Museum Specimens

Hematite is an iron oxide mineral. Most iron ore deposits consist mainly of hematite, magnetite, or both.
Hematite gets its name from the Greek word for blood (haimo) because of the color of its powder and the red
streak it leaves when scratched across a piece of unglazed porcelain. Hematite is black, but when powdered
or fragmented can show colors ranging from ochre red to jet black. Hematite crystals are a silvery, shiny
opaque gemstone that almost looks like metal. Hematite specimens are normally an opaque mineral with a
dull luster and it is also known as "black diamond". Historically it was used in the making and coloration of
pottery. It was also made into a paste from which beads were made and hardened, and appears commonly
today as black beads in costume jewelry. Hematite is an iron ore that is very popular in bead and jewelry
designs. Nearly all Hematite beads on the market are manmade materials.

Hematite and magnetite concretions or nodules, sometimes called ironstone concretions, are often mistaken
for meteorites because their unusual shapes catch people's attention and they are denser than most other
rocks. Hematite concretions are formed in sedimentary rocks by oxidation of pyrite or marcasite (iron sulfide)
crystals or precipitation of iron oxide from iron rich solutions. Concretions come in a wide variety of unusual
shapes. Sometimes they're shiny on the surface, which might give the impression of a meteorite fusion crust.

While the forms of hematite vary, they all have a rust-red streak. Hematite is harder than pure iron, but much
more brittle. Huge deposits of hematite are found in banded iron formations. Grey hematite is typically found
in places where there has been standing water or mineral hot springs, such as those in Yellowstone. The
mineral can precipitate out of water and collect in layers at the bottom of a lake, spring, or other standing
water. But hematite can also occur without water, as the result of volcanic activity.

Hematite appears in many forms in nature, such as Kidney Ore, a bumpy ore that has an appearance likened
to a kidney; Hematite Rose, a formation with crystals in the shape of petals; Tiger Iron, a sedimentary rock
with Hematite mixed into its multiple layers; Oolitic, sedimentary deposits of small, circular Hematite grains;
and Micaceous Hematite, a scaly, shiny stone valued for decorative uses. Its soft Earthy, form is called Red
Ochre. Hematite often appears within other crystals such as Aventurine or as phantom crystals.
Hematite on Mars
Hematite has even been detected on Mars. In 1998 the Mars Global Surveyor (MGS) spacecraft found a large
deposit of hematite near the equator of Mars. "We believe that the gray hematite is very strong evidence that
water was once present in that area," said Victoria Hamilton, a planetary geologist at Arizona State University
(ASU). She went on to say, "we think the deposit is fairly old. It was buried, perhaps, for several hundred
million years or more and now it's being exposed by wind erosion. Water is essential to life as we know it and
this finding bolsters the theory that life may have existed on Mars".
