Water-rock interaction demonstrates that, a gold-boring formation , i. e., a set of light metamorphic clastic gritstone, sandy slate, and tuffaceous slate in Wuqiang Runnel Formation, Ban Stream Group, act as the source of gold deposits in South-West Hunan. The gold is originally derived from volcanic eruption materials in Wuling-Xuefeng period; for the typical single gold deposit such as Mobin, which is short of sulphide, chlorine is very important in the metallogenic process; sulphur and chlorine perform as the major negative ions to form complex ions with Au throughout the gold activation and migration movement. The complex ion of chlorine and gold may keep stable in a wide range of temperature; the physical-chemical conditions in typical geothermal fluid system are of deciding significance for gold activation, migration and precipitation.

特定体系的水岩实验证实了漠滨及整个湘西南金矿的成矿元素Au和伴生元素主要源于赋矿围岩-板溪群五强溪组的一套浅变质碎屑砂岩、砂质板岩和凝灰质板岩；首次突破传统认识，证明氯在中低温热液体系中能与Au形成稳定络合物的形式进行运移，因此氯在本区Au成矿过程中起着相当重要的作用；成矿热液流体中Au主要以金硫、金氯络合物形式在溶液中迁移，阴离子∑S、Cl〓对金的活化、迁移及沉淀起主导作用，Au的伴生元素As、Sb在热液体系中与Au形成金锑、金砷络合物有利于金的进一步活化、迁移及沉淀；中低温热液流体成矿过程中，体系的物理化学参数对Au的活化、迁移及沉淀富集起决定性作用。

Soil quality is not high, for the sand and sandy loam.

土壤品质不高，为砂土和砂质壤土。

The oil shale of this area have four types, including mudstone, calcareous mudstone containing silty band, marlite and shale, and the former two are main types. The recoverable oil shale composed of 50% low-grade, 42% middle-grade and 8% highgrade oil shale. All of them are high-ash oil shale.

油页岩类型有泥岩、具粉砂质条带的含钙-钙质泥岩、泥灰岩和页岩4种类型，以前两者为主；低品级油页岩体积分数为50％，中品级油页岩体积分数为42％，高品级油页岩体积分数为8％，均属高灰分油页岩。

On the basis of plan form and crosscutting relationship of the faults, two kinds of tectonic systems were developed in Wu-Xia area, one was strike north-east, and another was strike east-west, the first was developed early and control the structural framework of Wu-Xia area, after that three times longitudinal compress action was happed. According to the intensity of tectonic deformation, The Wu-xia faulted zone from north to south can be divided into the thrust faulted belt, the fault fold belt and the monocline belt. from east to west have three regulatory faults, Wuerhe fault fold belt, Wuxia thrust faulted belt and Xiahong fault fold belt. Base on that 9 secondary structural unit can be divided.Structural accommodation zone and the distribution of reservoir strata have intimate business connection. Usually, Structural accommodation zone was the source zone of arenaceous sediment. The Wu-xia faulted zone have 3 kinds of structural accommodation, concordant approach, concordant overlap and concordant colinearity.

首先研究本区的构造特征，根据断裂的平面形态及相互切割关系，乌夏地区发育两种构造体系：北东向构造体系和近东西向构造体系，前者形成早，控制了该区的构造格局，晚期有3次近南北向挤压作用叠加；乌夏地区南北根据构造变形的强度不同分为冲断带、断褶带、单斜带，东西由于横向调节断层的存在分为乌尔禾断褶区、乌-夏冲断区和夏-红断褶区，进一步划分为九个次级单元；构造调节带与储集层的分布关系密切，通常是大量富砂质沉积的源区，乌夏地区发育三种类型的构造调节带：同向接近型、同向叠覆型和同向共线型。

In fact, the available sand is insufficient to form a continuous blanket overlying the unconformity

事实上，所补入的砂质物不足以在不整合面上形成连续的盖层。

In a quartz psamments with 3 ppm of P in Lencóis Paulista, Sao Paulo State, to evaluate the effects of thermophosphate, broadcasted and furrow applied, on the soil chemical properties and on the sugarcane production.

保利斯塔含有3毫克/公斤 P的石英砂质新生土上做了研究，评价热法磷酸盐撒施和沟施对土壤化学性质和甘蔗生产的影响。

Le Dracula is the main group for the ash, glaucum, purplish red basalt and andesite, fine-grained tuff, crystal-tuff debris, ash-tuff, tuffaceous siltstone, tuffaceous silty mudstone uneven beds, rocks folder jasper , Ansan porphyrite and long-sandstone and siltstone.

太勒古拉组主要为灰、灰绿、紫红色玄武岩、安山岩、细粒凝灰岩、晶屑沉凝灰岩、火山灰沉凝灰岩、凝灰质粉砂岩、凝灰质粉砂质泥岩不均匀互层，夹碧玉岩、安山玢岩及长石砂岩、粉砂岩。

Time domain reflectometry is widely used in determining water content for general agricultural soils.

试验通过往土壤中加入电介质溶液，以及在不同粘粒含量土壤上用时域反射仪测定土壤含水量，研究结果表明：在较低含水量情况下砂土 1 5cm3cm- 3，砂质壤土。

The split between the two groups can hardly be papered over.
