The study of facies analysis and interpretation the depositional environment Lemat Formation located at Bukit Tiga Puluh aims to clarify problems found in Paleogene sediments South Sumatra Basin. A detailed fluvial has been carried out Lubuk Bernai track. number observations, profiling, measured stratigraphic section have out. stratigraphy area can be divided into 5 units from old young, namely...

-This paper based on crossplot and core data,analysis the Pu Xi oilfield ,Putao Hua oil layer ‘s conventional logging response characteristic.Based on the describe of the three cored wells, Putao Hua oil layer is mainly made up with siltstone, muddy siltstone, silty mudstone,. First normalized the well logging curves, elimination the influence of the nongeological factors to the well logging cu...

In this study porous alumina samples were prepared and then coated using the biomimetic coating technique using a five times Simulated Body Fluid (5.0SBF) as the growth solution. A coating was achieved after pre-treatment with concentrated acid. From elemental analysis, the coating contained calcium and phosphorous, but also sodium and chlorine. Halite was identified by XRD, a sodium chloride p...

The Merced Formation comprises a 2-km-thick shallow marine and non-marine succession that was deposited in a small transtensional basin along the San Andreas Fault during the late Pliocene to middle Pleistocene. The sediments dip between 10j and 80j to the northeast, and are locally disrupted by small faults. During tilting, the beds have been rotated into subparallelism with the San Andreas Fa...

Diagenetic models for silt-rich mudstone (siltstone) are less advanced than those sandstone and clay-rich mudstone. In addition, the influences of diagenetic processes on reservoir quality in siltstone formations poorly understood. Here we examine roles depositional facies, detrital composition, compositional evolution Lower Triassic Montney Formation, a prominent siltstone-dominated western Ca...

Reconstructing variations in the major element chemistry of seawater provides constraints on how the global carbon and sulfur cycles have changed over geological time, but archives for this information are rare. This work generates a new independent record of ancient seawater composition, in particular the relative abundance of Ca and SO4, through Ca isotope measurements in marine evaporites. E...

Based on geologic mapping, measured sections, and lithologic correlations, the local features of the upper and lower type areas of the Early Arikareean (30.8-20.6 million years ago) Sharps Formation are revised and correlated. The Sharps Formation above the basal Rockyford Member is divided into two members of distinct lithotypes. The upper 233 feet of massive siltstones and sandy siltstones is...

In contrast to the previous refinement from photographic data [Ferrari et al. (1955 ▶). Gazz. Chim. Ital.84, 169-174], the present redetermination of the title compound, caesium hexa-aqua-magnesium arsenate(V), revealed the Cs atom to be on Wyckoff position 4d instead of Wyckoff position 4b of space group F3m. The structure can be derived from the halite structure. The centres of the complex [M...
