That sandstone caves is most natural sandstone caves are surface river-cut notches at the foot of rock cliffs, or left part way up the cliff due to later downcutting. this origin accounts for most of the caves once inhabited by the pueblo indians in the sandstone cliffs of the western usa. true caves do occur in sandstone and some of these appear to be at least partially of dissolutional origin. their existence probably reflects matrix leaching by ground water moving through zones of especially high primary porosity and permeability. though sandstones with a calcite matrix cement are more prone to such development, even siliceous cement, which has a very low solubility in water, may be removed during a sufficiently long time span. the sandstone caves of the sarisarinama plateau, venezuela may be a special case of this type of development. these include shafts 300m in diameter and 200m deep, and passages up to 500m long. they were probably cut in the quartz sandstone by underground streams, after early leaching of the cement by hydrothermal solutions, and the shafts have been modified by later collapse [9].?

Hydrochemical variations during flood pulses in the south-west China peak cluster karst: impacts of CaCO3-H2O-CO2 interactions, 2004, Liu Z. H. , Groves C. , Yuan D. X. , Meiman J. , Jiang G. H. , He S. Y. , Li Q. A. ,
High-resolution measurements of rainfall, water level, pH, conductivity, temperature and carbonate chemistry parameters of groundwater at two adjacent locations within the peak cluster karst of the Guilin Karst Experimental Site in Guangxi Province, China, were made with different types of multiparameter sonde. The data were stored using data loggers recording with 2 min or 15 min resolution. Waters from a large, perennial spring represent the exit for the aquifer's conduit flow, and a nearby well measures water in the conduit-adjacent, fractured media. During flood pulses, the pH of the conduit flow water rises as the conductivity falls. In contrast, and at the same time, the pH of groundwater in the fractures drops, as conductivity rises. As Ca2 and HCO3- were the dominant (>90%) ions, we developed linear relationships (both r(2) > 0.91) between conductivity and those ions, respectively, and in turn calculated variations in the calcite saturation index (SIc) and CO2 partial pressure (PCO2) of water during flood pulses. Results indicate that the PCO2 of fracture water during flood periods is higher than that at lower flows, and its SIc is lower. Simultaneously, PCO2 of conduit water during the flood period is lower than that at lower flows, and its SIc also is lower. From these results we conclude that at least two key processes are controlling hydrochemical variations during flood periods: (i) dilution by precipitation and (ii) water-rock-gas interactions. To explain hydrochemical variations in the fracture water, the water-rock-gas interactions may be more important. For example, during flood periods, soil gas with high CO2 concentrations dissolves in water and enters the fracture system, the water, which in turn has become more highly undersaturated, dissolves more limestone, and the conductivity increases. Dilution of rainfall is more important in controlling hydrochemical variations of conduit water, because rainfall with higher pH (in this area apparently owing to interaction with limestone dust in the lower atmosphere) and low conductivity travels through the conduit system rapidly. These results illustrate that to understand the hydrochemical variations in karst systems, considering only water-rock interactions is not sufficient, and the variable effects of CO2 on the system should be evaluated. Consideration of water-rock-gas interactions is thus a must in understanding variations in karst hydrochemistry. Copyright (C) 2004 John Wiley Sons, Ltd

A 6000-year high-resolution climatic record from a stalagmite in Xiangshui Cave, Guilin, China, 2004, Zhang Meiliang, Yuan Daoxian, Lin Yushi, Qin Jiaming, Bin Li, Cheng Hai, Edwards R. Lawrence,
Middle-to late-Holocene palaeoclimate change has been reconstructed at high resolution by the analysis of the carbon and oxygen isotopes from a thermal ionization mass spectrometric (TIMS) U/Th dated stalagmite from Xiangshui Cave, near Guilin, Guangxi Province, China. The carbon and oxygen isotopic records from the stalagmite suggest that changes in the Asian monsoon since the middle Holocene (6000 BP) can be divided into two periods: (1) an interval from 6000 to 3800 BP when a strong East Asian summer monsoon gradually weakened and climate was relatively warm and humid; (2) a cool period from 3800 to 373 BP when the East Asian summer monsoon was relatively weak and the winter monsoon was probably relatively strong. This cooler interval was interspersed with a number of short warm periods. A This interpretation is largely based upon the general increase in 6180 values of the stalagmite between 6000 and 3800 BP and shifts in 6180 about a relatively heavy mean value between 3800 and 373 BP. The 6000 to 3800 BP trend is probably associated with decrease in precipitation and temperature subsequent to the mid-Holocene climatic optimum

