SINHGE_190615_121.JPG: Cretaceous-Tertiary Boundary Layer
Beloc, Haiti
The greenish-black spheres in this specimen are impact melt from Chicxulub. The thickness of the layer and the spheres' abundance and size are consistent with the source crater being less than 1,000 km (625 mi) away.
SINHGE_190615_140.JPG: The light-colored clay layer in this cross-section marks the Cretaceous-Tertiary boundary. It contains several signs of impact: grains of shocked quartz, spheres of melted rock, and an unusual amount of iridium.
