Perhaps you should try some spelling variations:
rafted sediment » grained sediment, related sediment, treated sediment
dated sediment » dated sediments, water sediment, related sediment
1e decrease » 14 decrease, 1d decrease, 2e decrease
13 decrease » 14 decrease, 1d decrease, 3 decrease

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: ((1e decrease) OR (13 decrease)) ((rafted sediment) OR (dated sediment))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((1e decrease) OR (13 decrease)) ((rafted sediment) or (dated sediment))*".
