AGATE
Where Agate is Found
Nova Scotia.
How Agate is Formed
Agate is a banded mineral that occurs in an infinite amount of colours and
patterns. No two agates are alike.
Common Uses of Agate
The extraordinary beauty and uniqueness of agate makes it very popular.
Used as a semiprecious gemstone. Because of its hardness and ability to
resist acids, agate is used to make mortars and pestles to crush and mix
chemicals.
Name of mineral

AMETHYST
Where Amethyst is Found
Nova Scotia.
How Amethyst is Formed
Amethyst is a violet or purple variety of quartz. Traditionally included as
among the most valuable gemstones (along with diamond, sapphire, ruby,
and emerald), amethyst lost much of its value because of the discovery of
huge deposits in locations such as Brazil.
Common Uses of Amethyst
Amethyst was used as a gemstone by the ancient Egyptians. Fine, clear
specimens are suitable for cutting as ornamental stones.
Name of mineral

ANALCITE
Where Analcite is Found
Nova Scotia.
How Analcite is Formed
A white or light-colored mineral, a form of zeolite composed of hydrated
silicate of sodium and aluminum and found in crystal form in igneous rock.
Common Uses of Analcite
Used in ceramics.
Name of mineral

APOPHYLLITE
Where Apophyllite is Found
Nova Scotia.
How Apophyllite is Formed
The name refers to a specific group of minerals found in ancient lava and
basalt flows. The crystals grow in the now solid cavities formed by air
bubbles when the rock was molten.
Common Uses of Apophyllite
Apophyllite is used almost exclusively as collector's mineral, and is popular
because of its abundance, color variety, and well-defined crystals.
Name of mineral

BLADED STILBITE
Where Bladed Stilbite is Found
Nova Scotia.
How Bladed Stilbite is Formed
Zeolites are a large group of minerals named because of how they swell
and bubble under high temperature. They are usually found in veins and
cavities of igneous rocks, especially basalt. Among the more common
zeolites are stilbite, chabazite, natrolite, and analcite.
Common Uses of Bladed Stilbite
Zeolites are used as water-softening agents.
Name of mineral

CALCITE
Where Calcite is Found
Nova Scotia.
How Calcite is Formed
Calcite is the primary ore of calcium. It is one of the most widely distributed
minerals on the Earth's surface.
Common Uses of Calcite
An important building material, forming the base of cement. It is also crucial
in the manufacture of fertilizers, metals, glass, rubber, and paint. Calcite is
also the main component of chalk, which is processed as drawing chalk.
Name of mineral

CHABAZITE
Where Chabazite is Found
Nova Scotia.
How Chabazite Schist is Formed
Chabazite is found in cavities in igneous rocks and as a deposit in hot
springs. It forms in the petrified bubbles (called vesicles) of volcanic rocks
that have had a slight amount of metamorphism; it is a hydrated silicate of
calcium and aluminum.
Common Uses of Chabazite
Used commercially in electrochemical processes. It is used to remove
cesium-137 and strontium-90 from out-flowing radioactive sewage, also
used to remove ammonia, silver, copper or cobalt from solutions.
Name of mineral

CHALCEDONY
Where Chalcedony is Found
Nova Scotia.
How Chalcedony is Formed
Latin from Greek khalkēdōn, “a mystical stone.” A translucent or grayish
form of quartz in which the microscopic crystals are packed together in
parallel bands.
Common Uses of Chalcedony
Used as a gemstone and in ornaments.
Name of mineral

DOLOMITE
Where Dolomite is Found
Nova Scotia.
How Dolomite is Formed
This is the name of both a sedimentary rock and a mineral found in crystals.
Common Uses of Dolomite
Dolomite is used as an ornamental stone, as a raw material for the
manufacture of cement, and as a source of magnesium oxide. It is an
important petroleum reservoir rock. Sometimes added to soils to lower their
acidity.
Name of mineral

