| contents | The sulfide deposit at Site 471 occurs between overlying pelagic sediment and underlying basalt. The deposit is vertically zoned and consists, from top to bottom, of the following mineral assemblages: (1) pyrite, chalcopyrite, and Zn-sulfide in chert and calcite gangue (~ 35 cm thick); (2) a 5-cm-thick metalliferous sediment layer and (3) a 4-cm-thick chert layer. The calcite gangue appears at a later stage than chert gangue in the sequence of deposition, also filling in voids and fractures. The manganese content of calcite is particularly high and varies systematically, reaching a maximum at the top of the massive sulfide portion of the deposit. |
