Geological formation in Canada
TheKanguk Formation is a geologicalformation in theNorthwest Territories andNunavut ,Canada whose strata date back to theLate Cretaceous .[ 2] [ 3]
It was first described in the Kanguk Peninsula of theAxel Heiberg Island , along the shore of the Stand Fiord by Souther in 1963.[ 4] Queen Elizabeth Islands .
The Kanguk Formation is composed of darkshale andsiltstone with interbeds ofsandstone ,bentonite andtuff .[ 1] conglomerate beds occur in the western reaches inEglinton Island .
The Kanguk Formation preserves an extensive record of shelf assemblages rich in benthicforaminifera that reveal numerous pulses of localhypoxia .[ 5] Fish fossils have been unearthed here.[ 6]
