Joints within the Catskill Delta complex are believed to be natural hydraulic fractures and abundant indirect evidence supports this claim. The indirect evidence is based on many observations of joint surface morphology and joint spacing among other features. The Alleghanian orogeny left a unique imprint on the joint surfaces also, indicating a rotating horizontal compressive stress field. Nume...

Knowing the occurrence and distribution of soluble ionic salts allows us to model the aqueous history and geochemical conditions of surface solutions on Mars. Salts deposited as coatings are particularly important for attaining this knowledge because the thermal infrared (TIR) remote sensing method for determining mineral abundance is limited to the top few hundred micrometers of the surface. T...

Abstract Halite formations are attractive geothermal reservoirs due to their high heat conductivity, resulting in higher temperatures than other at similar depths. However, halite highly reactive with undersaturated water. An understanding of the geochemical reactions that occur within halite-saturated formation waters can inform decision making regarding well construction, prevention clogging,...

We develop an approach to utilize anisotropic metamaterials to solve one of the fundamental problems of modern plasmonics--parasitic scattering of surface waves into free-space modes, opening the road to truly two-dimensional plasmonic optics. We illustrate the developed formalism on the examples of plasmonic refractor and plasmonic crystal, and discuss limitations of the developed technique an...

Halophilic archaebacteria (Haloarchaea) can survive extreme desiccation, starvation and radiation, sometimes apparently for millions of years. Several of the strategies that are involved appear specific for Haloarchaea (for example, the formation of halomucin, survival in fluid inclusions of halite), and some are known from other prokaryotes (dwarfing of cells, reduction of ATP). Several newly-...

Irene Zhang started her presentation by explaining that checkpointing is similar to “suspend,” but while taking a checkpoint, the virtual machine can continue its execution. Because checkpointing is used for fault tolerance, taking a checkpoint can be done quickly, in less than a few seconds; restoring from the checkpoint, although slow, hasn’t been a problem; however, recent applications, such...

In the present study, the behavior of the different isotopes activity concentrations for three different rock samples (siltstone, shale and sandy dolomite) as well as in the different leachates of these rocks were studied at different time intervals, using a HP-Ge spectrometer. The activity concentration of U for the leachates gradually increases while that for U is nearly constant. The results...

Introduction: The search for life on Mars involves many potential strategies for the analysis in situ of surface samples or the analysis of returned samples in a controlled environment, in particular analyses seek evidence of tangible life and/or biomolecules. It is important to develop mineralogical standards suitable for testing the techniques that will be used for these analyses. Evaporites ...

The paper presents the results of laboratory studies on strength–strain properties shales representing four siltstone-claystone lithostratigraphic units occurring in Baltic Basin. Laboratory a triaxial stress state were conducted as single failure tests cylindrical samples oriented parallel and perpendicular to lamination within rocks. Mutually cut out from same drill core sections order determ...
