Abstract:

Based on the study of typical quartz vein type and structural superimposed halo model of blind ore prediction in deep altered rock type gold deposits of Shandong Province，the summarize of its common，we built the ideal structure superimposed halo model of quartz vein and altered rock type，determined five guidelines of blind ore forecast structural superimposed halo.During the prediction，we conducted the follow-up study of multiple gold targets，summaried the reasons of not see mine targets according to projections，revised and improved the forecasting models and the predict sign of blind mine，the forecast was continuously pushed forward into deep deposit.The method of looking for blind ore by structural superimposed halo achieved a new breakthrough both in the theory and methods technical research，not only improved the theory of the method，but also made the techniques more mature.There was a significant prospecting effect by using the method to forecast blind mine in deep deposits.

Key words: Structural superposition halo model, Prediction of deep blind ore, Quartz vein-altered rock type gold deposits, Eastern Shandong
