STUDY ON THE METALLOGENIC EPOCH OF THE JINDING LEAD－ ZINC DEPOSIT WITH APATITE FISSION TRACK ANALYSIS

： Fission track analysis of minerals may be effective in the study of the metallogenic epoch of hydrothermal deposits.There exist different views on the metallogenic age of the Jinding super－ large lead－ zinc deposit.Taking the Jiayashan ore block as an example,the paper studied the metallogenic epoch of the Jinding lead－ zinc deposit with apatite fission track analysis.The result shows that the metallogenic age of the Jinding lead－ zinc deposit is the Eocene,and later,the deposit had undergone thermal disturbance of the Himalaya orogenic movement.
