ROLE OF STATIC LOAD (OVERBURDEN) PRESSURE IN COALIFICATION OF BITUMINOUS AND ANTHRACITIC COAL.

January 1, 1985

Tissue from a calcite concretion (coal ball) and attached coal of semianthracite rank from the Belgium Bouxharmont coal bed were analyzed separately by elemental chemical, **1**3C nuclear magnetic resonance, reflectance, and paleobotanical techniques to compare relative degrees of coalification. The results indicate that static load pressure has no perceptible effect on coalification up to and including a rank of semianthracite.
