摘　　要：夕卡岩矿床是一种具有重要工业意义的矿床类型 ,是世界上富铁矿、钨、锡、铋、铅锌、金和金云母、透辉石、硅灰石等金属和非金属矿产的重要来源。这类矿床不仅分布广泛、矿物组合特殊 ,而且包含有内生成矿作用许多复杂的成因信息。因此 ,一个多世纪以来国际上对夕卡岩矿床的研究长盛不衰 ,不断有所创新。文章回顾了近二十年来 ,在成矿的构造背景、矿床的多成因性、岩浆期和岩浆夕卡岩、碱交代与成矿、交代分带、含银铅锌锰质夕卡岩。Being an important industrial type of mineral deposits, skarn deposits serve as the main sources of such metallic and nonmetallic ores in the world as high_grade iron ore, tungsten, tin, bismuth, zinc_lead, gold, phlogopite, diopside, and wollastonite. This type of mineral deposits is not only widely distributed and quite unique in mineral paragenesis but also contains much complicated genetic information of endogenous mineralization, Therefore, investigation on skarn deposits has been continued without interruption for more than one century, constantly bringing forth new ideas. Especially in the past two decades, the research of skarn deposits has made much important progress in such aspects as tectonic settings of skarn mineralization, multigenesis of skarn and skarn deposits, skarn of magmatic stage and magmatic skarn, alkali metasomatism and skarn mineralization, metasomatic zoning, Ag_Pb_Zn_bearing manganoan skarn formation, Au_bearing skarns, and ore_bearing skarn evaluation criteria. The above_mentioned new important progress in the skarn deposit studies has important theoretical significance in further understanding their petrogenic and metallogenic mechanism and practical applied value and hence in prospecting for more concealed skarn deposits.
