The Sedimentary Zone


This page is intended to give you some of the fundamentals of what comprises
a sedimentary deposit in theory and then to show you some of the unique minerals from the
collecting site links found herein. The collecting sites are described as well.


    • What is a sedimentary deposit?
    • A sedimentary deposit one that has rocks formed at or near the surface of the earth. Most of these deposits are formed over long spans of time from the gradual deposition of sediments as a result of weathering, wind and water. They are usually deposited in beds or layers and nearly all are composed of shale, sandstone and limestone. By volume sedimentary rocks comprise only 5% of the crust but cover 75% of the earth's surface.
