The Zambezi River rises at the center of southern Africa, flows across low-relief Kalahari Plateau, meets Karoo basalt, plunges into Victoria Falls, follows along rifts, and pierces through Precambrian basement to eventually deliver its load onto Mozambican passive margin. Reflecting polyphase evolution, river is subdivided segments with different geological geomorphological character, a subdiv...

A fractal (power-law) distribution is the only statistical distribution applicable to a scale-invariant process. One of the major problems in petrology is the distribution of trace elements in the Earth’s crust. Extreme values of this distribution result in ore deposits. There is accumulating observational evidence that tonnage–grade statistics of ore deposits are often fractal (powerlaw). Rayl...

The Taiyuan Formation, located on the northern margin of Ordos Basin, has an important role in reconstructing tectonic paleogeography and evolutionary process due to its preservation information about evolution basin throughout Late Paleozoic. provenance, paleogeography, activity traits Formation were examined using sedimentary petrology zircon chronology methods. Alxa block is consistent with ...
