The level of nitrate concentration in groundwater is a measure of the degree of contamination of the environment. However, it says little about the origin of nitrates. Stable isotopes of N and O (δ15 N and δ18 O) can differentiate between manure and chemicalfertilizers. This is the reason for undertaking a study on groundwater with high concentration of nitrates in the national monitoring network to recognize the origin of nitrates. Contrary to expectations, the results suggest that nitrates are derived mostly from manures and less from chemical fertilizers. Further studies are urgently needed.

An issue of mean residence time (MRT) evaluation, i.e. the period of time from rainfall until drainage of groundwater by rivers (Danube River Basin, Vistula River Basin and Narew River Basin), is discussed Asimple method of evaluating the groundwater MRT for the Danube River Basin based on tritium data is introduced. It has been confirmed that the historical tritium level in the rivers, being higher than in precipitation, has its end and is reversed, opening a new pathway in understanding the surface-groundwater interaction and specifically in evaluating MRT of groundwater. The authors have defined a separate notification for mean residence time of the whole water in the basin (τ) and mean residence time for groundwater in the basin (τwp). Based on the tritium study the obtained τ values are 6.5 and 5.7 years for the Vistula River Basin (VRB) and the Narew River Basin (NRB), respectively. In turn, the obtained τwp values are 8.0 and 6.0 years, respectively. NRB is a lowland plain and a morphologically, geologically and hydrogeologically uniform basin. The obtained τ wp of groundwater is thus representative for the whole basin. Instead inmorphologically non uniform VRB basin groundwater τwp is a generalized value,i.e.averaged over contributed parts of the basin.

New biostratigraphical and carbon isotope data are presented for the Upper Jurassic limestones of the Raptawicka Turnia Limestone Formation (High Tatric unit, Western Tatra Mountains, Poland) from the Mały Giewont area. The Kimmeridgian, lower Tithonian and lower part of the upper Tithonian have been identified on the basis of calcareous dinocysts and calpionellids. Eight microfossil biozones are distinguished: acme Fibrata, acme Parvula, Moluccana, Borzai, Tithonica acme Pulla(?), Malmica, Chitinoidella and Crassicollaria (pars). The Kimmeridgian/Tithonian boundary is indicated at the top of the Borzai Zone 76 m above the base of the Raptawicka Turnia Limestone Formation. The microfossil stratigraphy suggests the late Early Kimmeridgian age (acme Parvula Zone) of the ammonites described by Passendorfer (1928). The taxon Taramelliceras ex gr. compsum found 14 m above those ammonites is Late Kimmeridgian in age. Seven microfacies types (MF) are identified in the Upper Jurassic limestones of the Mały Giewont area. The Bositra-Saccocomidae MF occurs across the Lower-Upper Kimmeridgian boundary. The planktonic and benthic foraminifera occur in the Upper Jurassic deposits of the Raptawicka Turnia Limestone Formation. The genera Lenticulina Lamarck and Spirillina Ehrenberg are common in the Kimmeridgian and Tithonian limestones. The palaeobathymetric evolution of the Kimmeridgian-Tithonian deposition recorded in the Mały Giewont sections reveals: the transgressive episode at the Lower/Upper Kimmeridgian boundary interval, the transgression peak during the Early Tithonian (Malmica Zone) and gradual shallowing of the High-Tatric swell in the Late Tithonian. Integrated isotope stratigraphy and biostratigraphy enabled correlation with the pelagic section of the Sub-Tatric succession in the Długa Valley section. The middle part of the Raptawicka Turnia Limestone Formation (Upper Kimmeridgian) might be correlated with the upper part of the Czajakowa Radiolarite Formation (red radiolarites) and Czorsztyn Formation in the Długa Valley section. The upper part of the Raptawicka Turnia Limestone Formation of Early Tithonian age corresponds mostly to the Jasenina Formation. The overall similarity of the δ13C decreasing values recorded in the Kimmeridgian–earliest Tithonian interval of the Mały Giewont (this study) and Długa Valley sections indicates that the generally shallow-water deposits of the Raptawicka Turnia Limestone Formation accumulated below the zone influenced by changes in the composition of marine water caused, for instance, by intense rainfalls.

The points of the national network of groundwater monitoring comprise a stable benchmarks in quality and quantity monitoring. The obtained data (tritium and δ18O) are important for understanding the groundwater cycling and are indirect indicators of aquifer vulnerability to anthropogenic pollution. The goal of this paper is to present the relation of the tritium content and delta value of stable isotopes of oxygen against the groundwater sampling depth in 2004–2012. It is demonstrated that the remains of “nuclear” tritium concentration is still present in groundwater as a tritium peak at depths around 30 m. Determination of dynamics of recharge in groundwater bodies, based on national network observation points is associated to the estimation of the groundwater residence time in aquifers and remains one the vital problem of hydrogeology.

The authors described micro-scale carbonate concretions occurring at a depth of about 41 m within Holocene sandy sediments filling the Guadiana River paleovalley, representing the transitional fluvial- -estuarine facies. Despite their minute sizes, the micro-concretions show a complex internal structure. Regular distribution of Mg, Mn and Ca can be assigned to a chemical zoning, pointing to precipitation under varying chemical conditions. Based on morphological and chemical peculiarities, four types of concretions can be distinguished. Detrital Fe-Mg-carbonates form nuclei. At first, Mn-rich carbonate precipitated as a coating, which is coherent with the sequence of precipitation of carbonates associated with bacteria-mediated oxidation of organic matter. Subsequently, the main bodies of concretions precipitated as Fe-carbonate (siderite). The last precipitation episode is marked by enrichment in Ca. The XRD patterns show the presence of a mixture of discrete carbonate phases.

Na podstawie interpretacji cech geochemicznych próbek granitów karkonoskiego i tatrzańskiego można przypuszczać, że granity te różnią się pod względem środowiska geotektonicznego. Magma, z której wywodzi się granit karkonoski, mogła pochodzić z górnych partii skorupy, natomiast magma tatrzańska - z dolnych. Na podstawie diagramów dyskryminacyjnych można sądzić, że granit tatrzański intrudował w reżimie subdukcyjnym, poprzedzającym kolizję płyt; można by go wiązać z magmatyzmem łuków wulkanicznych. Granit karkonoski przypuszczalnie reprezentuje magmatyzm postkolizyjny, późnoorogeniczny.

Geochemical data of granite samples allow to ascribe Karkonosze and Tatra massifs to different tectonic environments. One may suppose, that the parent magma of the Karkonosze granite derived from the upper part of the crust, whereas the parent magma of the Tatra granite from the lower one. The Tatra granite was emplaced before collision of plates in the subduction regime and could be related to the volcanic arc granites. The intrusion of the Karkonosze granite was post-collisional, late-orogenic.
