Abstract X-ray computed tomography (CT) can reveal internal, three-dimensional details of objects in a non-destructive way and provide high-resolution, quantitative data the form CT numbers. The sensitivity number to changes material density means that it may be used identify lithology within cores sedimentary rocks. present pilot study confirms use Representative Elementary Volume (REV) quanti...

Winchcombe is a CM chondrite that fell in England on February 28, 2021. Its rapid retrieval was well characterized. Within two polished sections of Winchcombe, terrestrial phases were observed. Calcite and calcium sulfates found sample recovered from field March 6, 2021, halite observed months after its recovery driveway 2, These characterized by scanning electron microscopy, Raman spectroscopy...

Recent studies claiming to revive ancient microorganisms trapped in fluid inclusions in halite have warranted an investigation of long-term microbial persistence. While starvation-survival is widely reported for bacteria, it is less well known for halophilic archaea-microorganisms likely to be trapped in ancient salt crystals. To better understand microbial survival in fluid inclusions in ancie...

this paper presents a probabilistic optimal power flow (popf) algorithm considering different uncertainties in a smart grid. different uncertainties such as variation of nodal load, change in system configuration, measuring errors, forecasting errors, and etc. can be considered in the proposed algorithm. by increasing the penetration of the renewable energies in power systems, it is more essent...

The Mighan Playa is the largest playa in Markazi Province. Sedimentary and soil structures show that during all phases the playa was ephemeral. The duration and frequency of flooding varied causing variations in the relative amounts of accumulation, and soil formation. The clastic fraction of the playa sediment consists of quartz, mica and chlorite while the non-clastic evaporite fraction is do...

A new ichnogenus and ichnospecies of burrow, Katbergia carltonichnus, are described from Upper Permian and Lower Triassic rocks of the Karoo Basin, South Africa, where they are preserved in pedogenically modified overbank deposits that are interpreted as inceptisols subsequently gleysol overprinted. Sigmoidal burrows consist of a long (‡0.5 m) cylindrical tube, ranging from 1–2 cm in diameter, ...

We use 3D seismic reflection data from the Levant margin, offshore Lebanon to investigate structural evolution of Messinian evaporite sequence, and how intra-salt structure strain varies within a thick salt sheet during early-stage tectonics. Intra-Messinian reflectivity reveals lithological heterogeneity otherwise halite-dominated sequence. This leads rheological heterogeneity, with different ...
