Vibracoring is a subsurface sediment acquisition (sediment coring) technique (Pierce and Howard, 1969; Howard and Frey, 1975; dreher et al., 2008) that returns sediment preserved within its stratigraphic and sedimentologic context. This process (see appendix 1) generates a continuous, contiguous sediment sample at a point by vibrating an aluminum core barrel vertically into the sediment (fig. 1...

Abstract Weathering of silicate rocks at a planetary surface can draw down CO 2 from the atmosphere for eventual burial and long-term storage in interior. This process is thought to provide essential negative feedback carbonate-silicate cycle (carbon cycle) maintain clement climates on Earth potentially similar temperate exoplanets. We implement thermodynamics determine weathering rates as func...

On April 23, 2019, a meteorite fall occurred in Aguas Zarcas, Costa Rica. According to the Meteoritical Bulletin, Zarcas is brecciated CM2 chondrite dominated by two lithologies. Our X-ray computed tomography (XCT) results show many different In this paper, we describe petrographic and mineralogical investigation of five lithologies meteorite. The bulk oxygen isotope compositions some were also...

to identify critical sediment sources in large catchments, using easily available terrain information at a regionalscale, a methodology was developed to obtain a qualitative assessment necessary for environmental management.fargas et al method was employed in the research. the study was carried out in one of the sub-basins of hableh roodbasin called dehnamak in the arid and semiarid climate of ...
