| 中文摘要:通常，人们仅习惯于将地质矿产分为内生和外生2大类分别进行研究，而很少将二者联系起来做进一步的比较研究，并探讨它们在形成机制上的异同之处，从而影响了成矿理论的完整性，给矿产地质勘探造成了一定的负面影响，为此，作者试图以美国的卡林金矿带和布莱克海底高原的天然气水合物矿床为例开展矿床分布、成矿条件和成矿特征等方面的系统研究，探讨内生热液矿床与天然气水合物矿床形成机制上的差异与共性，揭示某些内生热液矿床与外生矿床成矿演化的相似性，为进一步完善成矿理论、指导矿产资源的合理开发提供科学依据。 |

| A Comparative Study on Formation Mechanisms of Endogenetic Hydrothermal and Gas-hydrate Deposits——Evidence from Carlin Trend Gold Deposits and Gas-hydrate Accumulations of Blake Ridge, USA |

| Abstract:People are usually accustomed to dividing the geologic deposits into the exogenetic and endogenetic ones and study them separately rather than compare them and probe into the common characters and differences between them. As a result, mineralization theories are imperfect and exert an unfavorable effect on mineral exploration. In view of this, this paper, based on a study of the distribution, metallogenic conditions and mineralizing features of the Carlin Trend gold deposits and gas hydrate deposits of Blake Ridge, USA, tries to inquire into the differences between the formation mechanism of endogenetic hydrothermal deposits and that of gas hydrate accumulations as well as their common characteristics, thus revealing some similarities between them, perfecting the mineralization theories and providing scientific basis for rational exploration and development of mineral deposits. |
