Titre : Great Dike, Zimbabwe January 1993
Description : (La description de cette image n'existe qu'en anglais)
The Great Dike of Zimbabwe is a linear geological feature that is easily recognizable running 300 miles (483 kilometes) north-south through the midsection of Zimbabwe. This photograph shows only the southernmost extent of the Great Dike. The highly mineralized composition of the dike (igneous rock) makes this an important economic region for Zimbabwe. Copper, asbestos, chromium, gold, and platinum are some of the minerals that make up the strategic mineral reserves found throughout this region. Some of the lighter brown areas in this photograph are large areas of overgrazed tribal trust lands that are scattered throughout Zimbabwe. There is also visual evidence that east-west surface displacement (faulting) has occurred at several points along the Great Dike. Much narrower, paralleling mineralized veins observed east and west of the Great Dike exhibit the same horizontal displacements as the much broader dike.
