On ore-search breakthrough for Baiyinchang type massive sulfide deposit

By studying the history of prospecting and ore rehunting in Baiyin orefield and analysing the ore-searchth inking at different periods, some successful experiences and failing lessons during the ore-hunting practice are sumed up.Thus is not only enriched the geology and ore-hunting theory, but also layed a foundation for ore rehunting at present conditions.Especially, under the guidance of academic thought "Subm arine volcanic apparatus-hot brine circulation dynamics" in recent years, new Cu-riched ore bodies have been discovered in the deep of the west segment of Xiaotieshan deposit, and in the deep of Zheyaoshan deposit, indicating that there is broad ore-hunting prospect in the deep of economic deposit existed and its surroundings.The basis for ore rehunting is provided by renewal the ore hunting thinking.
