VHT exhibits higher tar yields across regions and coal facies, particularly in limnic settings
VHT shows higher f_al^H/f_a^s values, positively correlated with tar yield
VHT has lower condensation and branching (f_a, X_bp, C, BI)
VHT contains lighter small molecular compounds with higher main carbon number, lower ΣC21-/ΣC22+ ratio, and fewer aromatic rings
