Volcanic activity and distribution of igneous rock are controlled by the activity period and intensity of large, deep extension faults. Southern China was in an extensional tectonic environment in …
Based on the analysis of outcrop, seismic, logging and drilling data, combined with exploration practice, the characteristics, distribution, reservoir performance and gas-bearing …
We are committed to collecting data on major and trace elements, isotopes, and chronology of Chinese volcanic rocks, which will provide us with a thorough understanding of the spatial and …
In this study, based on the 3D seismic data from Chengdu-Jianyang Block, and the seismic reflection attributes and waveform characteristics, the spatial distribution of the pyroclastic flow …
To figure out gas enrichment laws in Permian volcanic rocks, Sichuan Basin, an association among reservoir-forming elements was explored to analyze forming modes and …
In the Chengdu–Jianyang area, the volcanic rocks are mainly of alkaline basic and ultrabasic types. The effusive facies dominated by volcaniclastic rocks does not develop due …
Permian volcanic rocks are widely distributed in the western Sichuan Basin (southwestern China), with a thickness of more than 200 m, and have great exploration potential. Among them, the volcaniclastic rocks in the …
Based on Nb/Y-Zr/TiO2 diagram for the classification of the altered volcanic rocks, the Nadi Kangri Formation samples all fall into the medium to acidic volcanic rock field (Figure …
Based on the analysis of outcrop, seismic, logging and drilling data, combined with exploration practice, the characteristics, distribution, reservoir performance and gas-bearing properties of...
Volcanic rock weathered profile reservoir spaces mainly include primary pores, secondary pores, and fractures. The main factors that determine weathered profile reservoirs are lithology (lithofacies), weathering and …
