Foidite

Caratteristiche delle foiditi

Chimismo: basico alcalino

Struttura e Tessitura: afanitica olocristallina o ipocristallina, generalmente porfirica

Gruppo di classificazione: roccia magmatica effusiva
Caratteristiche macroscopiche: 

  • Colore:  grigio, grigio chiaro
  • Saggi distintivi: attaccabile con HF, lavabile con HCl

Minerali costituenti

Essenziali: nefelina/leucite, clinopirosseno (augite, diopside o aegirina)
Accessori: plagioclasio, sanidino, mellilite, titanite, apatite, flogopite, perovskite, analcime e sodalite
Minerali accidentali: ndc

Viste

  • in situ
  • in sezione sottile
    • a nicols paralleli
    • a nicols incrociati

Ambiente di formazione e giacitura

Giacitura: tipica di rocce effusive (depositi lavici)

Fomazione: in numerosi ambienti geodinamici con caratteristiche chimiche molto variabili. Per processi di contaminazione crostale e cristallizzazione frazionata ma anche per cristallizzazione diretta da magmi provenienti dal mantello senza contaminazione crostale. Tali magmi possono risalire ad esempio in zone di rift continentale.
