Zircon Sand. Zircon is used in ceramics, specialty castings and various refractory applications, where its resistance to high temperature and abrasion make it extremely valuable in the manufacturing processes as well as ceramics such as glazes for tiles and sanitary wear.
Sep 11, 2009· Most zircon analyses were carried out using a focused beam and 80-nA beam current. Most of zircon-forming major (Si, Zr) and minor (U, Th, HREE, Y, Hf, P) elements were analysed, together with trace element such as Al, Ca and Fe in order to check the possible contribution of inclusions in zircon analyses.
We present here a test of this method on sediments interstratified with basalt flows of the Taos Plateau Volcanic Field of New Mexico. Nineteen zircons and apatites from two samples of baked sand collected from the uppermost 2 cm of a fluvial channel beneath a flow of the Upper Member of the Servilleta ...
