| Abstract: | The radiated colony coral fossils with distinctive patterns and colours from Turpan,Xinjiang,is of highly gemmological value.The gemmological characteristics of the coral fossils are studied by using polarizing microscope,micro-hardness tester,EPMA,IR and X-ray powder diffraction.The results show that it is mainly composed of calcite with some dolomite and organic matter(containing methyl and hydroxyl).It is a calcium-based coral fossil.And the cause for the change of cell parameters in calcite is also anal... |
