If it differs how do you explain the differences. You will need to take this error into account when you determine the depositional environment for you sample. Compare your sample analyzed with the known depositional environment samples as to angularity of sediment grains and the percentage of dark and light colored minerals. Briefly comment on this comparison. If it differs how do you explain the differences.
Conclusions are a very important part of science.
Conclusions are constructed by interpreting the data you have produced. This exercise synthesizes what we have learned thus far in lab. Weathering, Sedimentary Rocks, Depositional Environments, Relative dating all come into play in producing these conclusions. Depending on the samples given, you may have an historical picture of the changes of environment for a specific locality.
