摘要
在湖泊中存在三种三角洲类型 ,即正常三角洲 ,辫状三角洲和扇三角洲。它们均由三角洲平原、三角洲前缘、前三角洲三部分所组成。陆相地层具有强烈的旋回性 ,只要将基准面看成海平面就完全可以运用层序地层学思路与方法研究陆相地层。扇三角洲相在断陷湖盆的陡坡一侧发育 ,通过与标准三角洲副层序模式对比 ,一个完整的扇三角洲序列可以划分出两个副层序。
There are three deltaic types developed in lacustrine strata,i.e.,normal,braid and fan deltas,which consist of delta plain,delta front and front delta.The continental strata are characterized by highly cyclic;therfore,the ideas and methods of sequence stratigraphy can be applied to lacustrine strata as long as base level is taken as sea level.In general,fan delta is well developed at the steep slope of faulted basin.Through the correlation of fan delta to standard deltaic parasequence model,a well developed fan delta succession could fall into two parasequences.\;
