Abstract:

To search and measure the major compositions of seep dolomite, samples were pressed into small particles in ethanol in a mortar and then transferred onto copper grids. Each grid sample was measured with a Thermo Scientific Talos F200S transmission electron microscope at 200 kV in Guangzhou Institute of Geochemistry, Chinese Academy of Sciences.
