Abstract |
: |
Mineralogical composition of 295 samples of Atlantis II, Deep
metalliferous sediments was studied by X-ray diffraction analysis. Various
types of silicates, iron and manganese oxides, carbonates, sulfates, sulfides
are the common mineral phases. The minerals exhibit systematic distribution
pattern in the sediments cores and facilitate a facies and subfacies classification.
Typical mineralogical sequence from bottom to top is: sulfides,
silicates, siderite, Ca-Fe-Mn carbonate, rhodochrosite, iron oxides, manganite
and amorphous silica, iron or manganese oxides. Mineralogical varia- I
tions in the Atlantis II, Deep sediments are considered to be due to the pre- !
sence of repeated depositional cycles related to fluctuation in temperature,
pH and perhaps oxygen fugacity, during the mixing of magmatic hydrothermal
solution and sea-water. |
