But the information on the chemicalstates of Fe element in the glaze cannot be obtained effectively through chemical analysisand X-ray diffraction. Detailed analysis on chemical states of the Fe element can be donewith Mossbauer spectroscopy. The phase transformation during the firing process ofsky-green glaze of imitative ancient Ru porcelain has been done with展开更多

W. Alvarez suggested a hypothesis that the falling of a largeextraterrestrial body upon the earth caused the extinction event at the end of theCretaceous, according to the extraordinarily high concentration of Ir in K/T boundarydeposits. Since then, studies have indicated that the iridium anomaly distributeswidely in the sections of this age over the world. However, these studies focused onthe abundance of Ir. Little attention was paid to other platinum group metals (PGM).Analyzing the abundance of Ru in boundary samples is very difficult because of展开更多
