...G. Kwiatek; K. Plenkers; G. Dresen; JAGUARS Research Group Abstract We investigate the source parameters of picoseismic and nanoseismic events ( M w >-4.1) recorded with a high-sensitivity seismic network at the Mponeng gold mine in South Africa to gain new insights into the scaling of small...

...Figure 1. Sketch of the location of the JAGUARS network in the Mponeng gold mine and its surrounding geologic formations. The JAGUARS network is located at 3540 m depth. The sensors are located in boreholes that are shown as bold black lines. The PG dike is shown in gray. The gold reef...

...Figure 1. (a) Mining activity in the vicinity of JAGUARS’ network (ellipse N). The tunnels at 3543 m depth are shown using thick black lines. The support pillars are marked light gray and the Greater Green Dike is shown in dark gray. The mined areas (A and B) are surrounded with dashed rectangles...

... correspond to a stress drop of 3 MPa. This falls in typical ranges for natural earthquakes (e.g., Kanamori and Anderson, 1975 ) and mining-induced earthquakes (e.g., Yamada et al. , 2007 ). Acoustic emission data used in this study were collected by the JAGUARS network in the Mponeng gold mine...

... of Cu, Zn and Pb (10–30 m) in the weathered zone ( Greig 1982 ). The Jaguar deposit lies under a sheetwash plain mantled by coarse polymictic lag of vein quartz, ferruginous nodules, pisoliths, and lithic fragments ( Fig. 3 ). A well-developed network of tree-lined drainage channels traverses...

..., the 2.698 Ga Bounty Igneous Complex, and the 2.69 Ga Defiance dolerite. In the Gindalbie terrane, the 2.692 Ga Jaguar dolerite is hosted in pillow basalts that are part of the bimodal Teutonic Bore volcanic complex. The remaining sills are hosted in sediments emplaced in a subaqueous setting, largely around...
