摘要：

Strontianite (SrCO3), witherite (BaCO3) and alstonite (CaBa[CO3](2)) were among the range of epigenetic coal cleat/fracture carbonates identified within the Wittingham Coal Measures, Jerrys Plains Subgroup in the Hunter Valley. Three stages of diagenetic cement development, all related to basin evolution, are postulated. Material for the development of the various carbonates was derived from: basinal pore fluids, surrounding rock and organic matrix as a result of diagenetic exchange, active mass transport or devolatilization of basement rocks during metamorphism, including plutonic intrusion.
