Septarians were formed during the Cretaceous period, 50 to
70 million years ago when the Gulf of Mexico reached what is now Southern
Utah. Decomposing sea life killed by volcanic eruptions, had a chemical
attraction for the sediment around them, forming mud balls. as the ocean
receded, the balls were left to dry and crack. Because of their bentonite
content they also shrank at the same time trapping the cracks inside. As
decomposed calcite from the shells was carried down into the cracks in the
mud balls, calcite crystals formed. A thin wall of calcite was
transformed into aragonite separating the bentonite heavy clay exteriors
from the calcite centers. Because of this, the nodules are called
Septarians. Septarians are composed of Calcite (The Yellow Centers),
Aragonite (The Brown Lines) and the Outer Grey Rock is Limestone.
Occasionally the fossil or some of the fossils which started the formation
of the rock is noticeable in the rock.

Quartz is the second most common mineral in the Earth's continental crust.
It is mainly composed of Silica or Silica based minerals. Although Quartz
is known by a variety of names, the most important distinction between types
of Quartz is that of macro-crystalline, individual crystals visible to the
unaided eye, and micro-crystalline, where aggregates of crystals are only
visible under high magnification. There are many forms of Quartz including
Chalcedony, Amethyst, Citrine, and Carnelian which are results of mineral
impurities or heat treatments.

Aventurine is a form of Quartz that is characterized by its translucent
and mineral inclusions that give it a shimmering or glistening effect
called "aventurescence". The most common color is green but it may also
be orange, brown, yellow, blue or grey. |

Agates mostly occur as nodules in volcanic rocks or waters containing
silica in solution possibly derived from the decomposition of silicates in
the lava. The siliceous matter is deposited in regular layers resulting
in the banded or striped formation.

Onyx is a banded variety of Calcite. The colors of
its bands range from white to almost every color except shades of purple,
blue and black. It is used for vases, bowls, beads, cabochons and
other items. This type is found in Mexico and Pakistan and is often
carved and polished into various items. This material is much more
readily available and softer than the gemstone commonly called Black Onyx
which is a silica gem.

Calcite is a Carbonate mineral that is most widely distributed on
the Earth's surface. It is a common constituent of sedimentary rocks with
Limestone in particular. A Calcite formation can take on many different
shapes and sizes which is dependent on the location, ground water
occurrence and temperature. Calcite is usually white or colorless but can
be gray, red, yellow, green, blue, violet, brown or black. The deeper the
color is usually indicative of the definitive impurities from the earth or
water.

SP909b Here is a very pretty sphere carved from Jet. This
sphere measures approximately 2 1/8" in diameter and has a good polish. A
very nice piece. Jet is a geological material and is considered
to be a minor gemstone. Jet is not considered to be a true mineral, but
rather a mineraloid as it has an organic origin, being derived from
decaying wood under extreme pressure. Jet is either black or dark brown
and may contain pyrite inclusion which give a brassy color and metallic
luster.

Indigo Gabbro or Mystic Merlinite is a newly mined crystal from
Madagascar. It has amazing colors from light indigo purple to black.
Gabbro refers to a large group of dark, coarse-grained, intrusive mafic
igneous rock chemically equivalent to Basalt. The vast majority of the
Earth's surface is underlain by Gabbro within the oceanic crust, produced
by Basalt magmatism at mid-ocean ridges. Gabbro often contains valuable
amounts of Chromium, Nickel, Cobalt, Gold, Silver, Platinum and Copper
Sulfides. The name given to Merlinite is by no means a random act. It's source in Cornwall, England
has long been associated with the legend of King Arthur and his sorcerer
Merlin.

Petrified Wood is a type of a fossil as it consists of fossil wood
where all the organic materials have been replaced with minerals while
retaining the original structure of the wood. These minerals are most
often Silicates such as Quartz. Other minerals, Manganese, Iron and
Copper, in the water or mud during the petrification process gives
Petrified Wood a variety of color ranges: black - Carbon; green/blue -
Copper; red/brown/yellow - Iron. Petrified Wood can preserve the original
structure of the wood in all its detail all the way down to the
microscopic level. Structures such as tree rings and the various tissues
are often observed features. Although Petrified Wood can be found
worldwide, it is rather rare in larger quantities and at times can be
difficult to obtain by the average collector.

Stromatolites are one of the oldest bacterial microfossils known. The
Peruvian Stromatolites are from the lower Proterozic period some 2.3
billion years. They are from the Eastern Andes, Bolivia, South America.
Stromatolites are actually mounds of mud that have been preserved. Very
few will actually contain the fossilized microbes that built them. They
accumulate because blue- green algae produces a sticky film that catches
mud and silt, in turn forming layers. In time theses layer build up to
form mounds. |

Marble is a metamorphic rock consisting of Limestone but composed
mostly of Calcite. It is used extensively for sculpture, building
materials and has many decorative uses. The pure white Marble is probably
the most common form known, but the characteristic swirls and veins of
many colored Marble varieties are usually due to various mineral
impurities such as Clay, Silt, Sand, Iron Oxides or Chert. |

Dumortierite is a fibrous variably colored aluminum boro-silicate
mineral. Dumortierite crystallizes typically forming fibrous aggregates of
slender prismatic crystals. The crystals vary in color from brown, blue
and green to the more more rare violet and pink. Dumortierite Quartz is
blue colored Quartz containing abundant Dumortierite inclusions.
Dumortierite was first describes in 1881 in the Rhone Alps of France and
was named for the French Paleontologist Eugene Dumortier. Dumortierite is
sometimes mistaken for Sodalite and has been used as an imitation for
Lapis Lazuli. Dumortierite can be found in Austria, Brazil, Canada,
France, Italy, Madagascar, Namibia, Nevada, Norway, Poland, Russia and Sri
Lanka. |
