Karst development and the distribution of karst drainage systems in Dejiang, Guizhou Province, China, 1983, Song Linhua, Zhang Yaoguang, Fang Jinfu, Gu Zhongxong,
The nature of karstification of two contrasting areas on the north Guizhou Plateau (south China) is shown to be controlled by structure, lithology, geomorphic history and tectonics, and causes significant differences to arise in the subsurface drainage systems of the areas.The Shaqi area lies in a syncline of Permo-Triassic limestones underlain by an insoluble sandy shale which forms the local base level. Karst landforms are strongly influenced by the presence of four erosion levels corresponding to four periods of rejuvenation of the drainage systems. Drainage is concentrated along the syncline axis, and one system (Naoshuiyan) has been pirating another (Lengshuiyan) by headward retreat. Cave passages are typically phreatic.The Dejiang Town area lies in an anticline of Cambrian dolomite and Ordovician limestone. Three large subsurface drainage systems have developed along parallel faults, and have typically vadose cross-sections

Karst Geomorphology and Subterranean Drainage in South Dushan, Guizhou Province, China, 1986, Song Linhua

Civil engineering difficulties in the karst of China, 1988, Waltham A. C. , Smart P. L. ,
Karst landscapes, developed by solutional erosion of massive limestones, are characterized by underground drainage and the development of closed depressions. In tropical areas, with high solution rates, long uninterrupted periods of erosion and a lack of glacial planation, the expansion and deepening of these closed depressions creates a rugged relief dominated by either conical hills or steeper-sided towers. The form of the cones and towers is a function of both the carbonate lithology and the erosional history; the towers develop only in massive, mechanically strong, compact limestones where erosional planation and tectonic uplift have kept pace over a long period of time (Smart et al 1986). These karst landscapes are characteristic of huge areas of southern China, largely in the provinces of Guangxi and Guizhou (Fig. 1) and the spectacular scenery of the limestone has often been represented in classical Chinese painting. They are now also becoming a major tourist attraction, with Guilin, in Guangxi, frequently visited by Westerners. These terrains do, however, pose serious difficulties to the civil engineer. Where relief is not great, or where rates of uplift have been low, corridors of flatter ground have often been created by lateral planation at the water table. These corridors may be lithologically or structurally controlled, and form obvious routes through the karst. Where the relief is higher and the regional water table is not intersected, coalescence of the depressions to form flatter ground is rare, and road and rail development is more problematic. In order to avoid excessive and ... This 250-word extract was created in the absence of an abstract

Karst Geomorphology and Environmental Implications in Guizhou, China, 1992, Zhang Yingjun Yang Mingde, He Caihua

This paper establishes statistical relationships describing the morphology of three contrasting drainage areas in the karst plateau of Guizhou. A landscape model proposed takes as its basis a two-tiered morphology: an upper tier of peaks and cols which maintains a dynamic equilibrium; and a lower tier defined by depression or valley bases which can evolve differentially in time and space. Thus equilibrium and evolutionary processes coexist in this type of karst landscape within the same timespan. The evlution of subcatchments is shown to be not necessarily the same as that of the total catchment because of tectonic factors

Four areas with different styles of fenglin (tower and cone karst) are investigated using morphometric techniques in the Shuicheng area of Guizhou Province. The karsts were formed in the Neogene and were uplifted during the Quaternary, to present elevations of about 1800 m. Measurements were made of the characteristics of 745 cones using maps and aerial photographs supplemented by field investigations. The karst cones are found to be of almost constant slope angle (45-degrees to 47-degrees) regardless of structure, but with a tendency for slightly lower slopes to occur where the carbonates have impure interbeds. Although generally symmetrical in plan, elongation of both cones and intervening depressions appears controlled by major elements of the structure and the general slope of the topography. Spatial analysis shows the cones to be relatively uniformly distributed in three of the four cases studied. Morphometric evidence points strongly to parallel slope evolution of cones. A model is offered of landscape evolution in which sequential development occurs through stages of karst-tableland with dolines to fencong-depression to fenglin-depression and finally to fenglin-plain. Geological control becomes less influential as this development proceeds, with the smaller and more widely spaced cones of the later stages becoming increasingly symmetrical in form

Gypsum karst in China., 1996, Cooper Anthony, Yaoru Lu
The Peoples Republic of China has the largest gypsum resources in the world and a long history of their exploitation. The gypsum deposits range in age from Pre-Cambrian to Quaternary and their genesis includes marine, lacustrine, thermal (volcanic and metasomatic), metamorphic and secondary deposits. The gypsum is commonly associated with other soluble rocks such as carbonates and salt. These geological conditions, regional climate differences and tectonic setting strongly influence the karstification process resulting in several karst types in China. Well developed gypsum palaeokarst and some modem gypsum karst is present in the Fengfeng Formation (Ordovician) gypsum of the Shanxi and Hebei Provinces. Collapse columns filled with breccia emanate upwards from this karst and affect the overlying coalfields causing difficult and hazardous mining conditions. Gypsum karst is also recorded in the middle Cambrian strata of Guizhou Province and the Triassic strata of Guizhou and Sichuan Provinces. Gypsum-salt lake karst has developed in the Pleistocene to Recent enclosed basin deposits within the Qinghai-Xizang (Tibet) Plateau.

