Direct determination of hydrothermal mineral age to get accurate chronology of hydrothermal ore-forming event,has been the geologists dream.One of the most important problems in theoretical research is the genesis of the deposit irrelative to the time relation of mineralization of surrounding rock,which directly affect the practice of ore prospecting and ore prospecting target area.At present,the most widely used method for study on the metallogenic chronology of application in deposit is isotopic in aitu dating techniques.The laser ablation inductively coupled plasma mass spectrometry in mineralized rocks zircon (LA-ICP-MS) to determine the U-Pb age,either from the principle,test method,this method until the results of treatment are mature,advanced and high precision in home and abroad in the forefront of research,which is now the metallogenic chronology the precise dating.
