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).ron-rich sedimentary rocks are sedimentary rocks which contain 15% or more iron.
* A surfactant. * Also known as Sodium Lauryl Phenyl Sulfonate. Functions: Sodium Dodecylbenzenesulfonate is comprised of substituted aromatic compounds and used as a surfactant in a variety of cosmetics and personal care products, primarily cleansing products such as bath soaps and shampoos. It is considered a linear alkylbenzene sulfonate (LAS), or specific classification of surfactant that is known to be especially soluble and effective at low concentrations.
