TitleHematite and jasper from Michigan
DescriptionHematite Fe2O3 (iron oxide), is a very important ore of iron. Jasper, a type of quartz, is an opaque variety of chalcedony occurring in all colors. It is sometimes impure, containing organic material and iron oxides. Some jasper is banded, and these banded jaspers are also agates. When jasper does not exhibit interesting colors or patterns, it is known as chert.
