1.The slumping event deposits were mainly breccia dolostone (limestone) while the turbidity current event deposits were turbidity grain limestone (dolostone).
其中滑塌事件的沉积产物主要为滑塌角砾白云岩(石灰岩),浊流事件的沉积产物主要为浊积颗粒石灰岩(白云岩)。
2.Combined with such as the seismic, well-logging data, core, FMI imaging logging data, the paper evaluates the reservoir of Ordovician in Ka 1 block, and designates tow type reservoir rock: dolomite, limestone and four type reservoir:dissolution-void reservoir, dispersive fracture reservoir, fracture-void reservoir, vertical fracture reservoir. Thereinto, dolomite of middle-lower Ordovician reveals be mostly fracture reservoir, limestone of upper Ordovician reveals be mostly dissolution reservoir.
卡1区块的主要储集岩为石灰岩与白云岩,储层主要有四种类型:溶蚀-孔洞型储层、分散溶洞型储层、裂缝—孔洞型储层、高角度裂缝型储层,中下奥陶统白云岩主要为溶蚀型储层,而上奥陶统石灰岩则主要发育裂缝型储层。
3.Because of the serious disturbance, water stress has become the limiting factor of economic development in limestone districts. The paper aims at the experiment of Cajanus cajan.
石灰岩地区由于人为干扰,植被退化严重,水土流失加剧,强烈的水分流失己成为石灰岩地区经济发展的限制因子。
4.Limestone cliffs; limestone walls.

5.The properties and influence factors of dolomite limestone-water glass grout were studied. Results show that its cohesion is low and flowability and stability are good, setting time can be controlled from 5 hours to 20 hours,calculus strength and mortar strength can reach 1-3 MPa, and the primary influence factors include liquid/solid ratio or the Baume degrees of water glass, curing temperature and humidity, size of limestone grains and different technique process.
研究了白云质石灰岩—水玻璃灌浆材料的性能和影响因素 ,结果表明 :这种灌浆材料粘度较小 ,流动性好 ,可实现单液灌浆 ,凝固时间在 5~ 2 0h可调节 ,稳定性好 ,结石体强度和固砂强度达 1~ 3MPa。 液固比或水玻璃浓度、养护温度和湿度、石灰岩颗粒细度、不同工艺路线是影响浆材性能的主要因素。
6.An area of irregular limestone in which erosion has produced fissures, sinkholes, underground streams, and caverns.
喀斯特由于腐蚀而产生裂隙,落水洞,潜流和洞穴的不规则的石灰岩地区
7.West Guangxi Limestone Region includes wide areas of north tropics, south subtropics and middle sub-tropics, where the richness and uniqueness of biodiversity and cultural diversity are unparalleled not only in China but also in the world.
摘要广西西部石灰岩地区包括北热带、南亚热带和中亚热带的广阔范围,生物多样性和文化多样性的丰富性和独特性不仅在中国,而且在世界上都称得上是一个独一无二的区域。
8.Navassa, its enormous limestone cliffs rising straight out of the sea, is the oldest continuous overseas possession of the United States, older than Guantanamo, the Virgin Islands, Hawaii, and Alaska.
纳弗沙岛上巨大的石灰岩悬崖耸立海面上,是美国在海外持续拥有的最古老岛屿,比关达那摩、维京岛、夏威夷和阿拉斯加还要古老。
9.A list of endemic species distributed in limestone region on Hainan is tabulated.
