.... Their map of the Komati Formation shows the large-scale interlayering of komatiites and basalts, offsets along faults, and consistent younging to the north with no structural repetition ( Viljoen and Viljoen, 1969a ). The top and bottom of the Komati Formation are marked by the Middle Marker (MM) chert...

... such as the Inyoka-Saddleback fault system. High resolution 2D conductivity images along selected profiles suggest that some faults might continue further south into the granitoids of the Mpuluzi batholith, implying that the batholith was emplaced along faults (Inyoka-Saddleback fault system and/or Komati Fault...

The mainshock is represented by a finite‐fault solution obtained by inverting strong‐motion and Global Positioning System data, testing both 1D and 3D wavespeed models for central Italy. Surface topography, attenuation, and the Moho discontinuity are also accommodated. Including...

... by the Nelshoogte Schist Belt. These rocks have, in the past, been correlated with the c . 3500 Ma lithologies in the lower division of the Barberton Supergroup ( viz ., the Tjakastad Subgroup of the Onverwacht Group in the Komati River type locality). Recent studies elsewhere in the Barberton region (including...

... (1997) demonstrated that abrupt changes of fault slip and/or tensile fracture can generate rotational seismic waves. There are few observational evidences of how significant rotations may be in near-source regions (see, e.g., Nigbor, 1994 ; Takeo, 1998 ; Huang et al. , 2006 ). Furthermore, several...
