The results showed that groundwater iodine ranged from 1.51 to 1106μg/L, and 31.4% of the samples have iodine concentrations higher than 150μg/L. High iodine groundwater samples are mainly observed in the coastal area of Bohai sea, and well depths greater than 350 m. The results of iodine speciation analysis showed that groundwater iodide, iodate and organic iodine had the ranges of <0.025∼854μg/L, <0.035∼293μg/L and <10∼296μg/L, respectively, indicating that iodide is the dominant species of iodine in groundwater at NCP. Iodate is only observed in groundwater with Eh values higher than 0mV, suggesting that groundwater redox condition is the main factor controlling iodine speciation. The widespread sub-reducing/reducing condition and low affinity of iodide are the two main factors promoting the iodine enrichment in groundwater.</p></div>","PeriodicalId":101039,"journal":{"name":"Procedia Earth and Planetary Science","volume":"17 ","pages":"Pages 312-315"},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.proeps.2016.12.069","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79275667","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this well, we have collected 38 samples as rock fragments, in order to investigate hydrothermal alteration by x-ray diffraction and microscopical methods. In this geothermal area, the hydrothermal alteration mineralogy depends upon (i) temperature of geothermal system, (ii) pressure of the system, (iii) type of the rocks in reservoir, (iv) permeability of the reservoir rocks, (v) geochemical composition of the reservoir rocks and (vi) stability of the minerals of reservoir rocks. There is a close relationship between geothermal system and hydrothermal alteration. With respect to this relationship, the monitoring of geothermal systems can be ensured by the parameters such as temperatures and hydrothermal alteration zones providing that the hydrothermal alteration mineralogy has been investigated particularly.

During the burial compaction of mud, the pressure and temperature of strata increased with depth, in which some complex physical, chemical and biological reactions occurred. Meanwhile, a large amount of porewater, which interacts with microbes, organic matter and minerals in mud, would be discharged into adjacent aquifers. Numerous previous efforts by geologists have put forward some evidences, indicating that a portion of components (such as ions and nutrient) in groundwater are from muddy sediments. This paper provides a brief overview of efforts on different reactions in pore water in which environments change from oxidation to reduction and interfaces between the aquitard and the aquifer. Then, in the view of geological evolution, an idea is proposed that mud provided not only water but also material source for adjacent aquifer during its compaction and burial. In order to further understand the genesis of natural groundwater, especially natural inferior groundwater and brine, the diagenetic reaction and mineralization, water-rock interaction during the compaction of sediment should be considered, which will be of great significance in hydrogeology.</p></div>","PeriodicalId":101039,"journal":{"name":"Procedia Earth and Planetary Science","volume":"17 ","pages":"Pages 392-395"},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.proeps.2016.12.099","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78635143","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
