Sedimentary rock Ironrich sedimentary rocks Britannica

Sedimentary rock Sedimentary rock Ironrich sedimentary rocks: Almost all sedimentary rocks are ironbearing in the sense that mudrocks sandstones and carbonates typically have an iron content of several percent. Nevertheless sedimentary rocks in which the proportion of iron exceeds 15 percent are separately egorized as ironrich.

The Chemical Composition of Lunar Soil Some Meteorite

On Earth iron exists in the 2 ferrous and 3 ferric oxidation states so in chemical analysis of rocks Fe concentrations are usually stated as Fe 2 O 3 because the ferric oxidation state is more common than ferrous oxidation state. On the Moon there is effectively no oxygenbearing atmosphere so there are no iron 3 iron minerals.

Meteorite Identifi ion Public Clemson University South

A majority of meteorites contain a significant amount of iron. If it isnt magnetic it probably isnt a meteorite. 6 7 Are meteorites heavy Typically yes. The same thing that causes meteorites to be magnetic often causes them to be heavy: their high iron content. This iron causes them to be more dense than earth rocks of the same size
