Iron-rich sedimentary rocks - Wikipedia

Dec 16, 2010  Iron-rich sedimentary rocks are sedimentary rocks which contain 15 wt.% 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

Interpreting Water Tests for Ponds and Lakes

Aug 27, 2015  Hardness is a measure of calcium and magnesium concentration in water and is controlled by the source of the pond water. Ponds in limestone areas will generally have harder water than those in areas underlain by sandstone or shale. The hardness of pond water is usually unimportant except when using some aquatic herbicides.

Iron and manganese are detected at relatively high concentrations in the Wasatch aquifer and coalbed aquifers, often at concentrations greater than regulatory standards (Martin and others, 1988; Rice and others, 2000). Both iron and manganese are highly sensitive to redox conditions and both are more soluble in reducing conditions (Hem, 1985).
