http://schema.org/description

  • "A complexly faulted and folded sequence of Mississippian carbonate rocks more than 1,000 m thick is exposed in the northern Tendoy Mountains in southwest Montana. These rocks, previously assigned to the Madison Group, Big Snowy Group, and Amsden Formation, are herein referred to the Tendoy Group (new name) and the Snowcrest Range Group (new name, Wardlaw and Pecora, Chapter B, this bulletin). The Tendoy Group comprises, in ascending order, the Paine Limestone (raised in stratigraphic rank), Middle Canyon Formation, Mission Canyon Limestone (previously assigned to the Madison Group in this area), and McKenzie Canyon Limestone (new name). The Tendoy Group represents a hitherto unrecognized facies belt near the craton margin. The overlying Mississippian Snowcrest Range Group consists of, in ascending order, the Kibbey Sandstone (reassigned from the Big Snowy Group) and two newly named units, the Lombard Limestone and the Conover Ranch Formation (Wardlaw and Pecora, Chapter B, this bulletin)."
