Paleocene and  Lower Eocene deposits in SW Iran are known as Pabdeh formation.Pabdeh formation is one of the most important lithostratigraphy unit as source rock has been deposited in Zagros basin over an extremely long period in time. The area under research is the Ghachsaran 55 subsurface Section located  from the Ghachsaran oil field in Dezful embeyment in zagros fold zone. The Lower boundry...

background and objectives : zeolite is a group of anionic hydrated aluminosilicates with a tridimensional structure which has great implications in remediation of water, sediment and soil resources. the present research aims at physicochemical investigation, clay mineralogy and micromorphology of soils along rafsanjan-sarcheshmeh lithotoposequence, southeastern iran. materials and methods: the ...

A study of the diagenetic evolution of sandstones from Panyu low-uplift in the Pearl River Mouth Basin was carried out to unravel the controls on shelf margin sandstone reservoir quality. The reservoir rocks, Oligocene volcanic clastic sandstones of the Zhuhai Formation, have a burial depth of 2765 to 3440 m. 70 samples were studied using the granulometric analyses, X-ray diffraction (XRD) anal...

We present here results on the preservation of organics in highly oxidized rock materials and clay layers drilled from 0-6m-depth (Borehole-7) under the Mars Analog Rio Tinto Experiment (MARTE). This simulated a Mars robotic drilling mission at the RioTinto (Spain) [2,5]. The RT represents an important analog of the Sinus Meridiani Mars Site, and an ideal model for a potential deep subsurface M...

This paper describes part of the construction of a second theater in the underground museum complex, below the Gateway Arch in St Louis. Given the needs for relatively quiet, non-intrusive rock removal, and yet precise cutting within the museum complex a method of using low pressure (35 MPa) abrasive laden waterjets was developed for cutting the vertical walls of the theater down to a depth of ...

Clay rock in the Tamusu (TMS) area Inner Mongolia province is one candidate as a geological disposal site for highly radioactive waste China. The diffusion behavior of HTO and Se(IV) clay was studied by through-diffusion (TD) experiments numerical analysis to determine spatial temporal variation. A minimum error conducted coefficients compacted TMS clay. TD experimental results showed that Se r...

The migration of organic compounds in soils is a major concern several environmental issues. Contaminants display distinct behaviours as regards to their specific affinities towards constituents. retention mechanism hydrophobic by natural matter well known. ionizable mainly related oxides and clay minerals, even if less documented reductive media. In this work, we investigated the soft clay-ric...
