Hydrogeology and Hydrogeochemistry of the Lauria Mountains Northern Sector Groundwater Resources (Basilicata, Italy)

Geofluids (2019)

Filomena Canora Giovanna Rizzo Simona Panariello Francesco Sdao

In this study, the hydrogeological characterization of the northern sector of the Lauria Mounts carbonate hydrostructure (southern Apennines, Basilicata region) has been carried out and the hydrochemical properties of different collected groundwater samples have been characterized. Several normal springs drain the hydrostructure, some of them characterized by high annual mean discharges. Groundwater samples were collected from different springs; many parameters such as pH, electrical conductivity, and total dissolved solids have been measured, and major (cations and anions) elements and stable isotopes have been analysed following standard test procedures. Other chemical characteristics were derived from the analysed quality parameters. The results elucidate that the main hydrogeochemical processes control the chemical content and assess the quality of the groundwater within the hydrostructure. The analyses highlight that the chemical compositions of groundwater are strongly influenced by the lithology, especially limestones and dolomitic limestones; they explain and confirm the hydrogeological setting of the system. The groundwater system displays light different geochemical signatures. The processes contributing to the concentrations of major ions depend primarily on carbonate dissolution. The analysis, in all studied groundwater samples, shows that the facies groundwater type is Ca–HCO 3 , bicarbonate is the dominant anion, and calcium is the dominant cation with appreciable magnesium concentrations. To identify the aquifer’s recharge areas, the environmental stable isotopes oxygen and hydrogen, deuterium, and 18 O were analysed. The unaltered δ 18 O and δ D signatures for the groundwater of the major springs allows identifying the recharge area of these emergencies at elevations ranging from 900 m to 1000 m (a.s.l.), pointing out the presence of deeper flow regime feeding of these springs. The groundwater sample isotopic characteristics of D and 18 O suggest that most of the groundwater is recharged directly by infiltration in a high-permeability medium.

P-T estimates from amphibole and plagioclase pairs in metadolerite dykes of the Frido unit (southern Apennines-Italy) during the ocean-floor metamorphism

Giovanna Rizzo Filomena Canora Maria Carmela Dichicco Salvatore Laurita Maria T. Cristi Sansone

Abstract The metadolerite dykes from the Frido ophiolitic sequence reflect strain partitioning with textures evolving from magmatic intersertal/intergranular, blast-ophitic and incomplete metamorphic recrystallization. Amphibole and plagioclase are the main minerals in these rocks. Amphibole composition reflects both bulk compositional and P–T changes. Different Ti, IV Al values between the brown and green amphiboles clearly indicate genetic conditions of amphiboles developed in ocean-floor hydrothermal metamorphic conditions. The electron microprobe analysis showed that the assemblage developed during ocean-floor hydrothermal type metamorphism (M1) consists of two main amphibole varieties: a brown one, and green; instead during orogenic metamorphism (M2) developed a blue amphibole. The magmatic plagioclase is anorthite (PL1) and the metamorphic plagioclase are oligoclase (PL2), albite (PL3). The estimated P–T conditions are in favour of their metamorphism under ocean-floor hydrothermal type. The variety of amphibole compositions and the plagioclase found in the metadolerite dykes offers useful constraints to reconstruction of the correlated environmental conditions providing new insights on the oceanic metamorphic evolution of this orogenic sector of southern Apennines.

Hydrogeology and groundwater salinisation in the Ionian coastal plane of the Basilicata Region.

Giuseppe Spilotro Filomena Canora F. Caporale Gustavo Roberto dos Santos Leandro N. Vignola

The Ionian coastal plane of the Basilicata Region (South of Italy) is an environment unique for its geological history and for the subsequent geomorphological evolution. It is in fact the water front of a tectonic graben between the Appennines on the left and the foreland of the Murgian hills on the right, filled from Pliocene Age up to now from clastic sediments by a mostly regressive sea. These sediments have been also deeply eroded by five rivers, whose alluvial beds, in the last thirty kilometres from the sea outlets, have the depth in equilibrium with the most recent variation of the sea level. This very complex situation describes the hydrogeology of the coastal plane, where almost three typical aquifers alternate along the south to north coastal line. This environment has also been one of the most preferred since the Greek age, with numerous famous settlements getting from the fashioned Sybaris at the extreme south, through Siris, Metapontum, to Taras in the North. Exceptionally climatic conditions and abundant ground water resources made this area very requested, until the sea rise and the subsequent water table rise made it unhealthy. Land reclamation during the XX th century, quarries activities along alluvial beds and the building of eleven reservoirs on the five main rivers or in their basins, and finally, irrigation have deeply modified the hydrogeology of the coastal plane. The natural flow in the surface and underground estuarine water systems has been deeply reduced, whereas the artificial recharge in the groundwater of the marine terraces has been strongly increased. The present hydrogeological setting, with some local overexploitation, is responsible of almost three basic kinds of salinization, one of which is directly related to an incoming sea intrusion. The paper will deal with the results of two hydrogeological investigations, led from 1998 to 2002 by the LABIA of Unibas and the Regional Authority, with unpublished stratigraphic and geochemical surveys.

Effects of Anthropogenic Modification of Karst Soil Texture on the Water Balance of ''Alta Murgia'' (Apulia, Italy)

Sinkholes and the Engineering and Environmental Impacts of Karst (2005)

Filomena Canora Antonella Sciortino Giuseppe Spilotro A. Di Santo

The "Alta Murgia" region (Apulia, Southern Italy) is a karstic plateau, which constitutes the main recharge area of the Murgia karstic aquifer. The natural morphology of the plateau is defined by widespread surface karst features: karst, karren fields, layers of outcropping rock with discontinuous and thin soils. In general, these soils, relatively thin with sparse vegetation, are primarily used as pastures. Recently, agricultural activities have caused dramatic changes. In particular, ploughing and crushing of the karst surface has led to a conversion of the landscape to fields growing wheat and other crops. Stone clearing practice are carried out by means of the repeated grinding of the carbonate rocks with modern technologies, intensive use of bulldozers and machinery, besides destroying and removing rocks from the fields. Practically, the natural karstic soils were replaced with a layer of homogenous soil, useful for cultivation. This cultivated soil has increased the evapotranspiration and significantly reduced the infiltration thus affecting the water balance and the aquifer recharge. In the present study we analyze the impact of changes in soil texture and crop growth on the water balance in the "Alta Murgia" area by analyzing the features of the newly created soil. The characterization of the modified soil involved both field and laboratory measurements. The HYDRUS 2D model was used to simulate the infiltration process in the unsaturated zone. The objective of this paper is to elucidate the effect of stone removal by presenting a water balance for new soils. The simulations demonstrate that the available infiltration rate at the top layer varies from 60% of the overall amount of rainfall for the bare soil to only 25% in the presence of vegetation. Knowledge of the interactions between vegetation, soil and climate is essential to quantify the vadose zone hydrology and, hence the hydrogeology of the underlying karst system.
