Our understanding of the geology of Victoria Falls and surroundings is underpinned by the meticulous studies and exceptional field observational skills of a remarkable group of geologists. Initial geological field investigations were carried out by AJC Molyneux and GW Lamplugh in the early 1900’s. HB Maufe (in 1938) made exceptionally detailed descriptions and prescient interpretations of the Kalahari beds exposed in railway cuttings just south of Victoria Falls Station. Seventy-five years later, these are arguably still the best available records of these enigmatic sediments.
This is located on the marginal facies of the harzburgite of Cyclic Unit approx.
A 1.2km diameter circular structure was visited by the Geological Society in Ocotber 2008 to look for evidence of a meteorite impact.
No conclusive evidence was found.
See the attached document with photos of the various features of the structure. Despite the confident tone of this document, this structure has not been confirmed as an impact site.
Contact between Great Dyke and country rock granites, striking 022 and dipping 60 degrees East. Mafic intrusion along the contact in places.
Following discovery of alluvial gold at Tarka Forest in 2004 and subsequent acquisition of a Special Grant over the area by the Zimbabwe Mining Development Corporation, a lot of interest was roused on the gold potential of the Chimanimani area. This resulted in DTZ-Ozgeo, a company specialised in alluvial minerals, securing a Special Grant (SG 4955) in 2007 to explore for gold in an area encompassing Charleswood Farm adjacent to Tarka Forest, about 15 km east of Chimanimani.
