摘要
准噶尔南缘阜康地区二叠系芦草沟组广泛分布深湖—半深湖相油页岩。阜康地区油页岩研究区处于准噶尔古台坳—博格达晚古生代裂陷槽的构造过渡位置,大型逆冲断层作用导致二叠系油页岩出露地表。阜康地区矿体工业类型为有机沉积层状矿床。油页岩层系由老到新可大致划分为4段,优质油页岩集中在第二、三段。采用不同指标进行的微量元素分析结果显示,根据Sr/Ba比值判断绝大部分油页岩样品也是陆相产出;根据硼元素含量可以确定油页岩以淡水沉积环境为主,只是间或有海水介入。该地区油页岩具有特别高的开采价值。
Deep or semi-deep lacustrine oil shale is widely distributed in the Permian Lucaogou Formation in Fukang area on southern margin of Junggar Basin. Fukang research area of oil shale is located at the structural transition area between paleo-syneclise and Late Paleozoic Bogda faulted depression trough. Permian oil shale crops out due to large-scale reversed slip faults. Commercial types of ore bodies are organic sedimentary bedded deposits. Oil shale strata can be divided into four segments from old ones to new ones, as well as high-quality oil shale concentrates in the second and third ones. Trace elements analysis based on different indicators shows that most oil shale samples are categorized as land facies judged by the ratio of Sr/Ba. Baron content shows that oil shale mainly exists in freshwater sedimentary environment but with sea water effect occasionally. Fukang oil shale has extremely high value for production.
