| A new round of making ore search nearby is proposed in this paper based on previous prospecting history from 1950’s to 1960’s. The new round of making ore search nearby has its new characteristics. Deep prospecting is a type of making ore search nearby. Crustal Continuum Model, deep fluid function (mineralization), and metallogenic level provide a theoretical basis for the new round of making ore search nearby. Success in ore prospecting was achieved both in China and abroad, especially in Hunan Province. This paper sums up some experience of deep ore prospecting criteria in three aspects, i.e., minerals and mineral assemblages, granite metallogenic specialization indicators, identification of mantle-origin deposit marks. In addition, identifying the deep mantle source marks of ore-forming fluids, strengthening the study of the metallogenic regularity, updating the concept, and the introduction of new technology and new method deserve much attention in the actual deep ore-prospecting work. |
