This paper aims at determining the behavior of thermal water brought to surface and how this might impact reinjection wells and the rock during reinjection. The biggest problem is that reinjection wells are predisposed to choking. We searched for a method to examine this process, including a model for physico-chemical changes in the water—rock interaction. Two different samples of powdered rock (designated α and β) were analyzed using thermal water samples from production and reinjection wells. The pH shows significant differences between the samples from wells where free water treatment was carried out, and those from the aerated thermal waters, as well as for the rock sample. Basically, a decrease in sediment volume can be obtained by increasing the pH. The salt effect was more coherent. Its result was an interesting case of W-shaped graphs from the producing well. On the other hand there is virtually no difference between the samples with acid titration.
本文旨在确定地表热水的行为,以及这对回注井和回注过程中的岩石的影响。最大的问题是回注井容易发生堵塞。我们寻找一种方法来检验这一过程,包括水岩相互作用的物理化学变化模型。利用生产井和回注井的热水样品对两种不同的粉末状岩石样品(α和β)进行了分析。自由水处理井样品的pH值与曝气热水样品的pH值以及岩石样品的pH值存在显著差异。基本上,通过增加ph值可以获得沉积物体积的减少。盐的作用更加连贯。其结果是一个有趣的产井w形图。另一方面,酸滴定的样品之间几乎没有差异。

Stone masonry arch bridges in North Hungary represent cultural heritage values. For the maintenance and preservation of these bridges detailed mapping of lithologies and weathering forms are required. The purpose of this paper is to present the identified lithotypes, their conditions (weathering grade) and their petrophysical properties by using in situ lithological mapping, documentation of weathering forms, non-destructive tests and laboratory analyses. Furthermore these analyses demonstrate the difficulties of characterization and diagnostics of the historical construction materials. Additionally the results of condition assessments and the properties of the four different dimension stones from four different sites provide examples for the large dissimilarities regarding the strength parameters. The above-listed parameters are required as input data for stability calculations and modeling of these structures.
北匈牙利的石砌拱桥代表了文化遗产的价值。为了维护和保存这些桥梁,需要详细绘制岩性和风化形式的地图。本文的目的是通过原位岩性填图、风化形式记录、无损试验和实验室分析,介绍已确定的岩性类型、风化条件(风化等级)和岩石物理性质。此外,这些分析表明了历史建筑材料的表征和诊断的困难。此外,四个不同地点的四种不同尺寸的石头的状态评估结果和性质为强度参数的巨大差异提供了例子。上述参数需要作为这些结构的稳定性计算和建模的输入数据。

One of the most important ores for REE mineralization are iron oxide–apatite (IOA) deposits. The Posht-e-Badam Block (PBB) is a part of the Central Iranian geostructural zone which is the host of most important Fe deposits of Iran. Exploration studies of the IOA deposits within the PBB (e.g. Esphordi, Gazestan, Zarigan, Lak-e-Siah, Sechahoun, Chahgaz, Mishdovan, Cheshmeh Firouzi and Shekarab) demonstrate that these deposits contain high contents of REE. Concentrations of ΣREE in the most important IOA deposits of the PBB include the following: the Esphordi deposit varies between 1.2 and 1.88%, the Gazestan deposit between 0.17 and 1.57%, the Zarigan deposit between 0.5 and 1.2% and the Lak-e-Siah deposit varies between 0.45 and 1.36%. Concentrations of ΣREE within the apatite crystals present within the IOA ores in the Esphordi, Lak-e-Siah and Homeijan deposits have ranges between 1.9–2.54%, 1.9–2.16% and of 2.55%, respectively.

Interaction between a Late Miocene andesitic dyke swarm and wet sediment in the Szoros Valley, Eastern Borsod Basin, Northeast Hungary 匈牙利东北部Borsod盆地东部Szoros河谷晚中新世安山岩岩脉群与湿沉积的相互作用

