The zone extraction method teaches you all the needed protocols to extract teeth but when it comes to removing implants, the methodology is different because implants are "anchored" to the jaw. In this training, Dr. Simon will teach his explantation system for different scenarios. You will learn how to remove failed implants safely and with ...

The geometry of mineral deposits can give insights into fluid flow in shear zones. Lode gold ore bodies at Renco Mine, in the Limpopo Belt, Zimbabwe, occur as siliceous breccias and mylonites within amphibolite facies shear zones that dip either gently or steeply. The two sets of ore bodies formed synchronously from hydrothermal fluids. The ore bodies are oblate, but …

The NMZ is separated from the Zimbabwe craton by a major reverse-sense shear zone (James 1975; Coward et al. 1976) called the North Limpopo Thrust Zone (NLTZ) (Blenkin-sop et al. 1995). Granulite facies metamorphism, regional NW–SE shortening, and reverse faulting occurred at the

Introduction: Importance of AEZs in guiding agricultural practices, natural resource management, and policy planning. Revised AEZs: Updated classification into six primary zones: Region I, IIa, IIb, III, IV, Va, and Vb. Key Changes: Increased detail with subdivision of Region V into Va and Vb. Emphasis on climate adaptation strategies. Use of modern GIS-based mapping techniques.

generally comprise shear zones which are in-filled with gold-bearing sulphides and quartz. The mineralised zones are up to 1 m in width, have average grades of 4– 5 g/t. Mazowe Mine is one of the oldest mines in Zimbabwe, and exploration and development in this region dates back to 1890, with over 1.4 million ounces of gold produced to date.
The agroclimatic zones which will be used in this paper are based on a combination of Zimbabwe's rainfall map and the agro-ecological zones described by Vincent and Thomas (1960). An examination of the two maps (Figures 1 and 2 ) shows that the agro-ecological zones are very closely related to rainfall.

For agriculture to develop in a sustainable way in Zimbabwe, there a need to reclassify its agro-ecological zones. The current zones developed in the 60s have become redundant, outdated and cannot be used to plan sustainable agriculture. This is because of climate change and variability and which has shifted previously derived zones and the development of new tools and …
