These blobs of material represent spray from melted rock that was liquefied in the impact, then rapidly cooled and hardened to form pebble-like glass objects, some the size of a pea and others as large as a golf ball, known as tektites.
The resulting tektite strewn field is one of only a handful discovered to date.
"I was very surprised!" geologist Álvaro Penteado Crósta of the University of Campinas in Brazil told ScienceAlert. "Tektites are a very rare material on Earth."
