What is the difference between conformable and unconformable strata?
Wiki User
∙ 13y ago
When layers of rocks are deposited in a continuous succession through time without any significant break in deposition they are conformable. But if deposition is interrupted or there is an episode of erosion between deposition then the boundary between the older and younger rocks is unconformable, in essence part of the geologic record is missing.

What fundamental concept states that in a horizontal sequence of conformable sedimentary strata each higher bed is younger than the bed below it?
law of superposition
Are laccoliths an example of intrusive igneous activity?
Yes they are. Laccoliths can lift the sedementary strata they penetrate. Laccoliths are igneous rock forcibly injected between sedimentary strata.
When did Strata Marcella end?
Strata Marcella ended in 1536.
What are Strata Management Services?
Strata management services are the professional services provided by strata managers to the owners corporations of strata schemes. The services provided by strata managers include the administration and management of the common property, the preparation and circulation of meeting agendas and minutes, the collection and payment of strata levies, the coordination of maintenance and repairs, and the provision of advice to owners corporations on a range of strata-related matters.
An unconformity is a buried?
A surface between successive strata representing a missing interval in the geologic record of time, and produced either by an interruption in deposition or by the erosion of depositionally continuous strata followed by renewed deposition.
What is the difference between strata and blocks in statistics?
Blocking is more for experimental design while strata is for survey sampling.
What is the difference between strata and stratification?
Stratification is the process by sedimentary rocks are arranged in layers. Strata is just the layers of rock
What fundamental concept states that in a horizontal sequence of conformable sedimentary strata each higher bed is younger than the bed below it?
law of superposition
What is Walthers Law of Correlation?
Facies that occur that occur in conformable vertical successions of strata also occur in laterally adjacent environments. (Johannes Walther, 1894)
What is a rock unconformity?
a break in a sedimentary sequence that does not involves a difference of inclination between the strata on each side of the break
What is the difference between a simple random sample and a stratified random sample?
Sometimes a population consists of a number of subsets (strata) such that members within any particular strata are alike while difference between strata are more than simply random variations. In such a case, the population can be split up into strata. Then a stratified random sample consists of simple random samples, with the same sampling proportion, taken within each stratum.
Where is the Paleozoic strata?
The Paleozoic era occurred between 570 and 230 million years ago. The Paleozoic strata can be found below the Mesozoic strata and is characterized by the appearance of marine invertebrates and primitive reptiles.
When was Strata - Strata album - created?
Strata - Strata album - was created on 2004-07-27.
Which kind of uncomformity has an erosional surface between parallel strata?
disconformity
Are laccoliths an example of intrusive igneous activity?
Yes they are. Laccoliths can lift the sedementary strata they penetrate. Laccoliths are igneous rock forcibly injected between sedimentary strata.
What is the definition of bedding plane in geological view?
A bedding plane is the area of separation between rock strata made by a cyclical or situational deposition of sediment. Bedding planes are originally parallel to the horizon, but the strata inclination can be altered by crust moving events.
What is the difference between antiform and anticline?
anticline is a convex up fold with the oldest bed at the core, whereas antiform is the descriptive term used for any convex up fold. antiform should be used when the age relationship between the strata are unknown.
