The Vista Alegre crater is a meteorite crater in Coronel Vivida, Paraná State, Brazil.[1] On the surface it appears as a circular, relatively flat plain within otherwise hilly terrain.
Description
It is 9.5 kilometres (5.9 mi) in diameter and the age is estimated to be less than 65 million years (Paleocene or younger).[1] More recently, a date of about 115 Ma has been given[2] and closer to the age of Vargeão Dome. Considering the proximity of location, age, and stratigraphic similarities of Vista Alegre and Vargeão, it has been proposed that it was a double impact.[3]
