TIP BLACK STONES, THE SAMPLE OF FIRST EAGLE

 Di Primiano Aquilano: 

 LE PIRITI DI " PUNTA PIETRE NERE " SU MATRICE DI CALCARE NERO. 

   

  LA MATRICE VIENE CONFUSA DA  MOLTI PER BASALTO, MA UNA BANALE PROVA CON  HCL O  
  ANCHE  CON ACIDO MURIATICO EVIDENZIA LA CLASSICA  EFFERVESCENZA  DOVUTA ALLA  
 SCOMPOSIZIONE DEL CALCARE  CON EMISSIONE DI CO2. 
 LA ROCCIA  CALCAREA COSTITUIVA LA PARTE ALTA E DOMINANTE DELLA   SCOGLIERA  , COME  
 SI NOTA NELLA FOTO. DA CONSIDERAZIONI PERSONALI QUELLE ROCCE DOVREBBERO  
 RISALIRE  AL PALEOZOICO PERIODO PERMIANO, QUESTO SE C'E' UNA ANALOGIA , ED E'  
 PROBABILE , TRA LE ROCCE DI PUNTA PIETRE NERE  E QUELLE CHE SI TROVANO NELLE  
 CAVE DI POGGIO IMPERIALE ( CAVE CHIRO'). LE ROCCE DELLE CAVE CHIRO' PER LA  
 PRESENZA DI TRETRACORALLI DOVREBBERO RISALIRE AL PERMIANO, ULTIMO PERIODO DELLA  
 LORO ESISTENZA. 

   

 Come testimoniato da Primiano therefore, the rock contains pyrite peak black stones, 

 why in some cases and with particular inclination of light shining brightly 

 But what are the pyrites? 

 From wikipedia: The 

pyrite is a very common mineral composed of disulfide of iron (II) (FeS 2 ) which takes its name from the greek word pyros (fire) because it produces sparks when beaten with a piece of metal. Because of the gold was formerly known as the fool's gold , when heated to flame emits a mixture of sulfides from the classic smell of rotten eggs.

It occurs in cubic crystals, or pentagonododecaedrici octahedral, sometimes alternating with faces streaked longitudinally (triglyphs streaks).
are quite frequent germination of various types, including the so-called 'Iron Cross', resulting from the twinning of two interpenetrating pentagonododecaedri.

E 'an alloy of iron and sulfur then. But I also found other examples around the web, and some you'll discover in the course of the next post ....

More photos of First Eagle:
Note: The conclusion that the rocks leading black stones, springs from the Permian age are finding that it did before it, in the quarries Chirò at Poggio Imperiale (photo below).
show that there is a tooth shark or something very similar and right a tetracorallo.

I take this opportunity to thank publicly before Aquilano, primarily for the availability shown me, for the material made available and especially for making me discover something that I did not know, now my search for bands of pyrite in the limestone Acquarotta clearly visible on the sides of the channel.
