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 ...

Petrology and Mineral Compositions: The fresh, pale gray interior of this specimen has multiple shock fractures (with very minor calcite coatings) and some thin glass veinlets (Figure 2). This rock is a poikiloblastic recrystallized breccia, with larger grains of plagioclase (~70%) enclosing much smaller grains (less than 100 microns across) of pyroxene (~20%), olivine (~10%) and accessory Ti-c...

There is a great need for more precise absolute ages for sedimentary rocks. We have been actively involved in developing techniques to directly date sedimentary rocks, rather than using associated igneous rocks, or using relative dating techniques. Sedimentary phosphate nodules (i.e. coprolites) are ideal candidates for absolute dating of sedimentary rocks. Phosphates occur commonly within the ...

Two-dimensional lattice particle models have been used to simulate dynamic thrust faulting and its effects on near-fault ground motions. The lattice particle modeling approach has been demonstrated as an efficient way to model the dynamic rupture phenomena observed from a foam rubber experiment on dipping faults. We constructed a 42 dipping fault model to simulate near-fault ground motions unde...
