“…The topographical position between the two boreholes differs, with LDEO-2 located on the flank of a valley and LDEO-3 on a local high. Both boreholes penetrate most of the section of the Palisades sill and several tens of meters into the Newark Basin sediments (Burgdorff and Goldberg 2001). Based on drill chips, hand samples and thin sections, as well as geophysical logs, Burgdorff and Goldberg (2001) and Goldberg and Burgdorff (2005) characterize the petrophysical and lithological profile at this site (Figs.…”

“…Van Houten (1969) notes that the original argillite of the Lockatong Formation has been converted into black hornfels by contact metamorphism. The sandy inter-layers have been altered Burgdorff and Goldberg (2001) to a lesser degree (Merguerian and Sanders 1995). These authors note further that the igneous-sedimentary interface is crosscut by "dikes" of sandstone that intruded into the chilled and fractured dolerite during cooling, which are comprised of an aphanitic to glassy texture that becomes gradually coarser with increasing distance from the contact zone.…”

“…Figures 2 and 3 also illustrate the complexity of the contact zone between the dolerite and the underlying sedimentary rocks. The difference in the sediment sequences between LDEO-2 and LDEO-3 is attributed to the irregular intrusion path of the sill, crosscutting the sediment stratigraphy (Burgdorff and Goldberg 2001). The contact zone with an approximate thickness of 10-20 m includes the chilled dolerite and the meta-sedimentary rocks (Fig.…”

“…The geological and petrophysical characteristics of these formations have been investigated previously in numerous studies (e.g. Walker 1969;Olsen 1980;Schlische and Olsen 1990;Burgdorff and Goldberg 2001;Goldberg and Burgdorff 2005). The primary motivation for this study was the evaluation of the hydrogeologic properties of fractured intrusive and sedimentary rocks within their structural context.…”

Contact zone permeability at intrusion boundaries: new results from hydraulic testing and geophysical logging in the Newark Rift Basin, New York, USA

Hydraulic tests and geophysical logging performed in the Palisades sill and the underlying sedimentary rocks in the NE part of the Newark Rift Basin, New York, USA, confirm that the particular transmissive zones are localized within the dolerite-sedimentary rock contact zone and within a narrow interval below this contact zone that is characterized by the occurrence of small layers of chilled dolerite. Transmissivity values determined from fluid injection, aquifer testing, and flowmeter measurements generally fall in the range of 8.1E-08 to 9.95E-06 m 2 /s and correspond to various scales of investigation. The analysis of acoustic and optical BHTV images reveals two primary fracture sets within the dolerite and the sedimentary rocks-subhorizontal fractures, intersected by subvertical ones. Despite being highly fractured either with subhorizontal, subvertical or both fracture populations, the dolerite above and the sedimentary rocks below the contact zone and the zone with the layers of chilled dolerite are significantly less conductive. The distribution of the particular conductive intervals is not a function of the two dominant fracture populations or their density but rather of the intrusion path of the sill. The intrusion caused thermal fracturing and cracking of both formations, resulting in higher permeability along the contact zone. Malgré des zones très fracturées, caractérisées par l'une ou l'autre voir les deux lots de fractures, la conductivité hydraulique est assez faible. La distribution des intervalles particulièrement conductifs n'est pas une fonction des deux lots de fractures dominants, ou de leur densité, mais plutôt du taux de pénétration des couches. L'intrusion provoque la fracturation thermique des deux formations, induisant une conductivité hydraulique meilleure le long de la zone de contact. Résumé Des tests hydrauliques et des sondages géophysiques réalisés dans la formation Palisades et les ResumenPruebas hidráulicas y levantamientos geofísicos realizados en el manto interestratificado Palisades y las rocas sedimentarias subyacentes en la parte NE de la cuenca extensional Newark confirman que las zonas transmisivas particulares se localizan dentro de una zona de contacto dolerita-roca sedimentaria y dentro de un intervalo angosto por debajo de esta zona de contacto que se caracteriza por la ocurrencia de pequeñas capas de dolerita enfriada. Los valores de transmisividad determinados a partir de inyección de fluidos, pruebas de acuíferos, y estimaciones de mediciones de flujo generalmente caen en el rango de 8.1×10−8 y 9.95×10 −6 m 2 /s y corresponden a varias escalas de investigación. El análisis de imágenes BHTVópticas y acústicas revela dos conjuntos de fractura primarios dentro de la dolerita y las rocas sedimentarias: fracturas subhorizontales intersectadas por fracturas verticales. A pesar de encontrase altamente fracturadas ya sea con fracturas subverticals o subhorizontales o con ambas poblaciones de fracturas, la dolerita que se encuentra por encima, las rocas sedimentar...

a b s t r a c tGeologic carbon sequestration has the potential to reduce greenhouse gas concentrations in the atmosphere. However, one barrier to large scale implementation is concern for water quality degradation from leakage of high CO 2 fluids into drinking water aquifers. The hydrogeochemical response to simulated CO 2 leakage was studied to estimate major and trace element release and to develop criteria for water quality monitoring and risk assessment. In this study, approximately 3100 L aquifer water enhanced with 1 atmosphere pressure CO 2 gas was injected into a fracture zone located at 362-366 m below the ground surface in a sandstone/siltstone/mudstone interbedded aquifer in the Newark Basin. This was followed by a 3-6 week long incubation and then continuous monitoring of the hydrogeochemistry in the pumped-back water samples. Relative to background conditions, the recovered aquifer water displayed a decrease of pH, increase of alkalinity, Ca, Mg and Si concentrations, decrease of sulfate and Mo concentrations, and increased concentrations of trace elements including Fe, Mn, Cr, Co, Ni, Cu, Zn, Rb, Sr, Ba and U. These changes in aquifer water geochemistry can be explained by (a) dissolution of silicate and carbonate minerals and (b) trace element release that appear to be dependent on pH and pCO 2 and affected by the altered redox conditions in the aquifer. Rapid and simultaneous changes of pH, specific conductance, major and trace metal release in aquifer water could be used as indicators of CO 2 leakage from geologic sequestration sites. Hydrogeochemical parameters including pH, total dissolved solids and trace elements, particularly Fe, Mn, and Zn, need to be monitored in compliance with the U.S. Environmental Protection Agency (EPA) drinking water regulations. (Q. Yang). upward migration of stored CO 2 through faults, fractures, poorly sealed or abandoned wells into shallow drinking water aquifers (Keating et al., 2013) have led to the slow process of public acceptance and the delay of wide applications of carbon capture and storage (CCS) (Bachu, 2008). The increased acidity from CO 2 intrusion into freshwater and altered aquifer redox conditions could enhance the dissolution of carbonate and silicate minerals, and increase the dissolved concentrations of trace elements (Kharaka et al.
