In addition to the benefits that are used to find the relationship of the stones. Fossils have been used to accurately reflect the environment of the release of sediment accumulation. Although the accumulated environment may result from the study on the information from the stone floor.
Stone age fossil age, telling the age of fossil stone age? Can tell 2:
• age comparison (Relative Age) is the geological age of the rock fossils geological feature
?Or geological events, when compared with fossil rocks, geological characteristics, or other geological events, rather than indicating a number of years. Or another fossil. Based on where to place the stone sediments defines (the Index fossil) Mainly because stones each sludge must be used during the period of the call occurs. And must be based on the geological and technical (Stratigraphy) contains
.Study on comparison of time based on principles of truth. There are 3:
1. Rules for the rest of the nested layers generated (the Law of superposition). If a reversal is not generated by the natural phenomenon. The uppermost part of the stone age, this series will be minimal or mild, and the bottom is less than 2
age always, or. The rules of the Association to cut through rock layers (cross-cutting of Law relationship). The rock cut side stones passed into the younger stone is cut into
3. Comparison of the sedimentary rocks (correlation of sedimentary rock). A comparative study of the different sedimentary rocks in the area based on
g. Using physical characteristics based on the key bed (bed key). Where is the stone floor with its own specific features? ข. Compare with fossils (fossil by correlation). There is, in principle, any stone floor, if there is a common fossil or similar arising within it. The stone floor is the age or period of time occurs. A short period of time, but
