Abstract 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… Expand
Geochemical features of the geothermal CO2-watercarbonate rock system and analysis on its CO2 sources
Taking Huanglong Ravine and Kangding, Sichuan, and Xiage, Zhongdian, Yunnan, as examples, the authors summarize the hydrogeochemical and carbon stable isotopic features of the geothermalExpand
Unusual morphologies and the occurrence of pseudomorphs after ikaite (CaCO3 · 6H2O) in fast growing, hyperalkaline speleothems
Abstract Unusual speleothems, associated with hyperalkaline (pH > 12) groundwaters have formed within a shallow, abandoned railway tunnel at Peak Dale, Derbyshire, UK. The hyperalkaline groundwatersExpand
Calcite straw stalactites growing from concrete structures
In this paper, the term ‘calthemite’ is used to encompass the various concrete-, mortaror lime-derived secondary deposits consisting primarily of calcium carbonate (CaCO3) that grow from manmadeExpand
C and O stable isotopic signatures of fast-growing dripstones on alkaline substrates: reflection of growth mechanism, carbonate sources and environmental conditions
TLDR
Secondary carbonate precipitates (dripstones) formed on concrete surfaces in four different environments – Mediterranean and continental open-space and indoor environments (inside a building and in a karstic cave) – were studied and showed a strong positive correlation. Expand

TLDR
A scanning electron microscopy study of macroscopic manifestations of neoformations detected during an extensive visual survey of several modern architectural works in urban areas of northern and central Portugal suggests that cementitious materials play an important role as a source of pollutants for the most common neoformation such as carbonate rich stains and coatings.
