Petrographical-geochemical characteristics and floral-faunal compositions of the Valia lignite deposits from Cambay Basin (Gujarat), western India
(Elsevier, 2021)Lignite-bearing sequence of the Valia mine, associated with the Cambay Shale Formation (early Eocene) in Cambay Basin of western Indian State Gujarat, has been studied. An integrated approach (including organic petrography, ... -
Petrography and chemistry of basalts from the Carlsberg ridge
(Geological Society of India, 1991)The petrography of the basalts collected in dredge hauls from the Carlsberg Ridge (3 degrees 37'N and 64 degrees 07'E) show systematic variations in their textural and mineralogical assemblages, from an outermost vitreous ... -
Petrography of basalts from the Carlsberg ridge
(CSIR-NISCAIR, 1989)Petrographic characteristics of basalts collected from a segment of the Carlsberg Ridge (lat. 3 degrees 35'N to 3 degrees 41'N; long. 64 degrees 05'E to 64 degrees 09'E) show typical pillow lava zonations with variable ... -
Petroleum - its present and future
(Indian Association for Limnology and Oceanography, 1985)World's "published proved" reserve of oil by the end of 1984 was known to be of the order of 95,000 million tonnes. Of this, 57% lies buried in the middle eastern countries. At the present rate of growth in consumption and ... -
Petroleum Hydrocarbon Catabolic Pathways as Targets for Metabolic Engineering Strategies for Enhanced Bioremediation of Crude-Oil-Contaminated Environments
(Multidisciplinary Digital Publishing Institute (MDPI), 2023)Anthropogenic activities and industrial effluents are the major sources of petroleum hydrocarbon contamination in different environments. Microbe-based remediation techniques are known to be effective, inexpensive, and ... -
Petroleum hydrocarbon concentration in sediments along northern west coast of India
(NISCAIR, New Delhi, 1991)Gas chromatography revealed that nonpolar material extracted from surface sediments collected along the northern west coast of India was originated from petroleum hydrocarbon residue. Petroleum hydrocarbon levels as ... -
Petroleum hydrocarbon concentration in selected species of fish and prawn form northwest coast of India
(CSIR-NISCAIR, 1994)Concentration of petroleum hydrocarbons in 6 fish and prawn species sampled at 10 transects from Veraval to Ratnagiri were determined using alkali digestion and alumina column chromatography followed by fluorescence ... -
Petroleum hydrocarbon concentration in surface sediments in continental shelf region along the central west coast of India
(Philippine Society of Sanitary Engineers, and the Asian Recycling Association, 1991)Gas chromatography revealed that nonpolar material extracted from surface sediments collected along the northern west coast of India was originated from petroleum hydrocarbon residue. Petroleum hydrocarbon levels as ... -
Petroleum hydrocarbon contamination along oil tanker routes in the Arabian Sea
(CSIR-NISCAIR, 1984)Concentration of petroleum hydrocarbons in seawater from the oil tanker route region between 0-25 N and 45-75 E were estimated using UV-absorbance and fluoroscence techniques. Concentrations in surface waters averaged 9.2 ... -
Petroleum hydrocarbon residues in the marine environment of Bassein-Mumbai
(Elsevier, 2004)The paper reports PHc contamination in water, sediment and biota of the coastal area of Bassein-Mumbai in relation to relatively less polluted sites (Dabhol and Ratnagiri, Maharashtra) off the west coast of India. To ... -
Petroleum hydrocarbons and trace metals in Visakhapatnam harbour and Kakinada Bay, east coast of India
(NISCAIR, CSIR, 1996)High concentrations of PHC were observed in the inner channels (viz. South lighter canal, Northern arm, North Western arm and Western arm) of Visakhapatnam Harbour, Andhra Pradesh, India. The estimation of trace metals ... -
Petroleum hydrocarbons in intertidal ecosystem along the Bombay Coast
(NISCAIR, CSIR, 1995)Petroleum hydrocarbon content in intertidal sediment and water samples collected at Madh, Worli and Colaba were in the ranges of 5.1-7, 5.8-7.4, 2.9-10.3 mu g.g sup(-1), wet wt and N.D.-18.5, N.D.-5.8 mu g.l sup(-1) ... -
Petroleum hydrocarbons in northwest coastal waters of India
(NISCAIR, New Delhi, 1993)Impact of domestic and industrial wastewaters on coastal waters was studiEd. by monitoring petroleum hydrocarbon concentration (PHC) up to 25 km distance from shore, along Okha-Ratnagiri Coast, Maharashtra, India during ... -
Petroleum hydrocarbons in some ports along the west coast of India

Petroleum hydrocarbons in surface sediments in Kandla creek (Gujarat)
(National Institute of Oceanography, Goa, 1987)Petroleum hydrocarbons in the surface sediments were determined gravimetrically and spectroscopically to evaluate petroleum oil pollution in the Kandla creek. They ranged from 9.6 — 140.5 and 6.5 — 23.3 μg g-1 (wet wt.) ... -
Petrological Characteristics and Genesis of the Central Indian Ocean Basin Basalts
(Geological Society of China, 2012)The Central Indian Ocean Basin (CIOB) basalts are plagioclase-rich, while olivine and pyroxene are very few. The analyses of 41 samples reveal high FeO sup(T) (approx. 10-18 wt percent) and TiO sub(2) (approx. 1.4-2.7 wt ... -
