Perhaps you should try some spelling variations:
sedimentary structures » secondary structures
structures analysis » structure analysis, structural analysis, structural analyses
lake sedimentary » life sedimentary, scale sedimentary, lake sediments

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: (( lake sedimentary structures analysis ) OR ( line ((segment based) OR (fragment based)) analysis )).
• Adding a wildcard symbol may retrieve word variants: (( lake sedimentary structures analysis ) or ( line ((segment based) or (fragment based)) analysis ))*.
