- In profile, the syncline is asymmetrical and called inclined fold. 在横剖面上,这个向斜构造看起来是不对称的,这种褶皱称为倾斜褶皱。
- The structure of predicting area is a broad,gentle syncline,together with Hushan syncline made up a comb fold. 预测区内构造为一宽缓向斜,与弧山向斜共同构成隔档式(梳状)褶皱。
- This zone has little folds includes kuangshan anticline, laiwu syncline and fangzhen syncline. 褶曲构造不甚发育,主要有矿山背料及其两翼的莱芜向斜和方下镇向斜。
- Anticline and syncline, geometrical elements of fold, description and recognition of fold in the field. 背斜和向斜、褶皱的几何要素、褶皱的描述和褶皱的野外描述。
- The syncline structure feature mainly controls the leading factors influenc ing the slope stability. 向斜构造特征主要控制影响边坡稳定的主导因素;
- The acting law of syncline structure on mechanical effect of structural plane isanalyzed in detail. 深入分析了向斜构造对结构面力学效应的控制作用规律。
- The area in the west of Daxingxi structure to Mingshan syncline hasn't been explored and drilled yet. 大兴西构造以西至名山向斜。
- Qiaotouhe syncline is one of the important coal-bearing syncline basin in Lianshao coalfield, Hunan. 桥头河向斜是涟邵煤田重要的含煤向斜盆地之一。
- Please note this syncline is of inclined axial plane which has the same dip direction as the limb with gentle dip angle. 请注意,这个向斜构造的轴面是倾斜的,轴面的倾向与具有较缓一翼岩层的倾向一致。
- But the dip angles of both limbs of the syncline look different, with one limb steeper than the other though they dip toward the opposite direction. 但是这个向斜构造的两翼岩层倾角看起来有差异,虽然两翼的岩层倾向相反,其中一翼倾角较之于另一翼要陡一些。
- After later Palaeozoic, this area was transformed into a paraplatform from" southeast Caledonian miogeo- syncline" by later Caledonian movement. 晚古生代始,转化为后加里东准地台。
- The result shows that this area is a typical reversal anticline structure with a syncline in the lower section and an anticline in the upper section. 该区为一典型的反转背斜构造,其下部为向斜构造,上部为背斜构造;下部生成油气,上、下均可储存油气;早期以岩性圈闭为主,晚期构造及岩性圈闭均较发育。
- Therefore, prospecting and exploitation of coalbed methane should be carried through seams in which lies in underlayer of syncline. 向斜下层渗透率和含气量较高,所以煤层气的勘探和开发应以向斜下层煤层为主要目的层进行。
- Please note this syncline is of inclined axial plane which has the same dip direction as the limb with gentle dip angle . 请注意,这个向斜构造的轴面是倾斜的,轴面的倾向与具有较缓一翼岩层的倾向一致。
