粗砂岩

With the increasing of the rock detritus content, the uniaxial compressive strength and Young's modulus increase; the elastic strain energy index and bursting energy index of studied the rocks increase; the duration of failure decrease.

随着碎屑颗粒粒径的增大，即由砂质泥岩、粉砂岩向砂岩过渡，粗粒的粒柱状矿物逐渐增加，而细粒的片状矿物逐渐减少，岩石的强度和刚性增强，在集中应力作用下，弹性能指数增大，发生脆性破坏的可能性增大及破坏持续的时间变短也更猛烈，岩石的冲击倾向性增强。

All of the variational law of density, longitudinal wave velocity and tensile strength of gritstone after high temperature are studied.

对40块粗砂岩试件高温后的密度、纵波波速和抗拉强度变化规律进行了试验研究。

Her first taste of rock climbing was in 1988 at Yorkshires's famous gritstone outcrop, Almscliff. In 1999 she began climbing regularly, first indoors at the leeds Wall, then on the gritstone and limestone crags of Yorkshire and Derbyshire.

她的第一次攀岩经历开始于1988年在约克郡著名的粗砂岩—— Almscliff 。1999年她开始有规律的进行攀岩训练，从利兹的岩壁到约克郡和德比郡粗砂岩、石灰岩。

The results show that the density of gritstone is decreased gradually as the temperature increasing; so that it can be ignored; the longitudinal wave velocity is linearly decreased when the temperature increasing, and decrease rate of it follows the law of conic; R is one temperature point, which makes the law of tensile strength of gritstone after high temperature follows the law of parabola; and the maximal tensile strength appears when the operative temperature is R. After the temperature is higher than 700 ℃, tensile strength is small and change range is small when the temperature is increased.

结果表明，高温后粗砂岩的密度随试验温度的升高减小幅度很小，几乎可忽略不记；高温后试件中纵波波速的传播随温度升高基本呈线性降低，而减小率呈二次曲线规律变化；存在一个温度点R，使高温后试件的抗拉强度呈开口向下抛物线关系变化，且在R温度作用后试件抗拉强度达到最大；当试验温度大于700 ℃后，试件的抗拉强度变得很小，且当温度升高时变化幅度也很小。

In some way, the nature of the geochemical field shows that the deep fluid took part in the energy mineral reservoir formation and mineralization.2、 In zones with the strong tectonic activity and basement faults, the elements combination of petroleum is complex and the material from deep resource can be found in which. The character of elements geochemical and carbon isotope all show that there are deep fluid components in some Energy Minerals. The material source of the water accompanying with petroleum reservoir is complex, and which with multi-sources. The character of elements geochemical shows that the uranium of Dongsheng uran ore comes from the upper crust, the greyish-green gritstone and hoary kaolinised argillaceous siltstone is important for the formation of uranium deposits,and the grey gritstone is great potential to surveying uranium deposits .

基底断裂带和构造活动强的区域，原油中元素组合复杂，并含有深源物质；元素地球化学特征和同位素特征反映部分能源矿产中含有深部流体成分；盆地内油气藏伴生水的物质来源较为复杂，具有多源性；元素地球化学特征显示东胜铀矿的铀源主要来自上地壳，灰白色高岭土化泥质粉砂岩及灰绿色粗砂岩对铀矿的形成具有重要的意义，灰色粗砂岩具有良好的找矿潜力；元素地球化学特征还表明，黑岱沟煤及煤层夹矸中微量元素来源于上地壳。

The results show that the sandstone reservoirs with high porosity and permeability are mainly composed of coarse-grained lithic quartz sandstone and quartz sandstone with relatively well-preserved primary intergranular pores, relatively large median radius and average pore throat radius, and relatively low displacement pressure.

结果表明：组成高孔、渗储层的砂岩类型主要是粗粒的岩屑石英砂岩和石英砂岩，其较多地保存了原生粒间孔，具有较高的中值半径和平均喉道半径以及较低的排驱压力；高能环境下有利的沉积微相和成岩早期包壳状胶结物对原生粒间孔隙的保护作用是形成高孔、渗储层的基础条件。

Paleogene braided river delta and meandering river delta are well developed in Gudong area They are composed mainly of coarse clastic rocks such as conglomerate, pebbled sandstone and sandstone, and are the major types of sedimentary facies in the study area.

孤东地区古近纪辫状河三角洲及曲流河三角洲非常发育，主要由砾岩、含砾砂岩及砂岩等粗碎屑岩组成，是本区重要的沉积相类型。

The middle oil-member is characterized by medium-sized sandstone and pebbled sandstone, with fair sorting and subangular sphaericity. Rock types mainly were feldspar debris sandstone.

中油组主要沉积中砂岩和含砾中砂岩，粒度整体较粗，分选性较好，磨圆度以次棱角状为主，岩石类型为长石岩屑砂岩。

Numerous iron spherules have been found from coarse sandstone in the bottom of the Changzhougou Formation (1.8Ga) and silicified carbonate rock of the Dahongyu Formation (1.6Ga) of Proterozoic strata of the Ming Tombs District, Beijing.

北京十三陵中元古代常州沟组底部的粗砂岩(l.8Ga)和大红峪组硅化碳酸盐岩(1.6Ga)中都发现了众多铁质宇宙球粒。

Although same belongs to front delta facies zone, and the foregoing reasons, the north depositional system controlled areas sediment smaller grain size, mostly siltstone, shaly siltstone (or a variety of calcium-pelitic siltstone) and mudstone portfolio, and there are lots of ostracods in these lithology, some ostracods formed stratigraphy, and north-west of the lithology of depositional systems is correspondingly more coarse, coarse pebbly, coarse sandstone and fine sandstone, and so on.

虽然同属三角洲前缘相带，但由于前述原因，造成北部沉积体系控制的地区沉积物粒度较细，多为粉砂岩、泥质粉砂岩和泥岩组合，且上述各种岩性中介形虫含量特别多、还有部分成层介形虫；而西北沉积体系控制的沉积物的岩性则相应粗得多，甚至有很多井钻遇砾岩、含砾粗砂岩、粗砂岩等粒度较粗的岩性。
