A Gram-stain-negative, rod-shaped bacterial strain, JN53(T), was isolated from the surfaces of weathered rock (potassic trachyte) from Nanjing, Jiangsu Province, PR China. Strain JN53(T) grew optimally at 30 °C, pH 7.0. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain JN53(T) belonged to the genus Chitinophaga in the family Chitinophagaceae. It was most closely relat...

A Gram-stain-negative, aerobic, motile with one polar flagellum γ-proteobacterium, designated strain SBZ3-12(T), was isolated from surfaces of weathered potassic trachyte. Phylogenetic analysis of this strain based on 16S rRNA gene sequences showed that it was most closely related to Dyella japonica XD53(T) (97.9% 16S rRNA gene sequence similarity), Dyella terrae JS14-6(T) (97.7%), Dyella soli ...

A novel mineral-weathering bacterium was isolated from weathered rock (potassic trachyte) surfaces collected from Nanjing (Jiangsu, PR China). Cells of strain JN246(T) were Gram-stain-negative, rod-shaped and non-motile. Strain JN246(T) was aerobic, catalase- and oxidase-positive, and grew optimally at 28 °C and pH 7.0. On the basis of 16S rRNA gene sequence analysis, strain JN246(T) belonged t...

We invert gravity and magnetic anomalies for basement relief at the Harrat Rahat Volcanic Field (HRVF) purpose of evaluating its geothermal energy prospects. HRVF is dominated by basaltic scoria cones other volcanic rocks overlying Proterozoic basement. The area considered this study located within northern consists mainly alkali basalts with lesser amounts benmoreite, mugearite, hawaiite, trac...

Abstract Melt inclusions readily rupture and form gas bubbles during explosive volcanic eruptions, but their role as a source remains enigmatic. Here, we examined pumice texture generated by the instantaneous bursting of melt 946 CE Plinian eruption at Baekdusan. The burst produced non-sheared, super-vesicular (>80 vol.% voids) bubble pockets, occupying volume fractions 6–24% within Millenni...

Aimed target area is deeply buried, complex lithology, dual media, reservoir development degree controlled by a variety of factors, meanwhile, lateral thickness and lithofacies change rapidly, strata formation poor. Therefore, igneous rock has difficulty in predicting, since seismic complicated to track trace, attribute analysis hard determine the time window, inversion modeling requires sophis...

The Sanshui Basin is located at the northern continental margin of South China Sea and characterized by a rift basin. bimodal volcanic rocks in record early Cenozoic magmatic activity Block, but evolution that produced poorly understood. Clinopyroxenes provide an opportunity to investigate magma during ascent. In this work, we classified nine types clinopyroxene phenocrysts according compositio...
