| 中文摘要:直接信息是最可靠的找矿信息，在矿产勘查中必须起先导的作用。直接信息与间接信息在一定条件和环境下可以互相转化的，只有在信息具有直接指示矿床存在和分布的特性时，它才会发挥实际的找矿效能。因此，多学科信息的收集和综合分析，是信息找矿战略实施的核心。信息找矿战略可以表述为“针对巨型矿床勘查，我们应当瞄准隐伏矿和难识别矿，以直接找矿信息（化探资料）为先导，综合地质和地球物理信息，迅速掌握全局，逐步缩小靶区，直至找到大型特大型矿床。” |

| Abstract:The statistical data from 100 large or super large deposits outside China show that geological mapping, geochemical method and geophysical method and conceptual model played an important role in 77%, 74%, 34% and 23% of the discoveries, respectively. It can be concluded that direct information is the most reliable information. Under a certain condition, the transformation will take place between direct information and indirect information. Only when information indicates the distribution and presence of deposits can it play a role in mineral exploration. Integration and analysis of multiple disciplines seem to be the key to realize information exploration strategy. Information exploration can be described as follows: We should pay attention to the buried deposits and the almost indiscernible deposits; exploration is guided by direct information (geochemical method) from strategic reconnaissance for reducing targets to tactical surveying for pinpointing drill sites until the giant deposit is discovered. |
