The updip Frobisher beds subcrop (an underground outcrop) in Saskatchewan where they were eroded during the early Mezosoic. Sediments were deposited on top of the exposure making it a subcrop. Generally the beds thin in this direction and are often targets of exploitation because of petroleum accumulation.
Also below the Frobisher beds there is a regional unconformity of Mississippian age between the Frobisher and the Alida beds or in some areas he Kisbey sandstone.

What type of unconformity is present below the conglomerate?
Apologies, but I do not know what unconformity you are referring to. However, I can tell you that conglomerate IS present as an unconformity in many cases due to the nature of it's formation. Conglomerate is often produced during a flash-flood, so all rock strata from the period appear interrupted by the unconformity of Conglomerate which was deposited very quickly, then after burial was cemented and lithified. My answer, therefore, is that conglomerate is common as an unconformity.
What is the relative age of fault or igneous intrusion that cuts through an unconformity?
If a fault or intrusion cuts through an unconformity, the fault or intrusion is younger than all the rocks it cuts through above and below the unconformity.
What is the relative age of a fault or igneous intrusion that cuts through an unconformity?
If a fault or intrusion cuts through an unconformity, the fault or intrusion is younger than all the rocks it cuts through above and below the unconformity.
What are recognition of unconformity?
Recognition of unconformity can be presence of conglomeratic bed at the interface. It is fossils of wildly different ages which mark the variation of attitude.
What is the difference between angular unconformity disconformity and nonconformity?
Angular unconformity is when rocks are deformed and then eroded and then new sediment is deposited on top. Disconformity is when igneous or metamorphic rocks are eroded and then sediment is deposited on top. Nonconformity is when either there is no deposition for some time and then deposition resumes or horizontal layers are eroded (but not deformed in any way) and then deposition resumes. These create gaps in the rock record.
What is conformity in geology?
where the beds follow the same pattern of dip the opposite is an unconformity where the beds dip at different angles
A disconformity is an erosional unconformity with parallel beds or strata above and below?
True
What is an angular unconformities?
An angular unconformity is a type of unconformity in which a sedimentary stratum is deposited on top of another stratum which has been significantly tilted and subsequently eroded flat.
What is the angular unconformity?
Tilted strata lie below the unconformity; bedding in younger strata above is parallel to the unconformity.
Beds one on top of each other as a word?
Bunk beds
What are beds on top of each other called?
Ummm... bunk beds...
What is the definition angular unconformity?
Tilted strata lie below the unconformity; bedding in younger strata above is parallel to the unconformity.
An unconformity that results when new sediments are deposited on eroded horizontal layers is a?
A Disconformity, an unconformity between parallel layers of sedimentary rocks which represents a period of erosion or non-deposition.Types of Disconformity:A Paraconformity is a type in which the separation is a simple bedding plane; i.e., there is no obvious buried erosional surface.A Blended unconformity is a type with no distinct separation plane or contact, sometimes consisting of soils, paleosols, or beds of pebbles derived from the underlying rock.
Which unconformity has layers that are perpendicular to each other?
Angular unconformity :D
What name is given to layers of tilted rocks that are overlain by younger more flat lying rock layers?
angular unconformity
Who were martin frobisher's siblings?
Martin Frobisher had two siblings: a brother named John Frobisher and a sister named Joan Frobisher.
Which of the following best characterizes an angular unconformity?
Tilted strata lie below the unconformity; bedding in younger strata above is parallel to the unconformity.
