Dissolved sulphate δ
34
S and the origin of sulphate in coal mine waters; NE England
Coal mine waters have been sampled during a reconnaissance study in the East Midlands, South Yorkshire and Tyneside areas of England. Almost all the mine waters had similar δ
18
O and δ
2
H indicating a derivation from Holocene recharge (average -7.9‰ and -54‰, respectively, excluding two outliers). Most mine waters emerging by shallow gravity drainage have dissolved sulphate δ
34
S of < +10‰, suggesting a derivation of sulphate from oxidation of pyrite. Deeper mine waters, pumped from boreholes or shafts tended to be more saline with a dissolved sulphate δ
34
S of >+14‰ and, in two cases, >+30‰. The sulphate in these latter waters cannot be readily explained as deriving from pyrite oxidation. Alternative hypotheses (evaporitic or marine brines, evaporite dissolution, closed-system microbial sulphate reduction) can be invoked as explanations. A more general hypothesis proposes that deep groundwaters / mine waters can be regarded as saline “sinks”, whose sulphate δ
34
S is controlled by a dynamic equilibrium between rates of sulphate mobilisation from various sources and sulphate removal by precipitation or microbial reduction.

期刊介绍:
Quarterly Journal of Engineering Geology and Hydrogeology is owned by the Geological Society of London and published by the Geological Society Publishing House.
Quarterly Journal of Engineering Geology & Hydrogeology (QJEGH) is an established peer reviewed international journal featuring papers on geology as applied to civil engineering mining practice and water resources. Papers are invited from, and about, all areas of the world on engineering geology and hydrogeology topics. This includes but is not limited to: applied geophysics, engineering geomorphology, environmental geology, hydrogeology, groundwater quality, ground source heat, contaminated land, waste management, land use planning, geotechnics, rock mechanics, geomaterials and geological hazards.
The journal publishes the prestigious Glossop and Ineson lectures, research papers, case studies, review articles, technical notes, photographic features, thematic sets, discussion papers, editorial opinion and book reviews.
