| 摘 要： | 与岩浆热场有关的成矿组合是一个新概念，是指在一个或大或小的区域内，在岩浆活动集中的时间段范围内，在岩浆热场的统一作用下所形成和影响的所有矿床，不论成因和矿种，均属于一个成矿组合。与岩浆热场有关的成矿作用主要包括下列几类： 岩浆热液矿床、岩浆热场叠加的沉积矿床、岩浆热场叠加的变质矿床、岩浆热场叠加的能源矿床（藏）以及热泉型矿床等。与岩浆热场有关的成矿组合把金属与非金属成矿作用联系起来，把无机与有机成矿联系起来，把热液与沉积成矿联系起来，把热液与变质成矿联系起来，把金属与能源（燃料）成矿联系起来。这种成矿组合的分布有两种趋势： 一是纵向上的由不同温度构成的成矿组合，如钨锡—铅锌组合、锡—铜组合等； 二是横向上的由相同温度不同矿种构成的成矿组合，如钨锡—石墨组合、金—铜—煤组合、铅—锌—煤组合、油—气—煤—铀组合等。成矿组合强调综合找矿的思路，在找矿时，除了注意主要矿产的找矿外，还应当注意其他矿产和矿种的找矿。在找金属矿床时，注意非金属矿床、沉积叠加改造矿床、变质叠加改造矿床以及能源矿床找矿的可能性。在研究高温金属矿床时，注意与高温成矿相伴的其他矿种成矿的可能性，注意低温金属矿床成矿的可能性，注意与低温成矿作用相伴的其他矿种成矿的可能性。开阔找矿的思路，就不能拘泥于本行本专业，而是围绕岩浆热场，将找所有可能出现的矿为己任。

| Abstract: | Metallogenic assemblage related to magma thermal field is a new concept related to the distribution of temperature gradient of magma thermal field. In the period of magmatic activity concentration range， all of the deposits are formed and influenced by magma thermal field， regardless of the genesis and types of ore deposits， all belong to a metallogenic assemblage. It includes magmatic hydrothermal deposit， sedimentary deposits superimposed by the magma thermal field， metamorphic deposits superimposed by the magma thermal field， energy deposits superimposed by the magma thermal field and hot spring deposits. Metallogenic assemblage related to magma thermal field links metallization with nonmetallic mineralization， organic mineralization with inorganic mineralization， hydrothermal mineralization with sedimentary mineralization， hydrothermal mineralization with metamorphic mineralization， metallization with energy metallization. There are two kinds of distribution of the metallogenic assemblage trend， one is from high to low temperatures in longitudinal sections， such as W—Sn—Pb—Zn combination， Sn—Cu combination； anther one is composed of different minerals metallogenic combination in transverse sections， such as W—Sn—graphite combination， Au—Cu—coal combination， Pb—Zn—coal combination， oil—gas—coal—U combination. Metallogenic assemblage emphasizes comprehensive prospecting. In prospecting， in addition to pay attention to the main mineral prospecting， we should also pay attention to other minerals and mineral prospecting. Looking for metal deposits， we should pay attention to the nonmetallic deposits， sedimentary superimposed deposit， metamorphic deposits as well as the possibility of energy mineral deposits. Looking for high temperature metal deposits， we should pay attention to the possibility of other minerals accompanied by high temperature mineralization， the possibility of low temperature metal deposit mineralization， the possibility of other mineral accompanied by low temperature mineralization. Around the magma thermal field， looking for all possible deposits is our own duty. |
