    Iron-rich sedimentary rocks are sedimentary rocks which contain 15% or more iron.However, most sedimentary rocks contain iron in varying degrees. The majority of these rocks were deposited during specific geologic time periods: The Precambrian (3800 to 570 million years ago), the early Paleozoic (570 to 410 million years ago), and the middle to late Mesozoic (205 to 66 million years ago).

  • Everything You Need to Know About Sandstone

    Aug 14, 2019· Sandstone, simply put, is sand cemented together into rock — this is easy to tell just by looking closely at a specimen. But beyond that simple definition lies an interesting makeup of sediment, matrix, and cement that can (with investigation) reveal a great deal of valuable geologic information.

    Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) silicate grains. Sandstones make up about 20 to 25 percent of all sedimentary rocks. Most sandstone is composed of quartz or feldspar (both silicates) because they are the most resistant minerals to weathering processes at the Earth's surface, as seen in the Goldich dissolution series.
