摘　　要：20世纪70年代以来,大型、超大型矿床研究是当今地学界的热门话题之一,在我国开展全国性大型、超大型金矿综合信息成矿预测尚属首次。本文利用全国地质、地球物理、地球化学和遥感等资料,按照"鹤立鸡群"的观点,以大型、超大型金矿床密集区为模型单元,以金矿床密集区和异常密集区为预测单元,在充分分析控矿因素的基础上,构造刻划矿床变大、变富的因变量,应用双重逐步回归分析方法,对全国大型、超大型金矿开展了定量预测。The issue of giant ore deposits is one of 'hot points' in the geological science in the world since the 1970s. The research work of giant gold deposits prediction in China is carried out for the first time. In this paper,authors make full use of all geological,geophysical,geochemical and remote-sensing information, and according to the viewpoint 'Cranes stand in the chicken's flock', take giant gold deposits concentrated areas for the model units and the gold deposits or anomaly concentrated areas for the prediction units. On the basis a of full analyses of the factors controlling ore deposits, the dependent variables that indicate an the ore deposit to become larger and richer are described. Giant gold deposits are prognosticated all over the country quantitatively with the method of double stepwise regression analysis.
