Calcite straw stalactites growing from concrete structures (pp4-10) (PDF 1.2MB)     

by Garry K SMITH.
In this paper, the term 'calthemite' is used to encompass the various concrete-, mortar- or lime-derived secondary deposits consisting primarily of calcium carbonate (CaCO3) that grow from man-made alkaline structures outside the cave environment. Calthemites are very similar in composition and form to speleothems in limestone caves, but in concrete-derived straws carbon dioxide (CO2) is a reactant as opposed to a product. The growth rates and corresponding drip rates of four stalactite straws growing beneath a concrete building were recorded over a ten month period. The major influencing factors determining calcite deposition were the supply continuity of leachate and the drip rate. Growth rates up to two millimetres per day were recorded. Minute calcite rafts were observed and photographed on the solution drop surface. Sporadic movement of rafts around the drop surface (induced by air movement), is identified as affecting straw diameter and wall thickness. Deposition of CaCO3 straws derived from concrete is usually associated with hyperalkaline solution (pH > 9) as opposed to the near neutral pH to mildly alkaline solutions (pH 7.5–8.5) that commonly deposit speleothems.
This study was first presented at the 30th Biennial Conference of the Australian Speleological Federation Inc.,21–26 June 2015, Exmouth, Western Australia.

Tufa deposits at Inchrory and Glen Suie, Moray, Scotland (pp17-20) (PDF 1.3MB)     

by Trevor FAULKNER and Vanessa BRAZIER.
This observational article discusses the environmental history of the previously-reported large inactive spring-line tufa deposit at Inchrory in Moray, Scotland. An active cascade tufa deposit that is forming in the adjacent Marl Burn and other local or possible tufa deposits are also reported, together with previously unrecorded cascade tufa deposits in Glen Suie.
Classification: paper.

Maze caves of the Northern Pennines, UK (pp21-36) (PDF 3.3MB)     

by Tony HARRISON.
Maze caves have been known for many years in the Yoredale Group limestones of the Northern Pennines. There are at least 9 network maze caves with plan lengths exceeding 1km and having more than 10 loops, all but one accessed only via redundant mine levels. Two are currently inaccessible due to mine collapses. All are remote from modern surface features such as active or inactive watercourses, have a common lithostratigraphical setting, and display morphologies characteristic of caves formed by a transverse hypogenic speleogenetic process. The present study indicates that this mode of speleogenesis is a widespread regional phenomenon throughout much of the Northern Pennines. It is suggested that the formation of these caves has been assisted by an enhanced aggressiveness in the dissolving waters because of the nearby presence of mineral veins containing galena and other sulphide minerals (potential sources of sulphuric acid), although other sources of aggressiveness related to the rise of deep fluids cannot be dismissed. A number of smaller mazes or networks in the Northern Pennines may also have hypogenic origins, but others appear to be epigenic floodwater mazes. All network maze caves in the region are characterized by dominant systematic joint sets, normal to the bedding and near vertical, with typical trends of northwest–southeast, north–south, and westsouthwest–eastnortheast.

The hydrology of an ephemerally flooded doline: Pwll-y-Felin, South Wales, UK (pp41-47) (PDF 13.0MB)   Open Access  

by Gareth FARR, Owen NAUGHTON, Sivachidambaram SADASIVAM, Rhian KENDALL, Jonathan SAVILLE and Alan BOWRING.
The first annual hydrograph from an ephemerally-flooded doline in the UK is described. Flood duration and volume were characterised by combining water-level data with a detailed topographic survey. Rapid surface runoff of Na–SO4-type water is derived from a localized topographic catchment. The inflow stream produced a 'flashy' hydrograph with maximum flood depths reaching 7m when the doline can contain 7,383 m3 of water. Flooding occurred over 161 of the 365 day study period, with an average flood depth of 2.4m. Stage dependent drainage properties suggested that water loss is greater when the flood depth is >3m, indicating that there may be additional drainage conduits at higher levels within the doline. A conservative estimate of 138 ML year is provided for net loss of water to the underlying aquifer. The vegetation shows some zonation potentially related to flood duration, with higher diversity in the marginal zone subject to the greatest fluctuation in water levels. The classification of Pwll-y-Felin and other small ephemeral karstic water bodies should be considered not only as geological landforms but as small karstic dependant wetlands. Under-recording of small, isolated temporary water bodies is of concern to international conservation bodies. The methodology presented can help to characterize the hydrology of ephemerally flooded dolines and could be used better to understand karst dependent habitats, recharge in karst aquifers, water budget calculations and to improve management and regulation in karst aquifers.
