A structural investigation of the well-exposed northern and western parts of the Vredefort dome has established the geometry and chronology of pre-, syn-and post-impact deformation features. The strata display a crude polygonal geometry with zones of complex monoclinal or symmetric folding, and radial oblique-slip faulting separating relatively straight segments. Pseudotachylitic breccia is ubi...

Introduction: The lunar meteorites Miller Range 05035 (MIL) and Meteorite Hills 01210 (MET) were collected during the 2005 and 2001 ANSMET (Antarctic Meteorite Search) field seasons [1,2]. MET is a 22.8 g regolith breccia composed primarily of basaltic material [3-6]. MIL is a 142.2 g coarse-grained basalt [2]. The bulk composition, mineral assemblage, and texture of MIL is similar to lunar met...

Abstract Bener Dam Diversion Tunnel is located in two rock units such as andesite and breccia. Based on the engineering geology investigation, subsurface tunnel will penetrate breccia with good mass quality (fresh-moderately weathered), while surrounding consist of breccias moderate poor quality. Geological conditions are used basis for stability analysis excavation methods determining primary ...

Introduction: Olivine vitrophyres are impact melts, consisting of Lunar highlands and KREEP-rich materials, that are primarily composed of olivines in an opaque glass, sometimes with lath-like plagioclase crystals [e.g. 0-2]. Petrographically, these are similar to vitrophyric Apollo 14 high-Al basalts [11]. The purpose of this study was to use olivine chemistry and petrographic evidence in orde...
