A rare mineral. It is interesting primarily for its crystals, which, like a tiny treasure, found in a geode. Exclusive collector's mineral and other applications has not.
His name shall anapana Anapa - a city on the Taman peninsula (Russia), which was first discovered.
Appearance
Anapana ore occurs in the form of nodular aggregates, hidden in the clay and marly rocks associated with deposits of phosphates. It is from them anapana receives phosphorus required for the formation of molecules of the mineral. Often anapana crystallize inside the fossilized shells of bivalves and gastropods.
Single crystals and aggregates
The mineral is usually well-crystallized as in the case of single crystals, as well as in the case of spherulites (crystals radical located), has an irregular shape or form rosettes. Often there are parallel to the formation of small tabular or prismatic crystals. Larger units are dense intergrowths of crystals, which are difficult to separate the individual components. In addition, the crystal faces are curved, which gives it a kind of turret. Anapaita color varies from bright green to yellow-green, which is associated with the presence of iron ions in the mineral structure. There are also crystals of brown, but in this case, the change in color due to oxidation.

Handling Precautions
- Anapana, as well as other minerals that are in the structure of water molecules, requires careful handling. Aggressive treatment with overheating or the use of acids can irreversibly damage it.
- Mineral water should be washed with a low lime content (even better with distilled water) using a soft brush and neutral soap. It must be dried with a cloth, lint.
Association
Anapana met with a few minerals. Occasionally it is found together with vivianite and fayrfilditom who have similar origins. About anapaita species is not known.
Mineral or fossil?
Often it happens that anapana formed inside the fossilized shells of mainly Miocene time, creating a bizarre combination of fauna and minerals. The value of such instances in the eyes of collectors is much higher than just anapaita crystals.
Rare mineral
Town of Bellver de Cerdanya in the Pyrenees - one of the most famous deposits anapaita. Due to the small depth of the ore units with reniform anapaitom found here, even during farm work.
Anapana - one of many minerals belonging to the subclass of phosphates that do not have wide distribution. In the known deposits is present in large quantities.
From the Pyrenees to the shores of the Black Sea
Despite the small number of fields anapaita, the best of which are in Anapa (Russia), Kerch (Crimea peninsula, Ukraine) and in Bellver de Cerdanya (Lleida, Spain), it can be considered a common mineral. This is due largely to its sedimentary origin, the formation of a stable environment and conservation for a long time. In the Kerch and Anapa on the coast of the Black Sea, extracted brush anapaita crystals, whose color varies from light green to olive-green. Usually they are inside the fossilized shells of bivalve mollusks.
Did you know that ...
- Anapa is situated on a small peninsula of Taman. For this reason, the mineral was originally called "Tammany," which is now obsolete.
Where found anapana
The most beautiful specimens are obtained in the Crimea (Ukraine), because here they are formed within the fossils. For Spain (Bellver de Cerdanya, Lleida) is characterized by small crystals in the clay ore Kidney units associated with a certain type of plant fossils. In Europe anapana found in Santa Barbara and Tuscany (Italy), Messel (Germany). In addition, anapana mined in the United States - in Nevada, California and New Hampshire. swarovsky
