This major natural phenomenon is named “ coral reef lenticular freshwater ” , and its discovery has opened up a new field of water resource utilization 这一重大自然现象,被命名为“珊瑚岛礁淡水透镜体” ,开辟了水资源利用的新领域。
It is possible to form abnormal pressure in the fleet stratum because the fluid of sandstone can not be expelled effectively in the sandstone lens closed down by mudstone 在被泥岩封闭的砂岩透镜体中,砂岩中的流体无法有效排出,导致在较浅的深度就可能产生异常超压。
The strength of frozen soil will decrease obviously if it is thawed , especially when ice lens is abundant in it , which is the main cause of the mud pumping in subgrade as well as the instability of foundation in seasonal frozen ground regions 摘要冻土,特别是含冰透镜体的冻土解冻时,出现强度大幅度下降的弱化现象,这是季节冻土区内路基春季翻浆冒泥、地基失稳的重要原因。
Subordinate are plagioclase granite dike , layered tonalite , tonalitic conglomeration dispersed in amphibolite , ultramafic rock and metabasalt etc . . plenty of igneous accumulated banding were discovered in amphibolite from nujinshan and bujing area some residual clinopyroxene also were found in a few of sample 超镁铁岩多为构造透镜体分布于断裂带中,多蚀变为蛇纹石岩,在牛井山及布京一带已发现并圈定了9个岩体(块) 。
The non - structural gas reservoirs in ordos basin can be divided into 4 types , such as a reservoir of lithologic trap of sandstone lens , lithologic trap of differential diagenesis , overlying lithologic - formation trap and the reservoir related with weathering and uncomformity surface 摘要鄂尔多斯盆地非构造气藏可分为4类:砂岩透镜体岩性圈闭、差异成岩作用形成的岩性圈闭、上倾岩性地层圈闭、与风化壳和不整合面有关的岩性地层圈闭气藏。
According to paleo - geomorphology and depositional systems analysis , three kinds of forming models of subtle traps were built . they are fan - delta front - slope - sliding turbidity subtle traps n sub - fan near fault - stepping faults - turbidity subtle traps and fan - delta - furrow - sub - fan - sliding turbidity subtle traps 综合分析表明,临南洼陷具有有利的油气成藏条件,发育有上倾尖灭型隐蔽油气藏、透镜体隐蔽油气藏、断层-岩性隐蔽油气藏等隐蔽油气藏。
4 . the feature of linearity and ring structures shows that three structural lenses that are formed by the junction of four level i faults in alignment are helpful to the formation of ore - body . in longshujiao and longtouzhai lenes there are many intersectant east - north and west - north low level faults , so they are concentration place of ore - bodys 4 、从遥感线环构造特征上看,区内的四条主要东西向线性构造,是级控岩控矿线性构造,它们在走向上弧形交接形成三个构造透镜体,是成矿的有利部位。
Because during the sedimentation of the flood plain - estuary fades , the conditions of sea level rising , tidal regime , sediment supply and accommodation space were suitable for the development of a tidal ridge system , the sand lenses associated with this facies may represent tidal ridge formation in the incised valley 在河漫滩河口湾相沉积期问,由于海平面上升、潮流体系、沉积物供给和可容空间条件适合一个潮流沙脊体系的发育,其中的砂质透镜体可能代表了下切河谷内发育的潮流沙脊。
The cataclastic rocks appeared in the fault zone include structural lenticles , fault breccias , protocataclasite and cataclasite . the microscopical cataclastic deformation mechanisms involved are microcracking , frictional sliding and pressure - solution , but there might have had ductile deformation relating to dislocation sliding in feldspar and quartz of the plutons 断裂带内碎裂岩系列构造岩主要是碎裂化岩石(包括构造透镜体和构造角砾岩) 、初碎裂岩和碎裂岩,显微变形机制主要有破裂作用、摩擦滑动和压溶作用。
Many academicians researched their formation and accumulation mechanism and put forward manifold mechanisms , including the special mechanism of minority liquid molecular controlling the accumulation of lens reservoir by unknown gravitation , difference between liquid pressure compelling hydrocarbon to accumulate firstly in the lens reservoir , along cranny in the case of hydrocarbon replacing pore water in the lenticular body under capillary pressure , difference breakthrough employing hydrocarbon entering lens reservoir and so on 国内外学者提出了多种成藏机制,包括未知重力运动机制作用下,少数流体分子的个别特性控制透镜状砂岩油藏聚集;毛细管力作用下油气替换透镜体中的孔隙水;烃浓度差是油气向砂体运移的主要动力;流体压力差使油气首先沿着裂隙向砂岩透镜体中运移、聚集而成藏;差异突破作用使砂岩透镜体成藏等。
