The Trompsburg Complex, South Africa: A preliminary three dimensional model

Soil Erosion Rates in South Africa Compared With Cosmogenic 3he-Based Rates of Soil Production

“…Gosse and Phillips, 2001;Niedermann, 2002) and the rock density, ρ = 3.0 g/cm 3 (e.g. Maré and Cole, 2006 He production rates normalised to sea level and latitudes > 60 º are given in Table 3. These values were calculated on a sample specific basis, through the application of the mineral chemistry-dependent production rates proposed by Fenton…”

Seismotectonic Models for South Africa: Synthesis of Geoscientific Information, Problems, and the Way Forward

“…The BA and SCCB show no distinct correlation with earthquakes recorded in the region. A magnetic lineament and a mafic pluton known as the Trompsburg complex (Maré and Cole 2006) can be found within 100 km north of the Koffiefontein cluster. No corresponding magnetic anomalies exist in the vicinity of the Ceres cluster.…”

The geotectonic setting, age and mineral deposit inventory of global layered intrusions

“…The bulk of the intrusion consists of gabbro, which is overlain by magnetite-rich gabbro and titanomagnetitites that host PGE enrichments of up to 15 ppm over 1 m (Maier et al 2003a). Trompsburg is a large, lopolithic layered intrusion (~ 2,500 km 2 ; ~ 1915.2 ± 5.6 Ma; Maré and Cole 2006) identified by a gravimetric survey conducted by Transvaal Orangia Limited in 1946 (Maier et al 2003b). Several boreholes drilled in the 1950s intersected mostly gabbro and troctolite, but also anorthosite with up to 19 magnetitite layers containing up to 1.82% V 2 O 5 .…”
