POSTMODERN PETROLOGY FOR POETS

THE NEW YORK REVIEW 
OF POSTMODERN GEOLOGY
Deconstructing the un-natural history of the anthropocene epoch since 2006
Will the Anthropocene be the first era since the Cretaceous-Tertiary Extinction in which all rocks get to be famous for 15 minutes?

This brave new epoch has already seen the TV debut of a prime-time worthy gypsum deposit that puts Industrial Light & Magic's best CGI to shame.

The crystal cave's high Nielsen rating created a gold rush of producers seeking out-of-this-world terrestrial geology to televise, and the few geology libraries to survive the Holocene-Anthropocene Extinction have thronged by science writers seeking news of  postmodern rock discoveries, including

Trinitite
The earliest dated rock of the Postmodern epoch is a green-violet, obsidian-like fused lithic 
The holotype,  a thin stratum of  un-natural glass emplaced in the White Sands of New Mexico. has a tritium age of 6.9 milli-eons, slightly older than deposits of the Terminal Showa formation that outcrop in Japan's Hiroshima and Nagasaki prefectures, and varous remote locales   in Nevada, Kazakhstan, China's Lop Nor basin . Highly enriched in transuranic elements, trinitite specimens look far older than their years.

Tellerite 
An ephemeral variety of trinitite that resembles popcorn while it lasts,  results from the abrupt explosion of calcium carbonate  into porous burnt lime when hydrogen bombs  explode over coral.

 

It was briefly reported on some now vanished Pacific coral atolls, but all the holotype material  turned to lime water in the first tropical shower following its discovery
Macadamite
While most sedimentary strata  form thick horizontal sheets, hydrocarbon rich macadamite occurs only as thin two dimensional ribbons  containing unfossilized flattened faunal remains
Interwoven veins of macadamite of astonishing extent and complexity have been mapped in Southern California, and form a beltway connecting the Cretaceous formations of Maryland & Massachusetts.

Saddamite   
More mafic than Maccadamite, this high-temperature no-pressure  lithic facies results from extreme local  heating of holocene tar sands in  regions prone to  pyromania, including Iraq and Kuwait.
Saddamite consists of  sand grains in a matrix of carbon black and pyrolized asphaltenes, a petrogenesis  that defies  natural explanation.  While high nickel and vanadium porphyrin levels suggest an  origin in marine cretaceous petroleum, the infernal thermal fluxes needed to generate pure carbon in such amounts only result from the deliberate ignition of oil fields 
Cryabase
The new discipline of meteopetrology focuses on cryabase, the only terrestrial rock consisting enirely of condensed air.  

Its minerals include native oxygen and nitrogen,  ice  I & IVcrystals , priestlyite (the carbon analog of silica) ,and  minute crystallites of argon, , neon, krypton and Freon.
The  sporadic type locality at Cape Canaveral  transiently features aircicles and flowstone like crusts on  liquid hydrogen tanks, where cryabase  avalanches can cause self-inflicted meteor damage to Space Shuttles.

While rare outside the Kuiper Belt, cryabase may become depressingly common in the inner solar system if Senator Inhofe's views on global warming  are correct.


Caution should be exercised in collecting cryabase samples, as geologists' picks tend to embrittle severely at frozen air temperatures, and the temptation to lick field samples for a better view of microstructure can lead to severe frostbite of the tongue.
Saganite
A phenomenally cold and dark family of aerosol minerals arbitrarily small amounts  of which can reportedly lower global temperatures below freezing for 40 days and 40 nights. The  type report published in Science in 1983 seems largely based on the related species, apocryphite, found in many factoid deposits, but lacking the consciousness raising properties of the material originally published . 
Saganite exemplifies the  unstable  minerals grouped as the "factoidite"  melange  arising from hermeneutic metamorphism during high-pressure  deformation professionel  

Little is known of its physical properties as despite its extensive literature , it only occurs in nuclear winters.  Saganite may be  semiotically related to the War of the Worlds symplectite, first reported from Grovers Mills New Jersey by Orson Welles in 1938.

The Tora Bora Metapeltites
Some anthopocene cave deposits in the Hindu Kush and Waziristan syntaxis show signs of shock and awe  deformation. Their extensive contamination with shards  of lead and depleted uranium frustrated   postmodern petrologists seeking to connect them to:
The Ground Zero Gneiss
Known only from deposits in lower Manhattan, this product of political catastophism is a mylonized migmatite containing portlandite,  asbestos fibers, enormous laths and corrugated sheets of metallic iron and  mica-like sheets of carbonized cellulose with angular markings more legible than graphic granites, many pertaining to world trade.
