magmatic deposits meaning in English
岩浆矿床
Examples
- The accumulation and evolution of metallogenic series of the mafic - ultramafic magmatic deposits in china
超镁铁岩浆矿床成矿系列的聚集与演化 - In china , it is more prominent , about 86 % amount of nickel , 90 % amount of platinum metals , 7 . 3 % copper comes from nickel - copper sulfide magmatic deposits
我国的情况更为突出，镍金属储量近86 、铂90以上、铜约7 . 3均来源于铜镍硫化物岩浆矿床。 - The main source of nickel and platinum metals in the world is the nickel - copper sulfide magmatic deposits related to basic - ultrabasic body , which provide half or more amount of the metals in the world
世界镍和铂族金属的主要来源是与基性超基性岩有关的铜镍硫化物岩浆矿床。该类矿床占世界镍、铂量的近一半或更多。 - There are plentiful mineral resources of nickel , cobalt , and copper in the northwest region of china , specially jinchuan superlarge copper - nickel sulflde magmatic deposit in gansu province , known for its large scale and typical metallogenetic feature in the world , is an important source of ni - cu metal mineral resource in our country . in contrast , jianchaling large cobalt - bearing nickel sulflde deposit in shannxi province is not famous and unmined , but many problems about the deposit are researched because of its special geologic settings and mineralization characteristic
我国西北地区有着丰富的镍、钴、铜等金属的矿产资源，尤其是甘肃省金川超大型铜镍硫化物岩浆矿床，以其超大规模及其典型的成矿特征而闻名于世，是我国重要的镍、铜金属矿产基地，而相比之下，陕西省煎茶岭大型镍(钴)矿床规模较小且未开采，但因其独特的地质背景和成矿特征而具有重要的研究意义。 - On the basis of systematic analysis and comparative research on jianchaling and jinchuan nickel sulflde deposit in geology and geochemistry , some conclusions can be drawn as follow : ( 1 ) re - os isotopic geochronology data define an precise 878 ? 6 ma isochon , suggest jianchaling nickel sulflde deposit would form in new proterozoic . the rock - forming process and metal logenesis happened on the whole , this deposit subordinates to magmatic deposit
通过对煎茶岭和金川镍矿床地质、地球化学的系统分析与比较研究，取得以下新的认识和进展： ( 1 ) re ? os同位素地质年代学研究表明，煎茶岭硫化镍矿床形成于878ma前的新元古代，成矿作用和成岩作用基本上是同时进行的，属岩浆矿床。
