LONG LIVE SANDBOX

THIRD ITERATION

Item #: SCP-XXXX

Object Class: Euclid

Special Containment Procedures: All specimens affected by SCP-XXXX should be stored in cool, dry conditions with a relative humidity no higher than 30%. Suggested general instructions regarding cabinetry design, sterilization procedures, etc. can be found in Document xxxxxxx88 ("SCP Foundation General Collection Procedures Vol. 088: Integrated Pest Management"). Prolonged contact of any kind with SCP-XXXX is not permitted without prior authorization from the Level 3 supervisor on-site.

Currently, confirmed or suspected examples of SCP-XXXX are housed at Site-58, although special exceptions can be made given written clearance from senior staff members.

Description: SCP-XXXX is a phenomenon that affects fossils, superficially similar to the process of pyrite oxidation: when exposed to humidities greater than 45%, pyrite crystals within the fossils begin to gradually oxidize according to the following chemical reaction:

(4FeS2+ 13O2 + 2H2O) → (4FeSO4+ 2H2SO4+ 2SO2)

However, SCP-XXXX has never been observed to occur in inorganic mineral specimens. Permineralized, carbonized, and replacement fossil specimens are all potentially susceptible.

Special Containment Procedures: [Paragraphs explaining the Procedures] MTF Epsilon-8 ("Pet Shop Boys")

Description: SCP-XXXX is a pet store located in Pigeon Forge, Tennessee. While the exterior of the building is not anomalous, its interior is a spatial anomaly, measuring far greater in area than its external dimensions would permit. The exact internal dimensions of SCP-XXXX are so far unknown.

Commence informalness

So, it's like a pet store, but there's nobody staffing it. Items are paid for at a desk at the front of the shop. However, there is a card next to each item that has the payment options on it, and TBH it's quite complicated really I will figure it all out later

The further and further you explore this spatially anomalous pet shop, the items you find for sale get weirder and weirder - not just the animals (which are of types you would never sanely find in a pet store, btw), but the supplies as well. Fish food made from human remains, orthopedic beds designed for antelope, an ancient tome written in Latin regarding the care of salamanders (which I suppose isn't really anomalous but someone picked it up at a yard sale I guess), leashes for eels, etc.

Near the front there is a room different from all the others, labeled "Special Orders". Using an ATM-like feature, the shop can get you anything you want, to be delivered into the room next Thursday (Special Order day, y'see). Some special orders currently housed in the room include a Phillippine eagle and some golden toads (which is interesting since golden toads went extinct in the 80s). The Mock Turtle, however, is listed as being currently out of stock.

Also, the door locks automatically on Sundays.

Distance Anomalous Feature
XXXX ELEPHANT
XXXX BABY IGUANAS THAT JUMP AT THE MOON
XXXX A humpback whale, surrounded by a chain link fence. The whale shows no distress at being taken of water, despite its entirely aquatic lifestyle. Several copies of the 1969 King Crimson album In the Court of the Crimson King are displayed alongside it, apparently for sale.
4 kilometers? A darkened room of unknown dimensions, with a single spotlight shining down into its center. Contains an unusually large fish tank, occupied by a single arowana fish. Static can be heard from an unknown source.
A very very long distance in OMG it's a human, accompanied by a dromedary camel 50 cm at the shoulder. See Interview Log XXXX-1.

Marcasite and pyrite are two common minerals. Both FeS2 chemically, making them
polymorphs. Polymorphs are minerals with the same chemical composition but different crystal
structures. Diamond and graphite are polymorphs, both minerals being pure carbon. In diamond and
graphite the different arrangement of carbon atoms gives these two minerals of very different
physical properties. Pyrite and marcasite, on the other hand, have almost identical physical
properties, making them tough to tell from each other.

Let's go through their properties. Both are metallic and pale yellow to brassy yellow. Both can
tarnish and be iridescent. Both are 6-6.5 on the Mohs' hardness scale. Neither have a particularly
prominent cleavage, although marcasite does have one that occasionally shows up. Both have
densities of about 5 grams per cubic centimeter (pyrite is a bit denser, but not enough to be
detectible without delicate measurements). They can even be found together in the same rock.

Fortunately these minerals often show good outer crystal shapes that are quite different.
Pyrite crystals are generally equant, and dominated by cubes, octahedrons and 12-sided
pyritohedrons. Marcasite crystals are usually rectangular (tabular) with wedge-shaped ends and tend
to form in star shaped, radiating or cockscomb groups. Marcasite is also much more restricted in
occurrence than pyrite, forming only in low temperature, near surface, very acidic environments. It
is found in some ore deposits, in sediments formed under somewhat stagnant conditions and as
ground water precipitates in rocks such as in limestone and shale. Although pyrite can also be found
in many of these same environments, the crystal shapes are diagnostic. On a local note, small
marcasite and pyrite crystal groups occur in the dolostone bedrock up and down in the Mississippi
River in Wisconsin and Minnesota. These minerals, however, have been replaced by goethite (iron
hydroxide) so are brown, not bright and brassy.

Why do I say marcasite is "pyrite's evil twin"? First, jewelry sold as "marcasite" is really
polished pyrite. From a marketing sense, pyrite is often associated with the term "fool's gold" and
who wants jewelry made out of that? "Marcasite" sounds much more glitzy, even though it too is a
type of fool's gold. The second reason is marcasite's propensity to break down fast when exposed to
the air. Over time marcasite specimens, if unprotected (and sometimes even if protected) will break
down to a crumbling mass of white to yellow iron sulfates, leaving a stain on your shelf caused by
weak sulfuric acid. I've heard various explanations for this. It may be due to inorganic reactions
involving oxygen and moisture in the air. Some contend that marcasite is great food for certain
bacteria that metabolize the sulfide rapidly and cause its bveakdown. The marcasite from
Wisconsin's lead-zinc mining district is notorious for this. You can get a faint whiff of sulfur rich
fumes when you examine samples from this region. I was afraid to move a sample on display in the
Geology Museum at U.W. - Madison that I wanted photographed by Pete Rodewald (see photo
below) because I was sure it would crumble to a million pieces. This is one reason why specimens
from this region are not as widely collected as from, for example the Viburnum Trend or the Tristate
district of Oklahoma-Kansas and Missouri. Some pyrite is susceptible to this decay; in fact the
condition is sometimes referred to as "pyrite disease". On the other hand, some marcasite stays
stable in collections for decades. I personally wonder if a lot of stable "marcasite" may actually be
pyrite pseudomorphs (replacements).

I've tried several preservation modes. I've sprayed samples with clear Krylon, but they
sample's appearance is compromised and eventually the decay comes through so the samples just
fall apart slower. I've also tried soaking the samples in ammonia to neutralize the acid and kill off
bacteria, then rinsing and drying them thoroughly and keeping them in a very dry environment. On
the web you can read about other strategies, such as storing marcasite specimens permanently
immersed in water to keep out oxygen.

As for "marcasite" jewelry, you can see why you don't really want to wear true marcasite
beads! Your skin moisture would speed the decay process. The yellow powdery stains on your skin
would be definitely embarrassing, but the stings of sulfuric acid burns could be downright painful.

That said this is a somewhat intriguing idea and I might turn it into a regular SCP if I have the time and/or the inclination.
