Why would anyone consider the Carancas impact a " Pit " ? Never heard of impact pits on the moon. Heard of impact pits on SA's.
The crater is " non - meteoritic " That doesnt make any sense. Are you suggesting that something other that the meteorite created the crater ? Please elaborate on that quote.
