川西北地区金矿床的双源复合成矿新认识

川地区金成矿受构造－岩相和构造－岩浆双重控制。据该区金矿的产出特点和成矿特征，可将区内金矿（点）划分为层控型、岩控型和双控型。在进行区域成矿分析时应注重构造－岩相和构造－岩浆的致矿、控矿作用，任何片面怀的成矿分析都可能导致成矿认识的简单化和肤浅化。双源复合成矿概念的提出与应用，有助于对本区成矿认识的深化和研究水平的提高。

NEW UNDERSTANDING OF DOUBLE-SOURCE COMPLEX GOLD MINERALIZATION IN NORTHWEST SICHUAN

The gold mineralization in the northwest Sichuan Province is controlled by both tectonics lithofacies and tectonics magma.The occurrence and mineralization features of the gold deposits (prospects) in this region may be used to classify them into the strata bound,the magma bound,and the doubly bound types.In the analysis of the regional mineralization,stress should be laid on the comprehensive orogenic and strata bound effects of the tectonics lithofacies anomaly and the tectonics magma.Any one sided mineralization analysis may lead to the simplification of the understanding of the mineralization.The proposal and application of the double source complex mineralization may deepen our understanding of the mineralization of this region and raise our present research to a higher level.
