TL;DR: In this article, the authors used fluorescence image analyzer (FIA), scanning electron microscopy (SEM), electron probe microanalyzer (EPMA), and laser-scanning confocal microscopy(LSCM) techniques to determine the types, characteristics, formation mechanisms and contributions to volcanic reservoirs of various devitrification pores in typical oil-bearing volcanic rocks.
TL;DR: In this paper, the petrologic and pore evolution characteristics of welded tuff in the Fengcheng Formation in the Wu-Xia area, Junggar Basin, are evaluated, and the genesis of vesicular welded tiles and the formation mechanism of vicles are analyzed.
