| 中文摘要:<正> 马坑铁矿赋存于石炭—二叠纪合火山岩的碳酸盐岩—碎屑岩建造的地层中,由辉绿岩和大理岩在火山气热液作用下形成含矽卡岩矿物组合的磁铁矿床。这类铁矿分布较广,是一个重要的矿床类型。为了探索这类矿床形成的温度、压力和介质环境,我们继《福建马坑矽卡岩分带的模拟实验》之后,采用马坑天然辉绿岩和大理岩作为试料,对该矿床形成的温度和压力进行了初步的实验研究。 |

| A PRELIMINARY EXPERIMENT ON THE FORMATION TEMPERATURE AND PRESSURE OF THE IRON DEPOSIT IN MAKENG,FUJIAN |
|
|
| Abstract:The natural diabase and marble which are closely related with the ore-forming process are used as starting materials in our simulated experimentbasing on the geological characteristics of Makeng deposit. All experimentswere carried out in cold seal pressure vessels with gold lines, the reagentsbeing acidic, neutral and basic aqueous solution. Temperatures of the experi-ments ranged from 300 to 650℃, pressures 300-650 atm and durations of theexperiment was 168 hours. |
