Description: The uniform light gray material is vitrinite showing a well-developed remnant cell structure. The cells here are filled with much darker resinite. Compare the cell fillings here with the cell fillings in frames MA1 and MA3. The darker tone here indicates resinite. This is confirmed in frame MA 10 which is the same field in blue-light illumination.
