Oct 23, 2019 (Sheree Hinz) - Lithology Comment The chert-ironstone unit is interbedded with mafic to intermediate metavolcanics, and is intercalated with metavolcanic-derived wacke interbeds. The ironstone unit is at least 6 km in length, and is aeromagnetically distinct. This unit appears to be discontinuous, because deposition probably occurred in basin-like features separated from each other or because of tectonic dislocation. The unit is probably at least 30 m thick, and may be as great as 50 m thick. The chert-magnetite banding forms laminae less than 1 mm thick and can be as much as 30 cm thick. The chert usually forms the thicker beds. Ironstone bands consist mainly of magnetite and amphibole