Magma/wet sediment interaction (e.g. autobrecciation, magma-sediment mingling, hyaloclastite and peperite-forming, etc.) is a common phenomenon, where hot magma intrudes into unconsolidated or poorly consolidated water saturated sediment. In the Eastern Borsod Basin (NE-Hungary) relatively small (2–30 m) subvolcanic bodies, sills and dykes with contact lithofacies zones were found generated by mechanical stress and quenching of the magma, and interacting with unconsolidated wet andesitic lapilli-tuff and tuff-breccia. Close to the contact between sediment and intrusions, thermal and mechanical effects may occur in the host sediment. Hydrothermal alteration and stratification of the host sediment were developed only locally along the contact zone, probably due to the paleo-hydrogeologic and paleo-rheological inhomogeneities of the lapilli-tuff–tuff-breccia deposits. Processes of magma/wet sediment interaction may be difficult to recognize because of limited exposure and/or certain similarities of the brecc...
岩浆/湿沉积物相互作用(如自角化作用、岩浆-沉积物混合作用、透明碎屑岩和橄榄岩形成等)是一种常见的现象,热岩浆侵入未固结或不固结的水饱和沉积物。在Borsod盆地东部(匈牙利东北部),发现了相对较小的(2 ~ 30 m)次火山岩、岩墙和接触岩相带,它们是由岩浆的机械应力和淬灭作用形成的,并与松散的湿安山岩蓝砾-凝灰岩和凝灰岩-角砾岩相互作用。在靠近沉积物与侵入体接触的地方,宿主沉积物中可能发生热效应和力学效应。热液蚀变和寄主沉积物分层作用仅沿接触带局部发育,这可能是由于珠光-凝灰岩-凝灰岩-角砾岩沉积的古水文地质和古流变学不均匀性所致。岩浆/湿沉积物相互作用的过程可能难以识别,因为有限的暴露和/或角砾岩的某些相似性。

The Ecse-halom is a burial mound (kurgan) in the Hortobagy region of Hungary. Built in the Late Copper Age/Early Bronze Age by nomadic people from the east, it now stands on the border between two modern settlements. A road of medieval origin runs along this border and cuts deeply into the body of the mound. The southern half of the mound was plowed and used as a rice field, and later a military observation tower was built on top of it. Despite this disturbance, the surface of the mound is in decent condition and provides a home for regionally significant, species-rich loess steppe vegetation. The mound comprises two construction layers as indicated by magnetic susceptibility and thin-section micro-morphological analysis. Examination of organic compounds and carbonate content at various levels showed different values, which suggest a variety of natural and anthropogenic stratigraphic layers. Mid-sized siltstone fraction is dominant in the section. The layers originate from the immediate vicinity of the mound, but have different characteristics than present-day soils. These mounds contain a valuable record of cultural and environmental conditions occurring at the time of their construction, and also serve as a refuge for ancient loess vegetation; therefore their conservation is highly recommended.
Ecse-halom是匈牙利Hortobagy地区的一个墓地(kurgan)。它建于铜器时代晚期/青铜时代早期,由来自东方的游牧民族建造,现在位于两个现代定居点的边界上。一条起源于中世纪的道路沿着这条边界延伸,深深切入土丘的主体。土丘的南半部被犁过,用作稻田,后来在上面建造了一座军事瞭望塔。尽管受到这种干扰,但土丘的表面状况良好,为具有区域意义的、物种丰富的黄土草原植被提供了家园。通过磁化率和薄层微形貌分析可知,土墩由两层结构组成。不同水平的有机化合物和碳酸盐含量测定值不同,表明存在多种自然和人为地层。剖面中以中型粉砂岩组分为主。这些土层起源于土丘附近,但与现在的土壤具有不同的特征。这些土丘包含了它们建造时发生的文化和环境条件的宝贵记录,也是古黄土植被的避难所;因此,强烈建议保护它们。

Non-luminescent nature of the planar deformation features in shocked quartz from the Ries impact structure, Germany: A new interpretation 来自德国里斯撞击构造的冲击石英的平面变形特征的非发光性质:一种新的解释

Quartz grains from the Ries impact structure containing shock-induced microstructures were investigated using Scanning Electron Microscopy in cathodoluminescence (SEM-CL), secondary electron (SEM-SE) and back-scattered electron (SEM-BSE) modes as well as Mott–Seitz analysis. The purpose of this study is to evaluate the mechanism by which CL detects Planar Deformation Features (PDFs) in quartz, which is one of the most important indicators of shock metamorphism in rock-forming minerals. PDFs are micron-scale features not easily identified using optical microscopy or scanning electron microscopy. The CL spectrum of PDFs in quartz that has suffered relatively high shock pressure shows no or a relatively weak emission band at around 385 nm, whereas an emission band with a maximum near 650 nm is observed independent of shock pressure. Thus, the ~385 nm intensity in shocked quartz demonstrates a tendency to decrease with increasing shock metamorphic stage, whereas the 650 nm band remains fairly constant. The re...