A new genus and species of troglobitic Trechinae (Coleoptera, Carabidae) from southern China., 1996, Taglianti Augusto Vigna
Guizhaphaenops zorzini n.gen.n.sp. is described from Anjia Yan Cave, Shuicheng County, Guizhou (China). This highly specialized troglobite species is easily recognizable from the other cave dwelling Trechini from China for the main morphological external characters, but its true relationships remain uncertain, the male being still unknown. Similar in habitus to Cathaiaphaenops and to Sinotroglodytes, the new taxon is much more related to the latter, being dorsally glabrous and having the mentum fused with the submentum, with a deep oval fovea, but it differs in its elongated head, with incomplete frontal furrows and without posterior frontal setae.

A stepped karst unconformity as an Early Silurian rocky shoreline in Guizhou Province (South China), 1996, Jiayu R. , Johnson M. E. ,
There succeeded by marine strata, karst unconformities signify a former rocky coastline. Such relationships may help sort out relative sea-level changes and aspects of local geography controlling facies distribution. An exceptional example of an early Silurian karst shore is well exposed near the village of Wudang in central Guizhou Province, near the capital city of Guiyang in South China. Here the Lower Silurian Kaochaitien Formation oversteps 63 m of paleotopographic relief in limestones belonging to the Llanvirn Guniutan Formation and Caradoc to early Ashgill Huanghuachong Formation (Ordovician). The corresponding rise in sea level took place coeval with tectonic uplift, as confirmed by a regionally diachronous relationship in the Ordovician-Silurian boundary across a 250 km track from central to northern Guizhou Province. The change in sea level also fits with a global rise of sea level in late Aeronian (later Llandovery, early Silurian) time. Borings of the ichnofossil, Trypanites, are reported from the karst surface of the Huanghuachong Formation and Silurian strata hh sink holes in this unit over 5 m deep. The Silurian karst shoreline near Wudang is integrated with other regional data to construct a paleogeographic map covering the northern half of Guizhou Province

Be-7 distribution in surface soil of central Guizhou karst region and its erosion trace, 1996, Bai Zg, Wan Gj, Wang Cs, Wan X, Huang Rg, Santschi Ph, Baskaran M,
Soil erosion in karst region of south China is one of the major environmental problems. Beryllium-7, produced by energetic cosmic rags, has been used to trace the geochemical process of the soil erosion. The study has shown that Be-7 activity profiles present a decreasing logarithmic pattern with soil depth. The maximum permeable depth of Be-7 is 2-5mm in different seasons and locations, which is deeper in autumn than in spring, On the contrary, its apparent activity on boundary soil is higher in spring than in autumn. The Be-7 inventories in soil cores are higher in accumulative locations than in eroded one. Upper hills in the karst region are seriously eroded. Erosive intensity is higher in rainy periods than in dry ones. Influenced by the micromorphology and precipitation, the eroded particles accumulated in shallow basin after a short-distance transportation in winter and spring. However, in summer and autumn, they might be transported into drainage systems


China has the worlds largest proven gypsum (CaSO4.2H2O) resources in the world. The gypsum ranges from pre-Cambrian to Quaternary in age and occurs in varied geological environments. The rapid dissolution rate of gypsum means that gypsum karst development can be very fast, resulting in progressively worsening geohazards. This paper reviews the characteristics of the gypsum deposits and their associated geohazards in China.Three kinds of gypsum karst are discussed. These include karst in massive thick beds of gypsum, karst in thin-bedded gypsum and compound karst in gypsum and carbonate rocks. Some site-specific problems are also examined. In the Shanxi coalfield, breccia pipes, or collapse columns, caused by the dissolution of Ordovician gypsum, penetrate the overlying Carboniferous and Permian coal-bearing sequences resulting in difficult coal mining conditions. In Guizhou Province re-activated gypsum karst is associated with leakage of water through the gypsum from a reservoir. Remedial engineering works have been carried out, but leakage still occurs. Groundwater abstraction from gypsiferous sequences is also problematical. It can yield sulphate-polluted water and cause subsidence problems both through gypsum dissolution and groundwater drawdown.

Special speleothems in cement-grouting tunnels and their implications of the atmospheric CO2 sink, 1998, Liu Z. H. , He D. B. ,
Based on the analyses and comparisons of water chemistry, stable carbon isotopes and deposition rates of speleothems, the authors found that there are two kinds of speleothems in the tunnels at the Wujiangdu Dam site, Guizhou, China, namely the CO2-outgassing type and the CO2-absorbing type. The former is natural, as observed in general karst caves, and the product of karst processes under natural conditions. The latter, however, is special, resulting from the carbonation of a cement-grouting curtain and concrete. Due to the quick absorption of CO2 from the surrounding atmosphere, evidenced by the low CO2 content in the air and the high deposition rate of speleothems (as high as 10 cm/a) in the tunnels, the contribution of the carbonation process to the sink of CO2 in the atmosphere is important tin the order of magnitude of 10(8) tons c/a) and should be taken into consideration in the study of the global carbon cycle because of the use of cement on a worldwide scale
