Its position in the stratigraphic column, particularly if there are any index fossils.
if that fails, then radiometric dating techniques may be appropriate. There are a wide variety of radioisotopes to be used ranging from 14C (5700 years half life) through K-Ar, and to the various uranium series.
That would be relative dating / chronostratigraphy.
I believe that the answer you are looking for would be relative dating.
relative dating
It is called "relative" dating.
correlation
The different bands in sedimentary formations are called strata.
Strata.
The layers in sedimentary rocks are called strata.
sedimentary rocks
Strata refers to the individual layers in sedimentary rock. On occassion, igneous rock can also demonstrate stratification.
The investigative process by which geologists identify and match sedimentary strata and other rocks of the same ages in different areas is referred to as correlation.
The process by which layers of sedimentary rock are formed is called strata.
Strata refers to distinct layers or divisions within a rock formation or other material. Stratification refers to the process of arranging or forming these layers. In essence, strata are the actual layers, while stratification is the process of layering.
The different bands in sedimentary formations are called strata.
Sedimentary Rock. Strata is layers of sedimentary rock that form from the deposition of sediment.
Strata.

That process, of itself, does not form a particular "type" of rock. what it produces is rock "strata" where the rock involved could be igneous or sedimentary in origin.
