Central-Western Mediterranean area
GPD Mediterranean geodynamics
