  1. uvjeti (p, T, x) u kojima će neki minerali koegzistirati • koje će mineralne vrste biti stabilne u točno definiranim uvjetima Dijagrami stabilnosti minerala

  2. Osnova za konstruiranje dijagrama stabilnosti minerala 1. Zakon o očuvaju masa 2. Veza između Gibbsove slobodne energije i konstante ravnoteže • realne otopine → aktivitet (a = g×c) • realni plinovi → fugacitet (f = g×p)

  3. Kemijsko trošenje feldspara mikroklin kaolinit DGR0 = 7,103 kcal K = ?

  4. Utjecaj temperature na konstantu ravnoteže Van’t Hoffova jednadžba:

  5. Dijagrami topljivosti Otapanje - kongruentno - inkongruentno primjer dolomita (MgCa(CO3)2) Kako se otapa mikroklin? KAlSi3O8 + 7H2O + H+ → K+ + Al3+ + 3Si4+ → K+ + Al(OH)3 + 3H4SiO4 Kako se otapa gibbsit?
