Stratigraphic position Age Dating techniques i.e. carbon etc Fossil Assemblage present in rock specimen
The layers of any sedimentary rock are called strata.
The law of superstition, also known as the law of superposition, states that in undisturbed sedimentary rock layers, older layers are found below younger layers. This principle helps paleontologists date fossils by examining their positions within these layers. If a fossil is found in a lower layer, it is considered older than fossils found in higher layers. Thus, the relative age of fossils can be determined based on their stratigraphic context.
The number of years represented between the deposition of the bottom and top layers can be estimated by determining the age difference between the two layers. This can be done through various dating techniques like radiometric dating or stratigraphic analysis. The exact number of years would depend on the specific context and location of the layers.
To determine which numbered rock layers are younger than the igneous intrusion layer, you would need to refer to a specific geological cross-section or diagram. Generally, in geology, igneous intrusions are younger than the surrounding sedimentary layers because they form after the existing layers have been deposited. Therefore, any rock layers that are located above the igneous intrusion in the stratigraphic sequence would be considered younger.
The boundary between two sedimentary rock layers is called a bedding plane or stratigraphic boundary. It represents a break in the deposition of sediment, marking a change in the environment or conditions under which the rocks were formed.
Hydrocarbon traps that form in geologic structures such as folds and faults are called structural traps. Hydrocarbon traps that result from changes in rock type or pinch-outs, unconformities, or other sedimentary features such as reefs or buildups are called stratigraphic traps.

To read a stratigraphic map, start by understanding the layers of rock formations represented by different colors or symbols. Identify the key indicating the age and type of each layer. Pay attention to the structure symbols like strike and dip to understand the arrangement of layers. Study the cross-sections provided to visualize the subsurface geology in three dimensions.
The dating method you are referring to is called the Law of Superposition. It states that in an undisturbed sequence of rock layers, the youngest rocks are at the top and the oldest are at the bottom.
2 layers but up to 20 layers are expected in the near future
the principle of superposition, which states that in an undisturbed sequence of rock layers, the youngest layer is on top and the oldest is on the bottom. This principle helps geologists determine the relative ages of rock layers based on their position in a stratigraphic sequence.
The process is called correlation, where geologists match rock layers in different regions based on similar characteristics, such as rock type, age, and fossils present. This helps in understanding the geological history and past environments of a larger area.
