A new microkrystite spherule-bearing diamictite is reported from below the impact spherule-bearing 3.47 Ga Antarctic Chert Member (ACM) at the base of the Apex Basalt, central Pilbara Craton, Western Australia [1,5]. The diamictite, defined as ACM-S2, consists of 0.6-0.8-m-thick spherule-bearing pebble to cobble-size chert-intraclast conglomerate separated from the main ACM-S3 by a ∼200-m-thick dolerite and ∼30-m-thick felsic hypabyssals. The microkrystite spherules are discriminated from...[Show more]
