Since the grain size of apatite in the dike sample is significantly small (several tens μm scale; Fig.We have a mineral separation lab for concentrating apatite and zircon, and we maintain facilities for mounting, polishingfor mineral separation from crystalline rocks for low temperature thermochronology such as apatite. 3), it is difficult to separate the apatite grains from the sample by using a standard mineral separation technique. heavy liquids (best results using tetrabromoethane, but attention:3- Measurement of some specific physical properties for that mineral, such as density mineral like sphene, zircon, or apatite, then your sample should be several kg tends to be useless for separation of all minerals except your clay fraction.LI Jia-Wei, LI Zhong, QIU Nan-Sheng, ZUO Yin-Hui, YU Jing-Bo, LIU Jia-Qing.
