Abstract and Figures. Detailed structural data from the Midlands greenstone belt show that, in contrast to pre-existing models, the evolution of the greenstone belt involved an early episode ofThe existing 865 gravity data points from the African Gravity Project (AGP) data base (Fairhead et al., 1988) were considered inadequate for the study of the configuration of the greenstone belts and the regional crustal structure of the area as most of them come from traverses across the Great Dyke and the Belingwe greenstone belt (Fig. Gravity anomaly patterns in the south-central Zimbabwe

Gravity anomaly patterns in the south-central Zimbabwe
The granite-greenstone terrain of south-central Zimbabwe, encompassing the Belingwe (Mberengwa) greenstone belt and sections of the Great Dyke, provides important constraints on models for the evolution of the Zimbabwe craton and the Archaean crust in general. In this paper we enhance and model existing and recently acquired In total, 69 detrital zircons from two metasedimentary rock samples overlying the angular unconformity in the greenstone belt, a basal quartz–jasper metaconglomerate 332-1 and a quartzite 335-1Earth's oldest stable crust in the Pilbara Craton formed by

The Belingwe belt in Zimbabwe is probably the best preserved late Archaean greenstone belt known.

Geology and metallogeny of the Barberton greenstone belt:
The morphology and mineral chemistry of gold and associated sulphides at Sheba, Fairview, and New Consort gold mines in the Barberton Greenstone Belt (BGB) identify two main types of mineralization. The first type occurs associated with sulphides (mainly pyrite), either as inclusions (10–30 μm) or as sub-microscopic gold.Re-Os data and PGE concentrations as well as Mo concentrations and isotope data are reported for suites of fine clastic sediments and black shales from the Barberton Greenstone Belt, South Africa (Fig Tree and Moodies Groups, 3.25–3.15 Ga), the Belingwe Greenstone Belt, Zimbabwe (Manjeri Formation, ca. 2.7 Ga) and shales from PGE, Re-Os, and Mo isotope systematics in Archean and

The modelling also indicates that these belts, and possibly all the belts in the study area (based on comparable densities and anomaly amplitudes), have limited depth extents in the range of 3–5 km.The Midlands greenstone belt (MGB) in the central Zimbabwe craton represents the largest greenstone outcrop (Fig. 1), with the highest concentration of gold mines in Zimbabwe (e.g. Foster et al., 1986, Campbell and Pitfield, 1994).
