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 else can I help you with?
What general term denotes a buried erosional surface where rock layers are missing?
unconformity
What is the relative age of a fault or igneous intrusion that cuts through an unconformity?
The relative age of a fault or igneous intrusion that cuts through an unconformity is younger than the unconformity but older than the rock it cuts through. This is because the fault or intrusion must have formed after the deposition of the rock layers below the unconformity but before the deposition of the rock layers above the unconformity.
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 type of event has to occur to create an angular unconformity?
An angular unconformity forms when older tilted or folded rock layers are eroded, creating a flat surface. New horizontal layers are then deposited on top of this surface, resulting in an angular discordance between the older and newer rock layers.
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.
A disconformity is an erosional unconformity with parallel beds or strata above and below?
A disconformity is a type of unconformity characterized by erosion or non-deposition of layers of rock, resulting in parallel layers above and below the unconformity. It represents a period of missing geological time in the rock record.
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.
Which of the following best characterizes an angular unconformity?
An angular unconformity is a type of unconformity where older layers of rock are tilted or folded before younger sedimentary layers are deposited on top. This results in a clear angular discordance between the two sets of rock layers, showing a gap in the geologic record.
Beds one on top of each other as a word?
Bunk beds
What is the angular unconformity?
Tilted strata lie below the unconformity; bedding in younger strata above is parallel to the unconformity.
What are beds on top of each other called?
Beds stacked on top of each other are typically referred to as bunk beds. Bunk beds are commonly used in situations where space is limited, such as in children's bedrooms or dormitories. The top bunk is accessed by a ladder or stairs, and safety rails are usually installed to prevent falls.
Where is beds?
In the museum.(the top floor)
Which unconformity has layers that are perpendicular to each other?
Angular unconformity :D
Who were martin frobisher's siblings?
Martin Frobisher had two siblings: a brother named John Frobisher and a sister named Joan Frobisher.
What name is given to layers of tilted rocks that are overlain by younger more flat lying rock layers?
angular unconformity
How does an unconformity formed?
1) Deposition of sediment 2) Rocks are uplifted and eroded 3) Erosion of strata 4) New rock is laid down on top of older rock 5) Uplift and erosion exposes the unconformity at the surface
