Use "astrobleme" in a sentence
"Another earthquake spot is on the north shore of the St. Lawrence River, most interestingly just in a large meteorite impact structure ( "astrobleme") called Charlevoix."
"A comprehensive comparative analysis with other complex meteorite impact structures demonstrated that it is the oldest, the largest and the only example on earth providing a full geological profile of an astrobleme below the crater floor, thereby enabling research into the genesis and development of an astrobleme immediately post impact."
"It provides the only mappable and restorable profile that illustrates the genesis and development of an astrobleme during the very short time after impact."
