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

Abstract: 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 … Show more

“…Contact metamorphic rocks are intensively fractured through hydrothermal fracturing, increased brittleness, metasomatism, and cooling induced jointing [ Driesner , ; Ingebritsen et al , ] and exhibit a distinct brittleness contrast relative to the granite and the unaltered rock mass. Especially around young intrusions, permeability is enhanced [ Matter et al , ] and remnants may persist over Mio of years [ Achtziger‐Zupančič et al , ; Baudoin and Gay , ; Holland and Witthüser , ]. Marbles exhibit a steep slope due to high surficial permeabilities, probably resulting from (paleo) karst, and low permeabilities deeper underground, where dissolution of the otherwise low‐porosity rock is minimal.…”

“…Borehole images allow for fracture identification as well as quantitative analysis of their abundance and orientation. The presence of fractures does not uniquely correlate with hydraulic properties, as they may be filled or closed [e.g., Matter et al , 2006]. Both Slack Canyon and Umtanum members contain fractured intervals observed in FMI images (Figure 3), but hydraulic testing indicates they have extremely low permeability [ McGrail et al , 2009].…”

“…Shaef et al (21) show that dissolution and precipitation reactions in basalt samples tested under laboratory conditions can vary considerably, depending on the glass content and composition of the host minerals. Matter et al (22) suggest that fracture porosity and connectivity in the basalt aquifer influence the in situ rates, which will differ significantly from those measured in the laboratory. Carbonate precipitation may also reduce in situ porosity and permeability within basalt aquifers over time (6).…”
