贵州息烽温泉控热推覆构造的发现及成因研究

根据近年来磷矿深部勘探资料,对贵州息烽温泉的构造地质条件及地热特征开展研究,获得了有关温泉地质成因的新认识。(1)由洋水背斜、安清断层(F₁)和温泉断层(F₂)组成的叠瓦状逆冲推覆构造体系,构成了息烽温泉地热水系统的主体及边界,该控热构造体系内地表构造与地腹构造并不统一,老地层盖在新地层上,构成顶、底两层叠置的多个热储单元,这些热储单元是地热水形成和运移的良好场所。(2)安清断层(F₁)使多个热储单元直接接触,从而具有密切的水力联系,为导水、导热的良好通道;温泉断层(F₂)构成了息烽温泉区地热水系统的边界。(3)大气降水沿断裂通道下渗至深部的碳酸盐岩热储层中,吸收热量形成地热水,在高温高压条件下,向洋水背斜核部进行迁移,受上覆寒武系碎屑岩盖层的保护和温泉断层的限制,形成洋水背斜西翼和北端的地热资源有利富集区,最后受分支断层阻挡而自然岀露。     

安徽省温泉旅游区的品牌建设与营销策略研究

安徽省温泉旅游区以它独有的特色和文化的魅力赢得社会广泛的关注,也吸引更多的人对温泉旅游区的品牌建设与营销策略的研究。阐述了安徽省温泉旅游资源赋存状况,并分析安徽省温泉旅游区的品牌建设与营销策略现状。得出如下主要结论:(1)安徽省温泉多数位于隆起的大别山区、长江沿岸的巢湖—和县一带以及皖南地区;(2)产品开发利用层次不一,大多处于中程度利用;(3)温泉相关的旅游区品牌建设与营销策略相对滞后。最后在此基础上,提出现阶段安徽省温泉旅游区的品牌建设与营销策略的对策。

A culture-dependent survey of thermophilic bacteria from hot springs in Xiamen area in China

Microbes are believed to play important roles in ecosystem function in many environments. The hot springs of Xiamen Island are close to the Xiamen Sea, and may have some characteristics different from those of inland hot springs. Microbes living in the hot springs of Xiamen may have new characteristics. However, little is known about microbial communities of hot springs close to the Xiamen Sea. A culturedependent survey of microbial population in the Xiamen hot springs was performed by using an approach combining total cellular protein profile identification and 16S rRNA gene sequencing. A total of 328 isolates of bacteria were obtained from liquid and sediment samples from the Xiamen hot springs, including neutrophilic thermophilic bacteria and moderately thermophilic acidophiles. Neutrophilic thermophilic bacteria, which grow at a temperature range of 55—90℃ including Rhodothermus marinus (Strain 1), Thermus thermophilus (Strain 2), Thermus thiopara (Strain 3), Geobacillus stearothermophilus (Strain 4), Geobacillus thermoleovorans (Strain 5), and Pseudomonas pseudoalcaligenes (Strain 6), were recovered by 2216E plates. Moderately thermophilic acidophiles, which can grow at temperatures above 50℃ and a pH range of 1.8—3.5 such as Alicyclobacillus acidoterrestris (Strain 8), Sulfobacillus acidophilus (Strain 9), and Sulfobacillus thermosulfidooxidans (Strain 10), were isolated on selective solid medium containing sulfur and Fe2+. Among these strains, Rhodothermus marinus, Thermus thermophilus and Geobacillus stearothermophilus are not only thermophiles, but also halophiles. One bacterium strain (Strain 6) shared 99% nucleotide sequence homology with Pseudomonas pseudoalcaligenes on the 16S rRNA gene sequence, but was quite different from Pseudomonas pseudoalcaligenes in biological characteristics, suggesting that it may represent a novel thermophilic species. Results indicated that various species of neutrophilic thermophiles and moderately thermophilic acidophiles were widely distributed in the Xiamen hot springs and that Rhodothermus marinus and Thermus thermophilus dominated the cultivable microbial community.     

山东温泉旅游资源分析及科学发展思考

山东省温泉资源分布广泛、储量大,利用历史十分悠久,在温泉资源开发应用过程中,应根据其分布、类型、开发利用现状,并结合国内外的科技成果而进行科学开发与综合利用,建设既有地方民俗文化特色又与国际接轨的可持续发展模式。     

2019年10月12日广西玉林北流MS 5.2地震深部孕震环境

地震是地壳或岩石圈构造变形的一种方式,施加于边界断层及其活动块体内的力决定了它们的变形方式(伸展、挤压、走滑),而变形(或地震)的空间分布受岩石圈流变学控制,尤其是受断层和其间块体强度以及这些块体与岩石圈耦合作用的控制( Thatcher,2009).而火山岩浆作为低粘度熔体,其活动通常也会产生地震,地震类型和大小与岩...     

青岛即墨温泉盆地热水沉积指示物及其标识性意义

经野外取样和XRD测试技术,在即墨温泉盆地发现硅质沉淀物、盐华、石膏、自然硫等温泉热水沉积指示物.根据热水沉积指示物的空间分布和含量的变化,阐述温泉热水沉积指示物的标识性意义：（1） 热水沉积指示物是划分第四纪沉积物层系的依据;（2） 是温泉地下热储温度的指示剂;（3） 依据热水沉积指示物百分含量的空间变化,可圈定温泉地热中心,指导地热资源开发;（4） 是寻找地下盲温泉和古地热水活动的标志;（5） 温泉热水沉积模式对现代海底热水沉积作用、成矿作用环境的模拟研究具有重要参考作用.     

临沂市温泉（井）成热机制分析及找热方向研究

临沂市地处鲁西隆起南部,地热资源丰富。该文介绍了临沂市的地层、岩浆岩、构造、地热背景、主要控热断裂及20余眼温泉(井)的情况和分布。通过分析汤头温泉、白塔地热井、汤坊崖地热井、铜井地热井、松山地热井、新村地热井、西高都地热井等主要温泉(井)的控热断裂、成热机制,认为该区地热主要分布在沂沭断裂带与NW向深大断裂交会处,地下水补给多沿NW—SE断裂,热源以深大断裂沟通深部热源,水温、水量较好地热井均处在沂沭断裂带沂水-汤头断裂以西的、控热断裂为张性断裂或的张扭性断裂凹陷区内。结合临沂市区域地质构造特点,认为蒙山断裂与鄌郚-葛沟断裂深部交会处,尼山断裂、峄城断裂与鄌郚-葛沟断裂交会处为地热勘探靶区。
