Description


Goat Paddock crater

Goat Paddock is a 5 km-diameter near-circular bowl-shaped depression in a range of gently dipping Proterozoic sandstone in the Kimberley Region of northern Western Australia, 106 km west-southwest of Halls Creek. It is interpreted as an ancient meteorite impact crater, the evidence including breccia containing melted rocks, silica glass, shatter cones and shocked quartz.[2][3] Drilling shows that the crater is filled with about 200 m of ancient lake sediments containing Early Eocene pollen, this age thus giving a minimum estimate for the age of the crater itself.[1] The crater is not perfectly circular, but slightly elongated in a north–south direction, suggesting that the projectile struck at low angle from either the north or south.
