| 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 |
| 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. |
