摘要

Utilizing Atomic Force Microscopy (AFM) to observe the surface structure of barkinite and vitrinite of “barkinite” liptobiolith in nanoscale, reveal the surface microstructures of barkinite and vitrinite, that is, the netlike structure of vitrinite maeromolecular clusters and the fiberlike, granular, and netlike structure of barkinite macromolecular clusters. With the increasing of maturity, the structure of barkinite maeromolecular clusters are fiberlike →granular →irregular netlike →netlike in sequence, while the structure of vitrinite macromolecular clusters change from loose, irregular network to highly orient arranged, regular network.
