Population bottlenecks are when population size reduces for a short period of time. Overpopulation may indicate any case in which the population of any species of animal may exceed the carrying capacity of its ecological niche.
The name zirconium comes from the mineral zircon, which is the most important source of the metal. The largest deposits of this mineral are found in Australia, Brazil, Russia, India, South Africa and the United States. Australia and South Africa are the largest miners of the mineral.
So, where did they originally come from? This is one of the questions I will try to answer in the coming months after I return to my lab at the museumâs Natural Heritage Campus. The second question is whether or not these Tram Poung zircons came from the same part of the mantle than those in Ratanakiri province. Are they the same age? Same chemistry? Understanding the chemical characteristics of these zircons can tell us a great deal about the mantle deep below the surface.
