Characteristics of Sedimentary Rocks -
by Dr. Michael Pidwirny, University of British Columbia Okanagan
The properties of sedimentary rocks are introduced in this illustrated section from an online textbook (Fundamentals of Physical Geography, Michael Pidwirny, University of British Columbia Okanagan, Canada). Key terms are linked to definitions in an accompanying glossary.

Classifying Sedimentary Rocks
Sedimentary rocks, by Pamela Gore, Georgia Perimeter College
Part of a physical geology course, these notes provide a brief, illustrated introduction to sedimentary rocks, covering terrigenous sedimentary rocks (also called detrital or clastic), chemical/biochemical sedimentary rocks (including the evaporites, the carbonates and the siliceous rocks), organic sedimentary rocks, and other types.
"Sedimentary
Rocks " - USGS
This site explains the classification of sedimentary rocks based
on their quartz, feldspar and lithic composition.

Sedimentary Rocks,
by Dr Mary Lou Bevier, University of British Columbia
This online guide to sedimentary rocks was complied by Dr Mary Lou Bevier for a course in petrology at the University of British Columbia. It provides an overview of both carbonate and siliclastic rocks including information on petrography, provenance, depositional environment, diagenesis and chemistry. There are many diagrams and some photographs. It also contains exercises and links to other sites. Certain parts of the site are under construction and certain areas are available only to students of the University of British Columbia.
