n.前渊
The lithologic oil and gas reservoirs are developed in the foredeep depression zones and forebulge zones due to the cratonward pinching of strata. 前渊凹陷带主要发育有岩性油气藏，前缘隆起由于地层向克拉通方向尖灭，常形成岩性油气藏。
In the foredeep adjacent to the orogenic belt, the coarse gravel sediment in Yageliemu Formation marked the beginning of the thrusting. 在紧邻造山带的前渊带，亚格列木组砾质粗碎屑沉积体标志着逆冲推覆的重新开始；

A foreland basin system may be divided into four structural elements such as piedmont fold-thrust belt, foredeep depression belt, slope belt and frontal uplift belt. 在成藏研究中,前陆盆地可以划分为前陆褶皱冲断带、前渊坳陷带、斜坡带和前缘隆起带等4个结构单元。
A uncompensated oil generation sag formed when foredeep basin rapidly subsided,and back-bulge basin developed into a semi-restricted oil generation sag under the blockage of foreland uplift. 前渊盆地快速沉降过程中发育欠补偿生油凹陷，在前陆隆起阻挡作用下隆后盆地形成半局限环境生油凹陷。
