  • Petrifaction - Wikipedia

    The minerals commonly involved in replacement are calcite, silica, pyrite, and hematite. It is rare to find organisms preserved by replacement alone (as opposed to in combination with permineralization), but these fossils present significant importance to paleontologists because these fossils tend …

Several trace elements including As, Au, Bi, Co, Cu, Ni, Pb, Sb, Te, and Tl were detected in more than half of the LA-ICP-MS analyses of all pyrite types. Pyrite …

  • Phase heritage during replacement reactions in Ti-bearing

    Mar 04, 2021· These have in turn been replaced by pyrrhotite ± pyrite in the most altered parts of the system. The sample examined here is taken from igneous zone 3 (sample 250 of Polito et al. 2001; see their Fig. 3) and contains an alteration assemblage biotite, chlorite, calcite, albite, ilmenite and pyrrhotite.

  • Experimental investigation of the reactions between pyrite

    Apr 01, 2021· Previous experimental studies of pyrite replacement have invariably used Cu(II) rather than Cu(I) as the aqueous reactant. Replacement of sulfides by aqueous Cu(II) is the dominant mechanism for the formation of supergene enrichment zones in porphyry Cu deposits, where fluid temperatures are low and meteoric water is oxic.