A coupled groundwater flow and heat transport model was developed for a trans-boundary geothermal reservoir located in the Alpokalja area. The study area lies in the western part of the Pannonian Basin, at the border between Hungary and Austria. The study area contains several famous geothermal water utilizations on both sides of the border, which has an impact on natural groundwater conditions. The aim of the modeling study was to evaluate the natural-state and production-state groundwater conditions, and to make predictions on cross-boundary interferences. A three-dimensional finite element-type coupled geothermal model was constructed to provide a coherent quantitative representation of geothermal flow systems. The model described the hydraulic behavior of the flow system, the interaction between different reservoirs, and geothermal conditions.

The Euganean Geothermal Field (EGF) is the most important thermal field in northern Italy. It is located in the alluvial plain of the Veneto Region where approximately 17*106 m3 of thermal water with temperatures of 60–86 °C are exploited annually. A regional-scale conceptual model of the Euganean Geothermal System is proposed in this paper using the available hydrogeologic, geochemical and structural data for both the EGF and central Veneto. The thermal water is of meteoric origin and infiltrates approximately 80 km to the north of the EGF in the Veneto Prealps. The water flows to the south in a Mesozoic limestone and dolomite reservoir reaching a depth of approximately 3,000 m and a temperature of approximately 100 °C due to the normal geothermal gradient. The regional Schio-Vicenza fault system and its highly permeable damage zone act as a preferential path for fluid migration in the subsurface. In the EGF area, a geologic structure formed by the interaction of different segments of the fault system in...
欧洲地热田(EGF)是意大利北部最重要的地热田。它位于威尼托地区的冲积平原,每年开采约17*106立方米的热水,温度为60-86°C。本文利用欧洲地热系统和威尼托中部的水文地质、地球化学和构造数据,提出了一个区域尺度的欧洲地热系统概念模型。热水来自于大气,渗透到EGF北部约80公里的威尼托普里阿尔卑斯地区。水在一个中生代石灰岩和白云岩储层中向南流动,深度约为3000米,由于正常的地热梯度,温度约为100°C。区域性斯基奥-维琴察断裂系统及其高渗透破坏带是流体在地下运移的优先通道。在EGF地区,由断裂系统的不同段相互作用而形成的地质构造。

A regional-scale conceptual model of the Euganean Geothermal System is proposed in this paper using the available hydrogeologic, geochemical and structural data for both the EGF and central Veneto. The thermal water is of meteoric origin and infiltrates approximately 80 km to the north of the EGF in the Veneto Prealps. The water flows to the south in a Mesozoic limestone and dolomite reservoir reaching a depth of approximately 3,000 m and a temperature of approximately 100 °C due to the normal geothermal gradient.

The Triassic karstic aquifer is the system with the greatest potential for the utilization of thermal waters in Serbia. As an integral part of the Dinaric tectonic unit, the Triassic aquifer extends widely over the western part of the Serbian territory and is characterized by cold waters. In contrast, the same but confined type of aquifer overlain by thick Tertiary sediments in the Pannonian Basin has significant geothermal potential. The major potential for tapping geothermal flow is in the southern and southwestern parts of the Pannonian Basin (Srem) and in the adjacent areas of Macva and Semberija in the Sava tectonic graben. In these areas the Triassic karstic aquifer has been tapped by several boreholes with depths ranging from 400 m to 2400 m. The temperature of the hottest water exceeds 75 °C, while maximal discharge is 40 l/s. Although the prospect of wider utilization of geothermal energy undoubtedly exists, some Serbian national plans count on a limited contribution of geothermal energy in renew...
三叠纪岩溶含水层是塞尔维亚利用热水潜力最大的含水层。三叠纪含水层是第纳里亚构造单元的组成部分,在塞尔维亚西部领土上广泛延伸,以冷水为特征。而潘诺尼亚盆地上覆厚第三纪沉积物的相同但密闭的含水层具有显著的地热潜力。开发地热流的主要潜力在潘诺尼亚盆地(Srem)的南部和西南部以及萨瓦构造地堑的Macva和Semberija邻近地区。在这些地区,三叠纪岩溶含水层已经被几个深度从400米到2400米不等的钻孔挖掘。最高温水温度超过75℃,最大流量40 l/s。虽然更广泛地利用地热能的前景无疑是存在的,但是一些塞尔维亚国家计划指望地热能在再生方面的有限贡献。