GYPSUM (var. Alabaster)
Where Gypsum (var. Alabaster) is Found
Nova Scotia.
How Gypsum (var. Alabaster) is Formed
Gypsum is formed from the evaporation of salt water.
Common Uses of Gypsum (var. Alabaster)
One of the most common building materials in the world. It is used for
interior prefabricated drywall. Other uses for include dental plaster,
modelling casts, moulds, surgical casts, drilling mud, used in cement, as a
filler in paints, gesso, in the smelting of nickel, and in the manufacture of
crayons, chalk, and toothpaste, in the production of tofu, to improve the
mineral content of water. Gypsum is the main ingredient of plaster of Paris
and it is used to make cement, drywall, and fertilizer.
Name of mineral

GYPSUM (var. Satin Spar)
Where Gypsum (var. Satin Spar) is Found
Nova Scotia.
How Gypsum (var. Satin Spar) is Formed
See Gypsum (var. Alabaster)
Common Uses of Gypsum (var. Satin Spar)
See Gypsum (var. Alabaster)
Name of mineral

HEULANDITE
Where Heulandite is Found
Nova Scotia.
How Heulandite is Formed
Heulandite is one of the most common members of the Zeolite Group. It can
have a nice pearly lustre and lovely colours. It forms complex and unique
crystals and is often seen with other rare and beautiful minerals. Heulandite
forms large crystals in the petrified bubbles of volcanic rocks that have slight
metamorphism.
Common Uses of Heulandite
Used a chemical filter, chemical absorber, and water purifier.
Name of mineral

JASPER
Where Jasper is Found
Nova Scotia.
How Jasper is Formed
An impure form of chalcedony, usually coloured red by iron impurities.
Common Uses of Jasper
Used as a gemstone in jewellery and ornaments.
Name of mineral

MAGNETITE
Where Magnetite is Found
Nova Scotia.
How Magnetite is Formed
A common black magnetic mineral consisting of iron oxide, it is the only
mineral that works like a magnet. Although its magnetism is weak, it is
strong enough to attract large nails. Due to its magnetic properties, very fine
iron filings cling to its surface.
Common Uses of Magnetite
It is an important ore of iron.
Name of mineral

NATROLITE
Where Natrolite is Found
Nova Scotia.
How Natrolite is Formed
From French, Spanish and Arabic natrūn from Greek nitron (see niter). A
light-colored mineral (white, yellow, or gray) consisting of hydrous sodium
carbonate, found in saline (containing salt) residues.
Common Uses of Natrolite
Once used in embalming. Niter is a white crystalline salt used in curing
meat, in rocket propellants, as a fertilizer, and in making explosives, pottery,
and glass.
Name of mineral

QUARTZ
Where Quartz is Found
Nova Scotia.
How Quartz is Formed
Quartz is one of the most common minerals found in the Earth's continental
crust. It is the main ingredient in sand, sandstone, and granite. A large
portion of the dust in the air is quartz. Quartz grows as a single crystal or in
masses. In rare instances, a single quartz crystal can grow to be very large.
Common Uses of Quartz
As a crystal, it is a semiprecious gemstone. Varieties include amethyst, rose
quartz, and smoky quartz. Used in optical devices (prisms, lenses) and
electrical components. Used in the manufacture of glass, paints, and
abrasives.
Name of mineral

SILICEOUS SINTER
Where Siliceous Sinter is Found
Nova Scotia.
How Siliceous Sinter is Formed
A whitish mineral sediment consisting of porous silica or calcium carbonate
deposited by a mineral spring.
Common Uses of Siliceous Sinter
No information found.
Name of mineral

TABULAR STILBITE
Where Tabular Stilbite is Found
Nova Scotia.
How Tabular Stilbite is Formed
From Greek stilbein “to glitter,” because of its lustrous crystals. A white or
yellow mineral consisting of a silicate of aluminum, calcium, and sodium
chemically combined with water.
Common Uses of Tabular Stilbite
Used in petroleum refining.
