原始盆地 meaning in English
primary basin
Examples
- By studying the lithologjcal and mineral parameters ( pebbled elastics percent ratio , clastic maturation index , heavy crop stability factor ) of mesozoic sedimentary strata , the result shows that the northern boundary of present basin is near to the boundary of original basin and the moving distance of elastics is short , but the southern boundary of present basin is far from the boundary of original basin and the moving distance of elastics is long . the fades of northern basin are mainly delta fades and the fades of middle and southern basin are lacustrine fades
通过对盆地中生代沉积地层中各种岩矿参数(碎屑岩含砾百分比、碎屑成熟度指数和重矿物稳定系数)分析和综合研究认为，今盆地北部距离原始盆地沉积边界较近，碎屑物搬运距离较短；南部距离盆地古沉积边界较远，沉积物搬运距离较远；中生代盆地北部主要为三角洲沉积相，中南部为湖泊相沉积。 - The research on the lithologjcal and mineral parameters and the sedimentary fades of different periods of mesozoic strata shows that the northern boundary of yanqi basin is almost the same , but great differences existed in the southwestern yanqi basin , that is , the sedimentary range of mesozoic original basin is more bigger than present basin
中生代地层各种岩矿参数和各时代沉积相研究表明，今焉耆盆地北部与原始沉积边界较为相近；西南和南部的边界今古差异较大，即在中生代原始盆地沉积范围要比今盆地范围要广。
