Disconformity
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.
If the age of a certain rock strata is found by the use of isotopic methods and another nearby strata is found to contain trilobite fossils, assuming there is no unconformity between the two strata we can infer the approximate age of the trilobites within certain parameters.
a break in a sedimentary sequence that does not involves a difference of inclination between the strata on each side of the break
An unconformity is formed when sedimentation ceases for a period, leading to erosion or non-deposition, and then resumes later. This gap in the geological record represents a significant time during which environmental conditions changed, allowing for the effects of wind and water to alter the landscape. As new sediments are deposited on top of the eroded or missing layers, the unconformity becomes evident in the rock strata. This process highlights the dynamic nature of Earth's surface and the ongoing interaction between sedimentation and erosion.
Strata.
Tilted strata lie below the unconformity; bedding in younger strata above is parallel to the unconformity.
Angular unconformity is a type of unconformity in which tilted or folded rock layers are overlain by horizontal rock layers. This indicates a period of deformation and erosion followed by deposition of younger sedimentary layers. It represents a gap in the geologic record.
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.
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.
An angular unconformity, which is what I think you mean, is not a rock type. It denotes the junction of two strata of rocks where the lower one was tilted by tectonic forces, eroded, then overlain with horizontal parallel strata.
Type your answer an unconformity indicates where a layer is missing in the strata sequence, so it tells you that there is a missing rock layerhere...
angular unconformity
A disconformity exists between parallel layers of sedimentary rock. This is when there is a gap in the rock record represented by a horizontal surface separating younger strata from the older ones.
both are true
Want of conformity; incongruity; inconsistency., Want of parallelism between strata in contact.
Unconformity: a gap in the geological record where rocks are missing due to erosion or non-deposition. Disconformity: a type of unconformity where the contact between strata represents a period of erosion or non-deposition. Nonconformity: an unconformity where sedimentary rocks overlay igneous or metamorphic rocks.
