“…The solubility of minerals such as quartz, chalcedony, and α-cristobalite is a function of temperature (Pasvanoglu et al., 2012). The changes in pressure and salinity have little effect on the solubility of quartz and amorphous silicon below 300°C, so the concentrations can be directly used as a geothermometer.…”

The aim of this work is to determine the thermal storage temperature of a deep thermal reservoir, which has a great significance for the effective utilization of geothermal resources. The temperature of the reservoir was estimated by the cation ratio geothermometer and SiO2 geothermometer methods. The results indicate that the K–Mg geothermometer is the best method of the cation ratio methods, with the calculated temperature of 108°C. The average value calculated by the SiO2 method was 107°C. The measured temperature of the GRY1 drilling water sample in the Cangxian arch belt was 108°C. Because the calculated results of the geothermometers were consistent with the measured value of the borehole water, the K–Mg and SiO2 geothermometers are suitable for the estimation of deep heat storage temperatures.

“…Sinkholes have also been observed appearing in thermal springs, as in Turkey, where at the Kozakli geothermal field a sinkhole some 30 m across and 15 m deep developed in January 2007 [42]. This means that dissolution can occur even at high temperatures, which has implications in a warming planet.…”

This review considers the current literature on sinkhole formation and occurrence. It incorporates several examples from around the world in order to gain a broader geographical scope on the problem. Challenges associated with sinkholes center around atmospheric acidification (pollution) and the formation of dissolution sinkholes. In addition, urbanization and its imposed changes on surface drainage as well as aquifer contamination also bear upon this geohazard. Solutions have been grasped through the deployment of geophysical techniques, in particular GPR. Engineering solutions are presented and critically discussed. Preventative planning based on early detection (through geophysical, GIS and multivariate analysis plus modeling, and possibly remote sensing techniques) are among the most effective available solutions. More research is needed to investigate the effects of increasing surface temperatures and interactions (synergies) with pollution.

“…Ground deformations entail sometimes the creation of surface-near tensile fractures and fissures in the surrounding [41], which offer new pathways for gas and water circulation. Pasvanoğlu et al [42] even report formation of an extensive sinkhole as a consequence of intense hydrothermal water abstraction in a karst regime at the Kozakli geothermal field in Turkey. As another extreme, reinjection triggered ground inflation in some cases [43].…”
