Petrofacies Evolution of Bayana Basin Sandstones of Mesoproterozoic Delhi Supergroup, Bharatpur District, Rajasthan, Northwestern India

Monitoring of organochlorine pesticides in and around Keoladeo National Park, Bharatpur, Rajasthan, India.

Keoladeo National Park (KNP) is an important wintering ground for thousands of birds that undertake a perilous journey over the Himalaya to make a seasonal home in a wetland ecosystem. However, this wetland is now getting polluted by various types of contaminants such as pesticides because of the agricultural practices in the catchment area from where the park receives water. Keeping this in mi...

Prevalence of Vitamin D Deficiency among Healthy School Children in Jaipur District, Rajasthan, India

Vitamin D deficiency is one of the common nutritional deficiency and it exists in both childhood and adult life. The prevalence of vitamin D deficiency is 50-90 % in the Indian subcontinent. This was a cross sectional study which includes 96 apparently healthy school going children (50 Male & 46 Female) of age 5 to 10 years. We found that 33.33% (15 Male &17 Female) had vitamin D levels {25(OH)...

DIAGENESIS AND RESERVOIR QUALITY EVOLUTION OF SHELF-MARGIN SANDSTONES IN PEARL RIVER MOUTH BASIN, SOUTH CHINA SEA

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...

Apatite fission track age of Mesozoic sandstones from Beipiao basin, eastern China: Implications for basin provenance and tectonic evolution

The apatite fission track (FT) analysis of Jurassic sandstones from the Beipiao basin in the eastern China indicates a large variation in FT age peaks. The sandstone of the Beipiao Formation has two peak ages at 178.8 and 40.0 Ma, while the sandstone of the Tuchengzi Formation has three age peaks at 152.0, 77.5 and 32.5 Ma. This implies that the provenance of the Beipiao basin in the early Jura...
