Relationships between the pore size and coal facies parameters. (a) Micropores (<10 nm) versus TPI; (b) transition pores (10-100 nm) versus TPI; (c) mesopores (100-1000 nm) versus TPI; (d) macropores (>1000 nm) versus TPI; (e) Micropores versus GI; (f) transition pores versus GI; (g) mesopores versus GI; (h) macropores versus GI; (i) micropores versus GWI; (j) transition pores versus GWI; (k) mesopores versus GWI; (l) macropores versus GWI; (m) micropores versus VI; (n) transition pores versus VI; (o) mesopores versus VI; (p) macropores versus VI.