An integrated linear/non-linear flow model for the conduit-fissure-pore media in the karst triple void aquifer system, 2005, Cheng Jm, Chen Cx,
Most karstic aquifer media may be characterized as the triple-void media with highly-varied hydraulic properties, including matrix pore, fissure and conduit, in which liner flow may co-exist with non-linear flow. In this paper, an attempt is made to couple linear flow with non-linear flow in a single unified flow governing equations by introducing the concept of equivalent hydraulic conductivity (EHC) and deriving a general Darcy's law for various flow. The expression of EHC in the karst conduit and fissure are also derived. The procedures of numerical implementation are demonstrated via an ideal model and a case study of karst aquifer system in the Beishan Ore Formation area, Guangxi Autonomous Region, China

A summary report of the Tiankeng Investigation Project, hosted by Prof. Zhu Xuewen in China in 2005. This included an extremely successful field tour to tiankengs (giant collapse dolines) in the karst of Chongqing and Guangxi, and an indoor meeting in the Karst Research Institute in Guilin when the definition of a tiankeng was formalised.

Tiankengs in the karst of China, 2006, Zhu Xuewen, Chen Weihai
China has the most extensive and diversified karst terrains in the world and most of them are rich in caves and dolines. The cone karst (fengcong) and tower karst (fenglin) developed in the humid climate in southern China form the most distinctive karst landscapes. Tiankengs are giant dolines that are a feature in some areas of the cone karst. In recent years, more than fifty tiankengs have been discovered in the cone karst in southern China, notably in the provinces of Chongqing, Guangxi, Sichuan and Guizhou. Current research indicates that tiankengs develop in specific environments of geomorphology, geology and hydrogeology, and are therefore distinguished from normal karst dolines.

Environmental Reconstruction of Karst using a Honeysuckle species widely used in Traditional Chinese Medicine, 2006, Xie Yunqiu, Zhang Cheng, L Yong, Deng Zhenping
As in the deserts of Northwestern China, there is a need to reconstruct the fragile karst of Southwestern China using sustainable techniques that protect the environment and develop the economy. One means of achieving this is to plant species used in traditional Chinese herbal medicine. The characteristics of Honeysuckle used in traditional Chinese medicine, when produced on the Donggangling Formation at Nongla Village in Mashan County, in Guangxi Province of Southwestern China, match those of Honeysuckle grown in traditional production areas of China, and comply with the specification set for the Honeysuckle by the P.R. China Codex. Added properties of the Honeysuckle are the accumulation of phosphorus and potassium, in addition to the accumulation of elements such as calcium, magnesium, copper, zinc and so on. Further discussion considers extending the areas in which this Honeysuckle is currently grown, and its limitations in the karst region of Southwestern China where 60% - 70% of calcareous soil may be suitable for its cultivation.

Application of x-ray microanalytical techniques to preliminary geomorphological studies in the Jiang Zhou cave system, China, 2007, Dale, John And Tony Harrison.
The increasing availability of microanalytical techniques for the compositional analysis of rock and mineral samples provides an attractive supplement or alternative to traditional water chemistry for geomorphological studies by small caving expeditions overseas. The paper describes how x-ray diffraction (XRD) and energy dispersive x-ray (EDX) spectrometry were used to throw light on queries raised about the speleogenesis of the vast Jiang Zhou cave system, which was recently discovered and explored by three China Caves Project expeditions to Guangxi Province in southern China.
