聚焦离子束扫描电镜研究微体化石的微观孔隙结构
A Study into the Microscopic Pore Structure of Microfossils with Focused Ion Beam Scanning Electron Microscopy (FIB-SEM)
摘要
Abstract
Focused ion beam scanning electron microscopy(FIB-SEM) is a dual beam system which combines focused ion beam (FIB) and scanning electron microscopy (SEM) to cut samples and display real-time images at nanometer scale. This study observed several kinds of microfossils from the Lungmachi Formation (Llandovery, Silurian) with FIB-SEM. The results reveal that submicron-nano pores, which provide valid space for shale gas reservoirs, are well-developed in conodonts, chitinozoans and acritarchs. Disparities of micro-pores in different fossil groups shown in this study will help to explain the cause of organic pore heterogeneity in shales.关键词
