Материал из Онлайн справочника
Шаблон:Infobox rockunit The Bull Arm Formation is a volcanic formation cropping out in Newfoundland, the youngest of the Musgravetown Group.[1] It is defined as everything between the first and last volcanic horizon, with a recognition that some sandstones will be interbedded, and its start and finish may vary across the region depending on how widespread volcanic horizons are in practice.[2]
