Depositional and tectonic setting of the Archean Moodies Group, Barberton Greenstone Belt, South Africa.
The 3.22-3.10 Ga old Moodies Group, uppermost unit of the Swaziland Supergroup in the Barberton Greenstone Belt (BGB), is the oldest exposed, well-preserved quartz-rich sedimentary sequence on earth. It is preserved in structurally separate blocks in a heavily deformed fold-and-thrust belt. North of the Inyoka Fault, Moodies strata reach up to 3700 m in thickness. Detailed mapping, correlation ...
متن کاملArchean spherule layers in the Barberton Greenstone Belt, South Africa: A discussion of problems related to the impact interpretation
This review of the current knowledge of impact spherule layers in the Barberton greenstone belt, together with new petrographic, geochemical, and field data on a number of impact and volcanic spherical particle horizons, highlight a number of problems with the proposition of frequent and large meteorite impacts during mid-Archean times. Field data indicate that some of the four previously propo...
متن کاملAtmospheric sulfur in Archean komatiite-hosted nickel deposits.
Some of Earth's largest iron-nickel (Fe-Ni) sulfide ore deposits formed during the Archean and early Proterozoic. Establishing the origin of the metals and sulfur in these deposits is critical for understanding their genesis. Here, we present multiple sulfur isotope data implying that the sulfur in Archean komatiite-hosted Fe-Ni sulfide deposits was previously processed through the atmosphere a...
متن کاملGenesis of Magnetite Deposits I N the Iron Mask Batholith
Significant magnetite, in the form of dyke-like lodes (Cockfield. 1948). occurs in close spatial relationship to copper deposits such as the Afton mine. The genetic relationship of these massive magnetite lodes to the copper deposits of the Iron Mask is unknown, as i s the origin of the magnetite deposits. However, the proximity of these deposits to magnetite-rich intrusive units of the Iron Ma...
