| 摘 要： | 矿产预测是科学勘查工作不可少的环节。矿产预测的成功率取决于人们对矿产规律性的认识、所收集到的各种信息是否足够和以此建立的预测准则是否可靠和实用。物探、化探在矿产预测时要充分开发、利用资料中直接和间接找矿两类信息,具体可采用填图—目标物模型类比法、目标物标志信息统计法和目的物异常推断法。为推进矿产预测要充分利用已有的区域物探、化探资料,进行联片解释；系统开展大比例尺物探、化探工作；建立地质—地球物理—地球化学模型和预测准则；及时验证预测及推断；扩大和更新知识、培养综合人才是当务之急。

| Abstract: | : Prognosis of ore resources is an indispensable link in scientific exploration. The success rate of ore prognosis depends on people's knowledge of ore resource regularity, the sufficiency of various sorts of information collected, and the reliability and practicability of criteria f or prognosis established on such a basis. In the application of geophysical and geochemical prospecting to the prognosis of ore resources, we should fully develop arid utilize direct and indirect ore-prospecting information in the data, and employ such methods as mapping-target model analogy, target indicating information statistics and target anomaly inference in practice. In order to push ahead with the prognosis of ore resources, we should utilize the available regional geophysical and geochemical data to the fullest extent and make interpretation on a combined and integrated basis. The systematic performance of large-scale geophysical and geochemical prospecting work, the establishment of geological-geophysical-geochemical models and prognostic criteria, the timely verification of prognostic results and the making of inference, the expansion and renewal of our knowledge and the training of qualified researchers seem to be the mast pressing tasks at present. |
