The Edinburgh Geological Society rewards excellence in geology and supports young people working in geology through a number of awards:

  •  The Clough Medal

  •  The Clough Memorial Award

  •  Grants from the Clough and Mykura Funds


The Clough Medal - list of Clough Medallists

This is the Society's premier award.  It is awarded annually to a geologist whose original work has materially increased the knowledge of the geology of Scotland and/or the north of England, or who is Scottish by birth or by adoption and residence and has significantly advanced the knowledge of any aspect of geology.
 

The Clough Memorial Award - list of Clough Award winners

The Clough Memorial Award is a monetary award, given to a geologist of British nationality and up to 35 years old whose research on some aspect of the geology of Scotland or the north of England is considered as having outstanding merit.  It is awarded biennially in even years.
 

The Clough and Mykura Funds

Grants from these funds, normally of the order of a few hundred pounds, are available to support geological field work at home or abroad. Grants from the Clough Fund may be awarded for fieldwork or other geological enterprise in any area, provided that a suitable Scottish connection can be demonstrated through the recipient or their institution, or through the work itself. Grants from the Mykura Fund are restricted to geological fieldwork in Scotland, with preference given to workers under 35 years old. Applications are invited from professional and non-professional geologists and from students of geology, and each will be considered on its merits by the Clough Committee. Applications from PhD students are welcome but we expect that the costs of routine fieldwork will be met by your institution. Therefore you will need to make a clear and compelling case for additional support.

Applications should be submitted by email using this application form and should be supported by a letter from the applicant's institution or by a reference from a relevant person of suitable professional standing.. They should be submitted by 28th February for consideration in early March.

Recent Grants from the Clough and Mykura Funds

In 2009, Thomas Gernon of Trinity College Dublin (now at the University of Southampton) was awarded a grant in 2008 to study the volcanic geology of the Elie Ness diatreme, East Fife. Diatremes in this region have received little attention, but may provide insights into the architecture and internal workings of other types of volcanic vents. During August and September 2008, the volcanology of the diatreme was rigorously reevaluated, using a combination of detailed mapping techniques and sampling. Preliminary results from the mapping demonstrate that the diatreme had a protracted history of eruption and infill, involving contamination from a neighbouring vent. Petrography of the different
units is currently being undertaken, and a paper is in preparation. The author would like to thank the Geological Society of Edinburgh for supporting this research, which will help build a new and detailed picture of the processes and interactions of alkali basaltic diatreme-crater systems.

Brian O’Driscoll was awarded funds from the Mykura Fund to support ten days fieldwork on Unst (Shetland Isles) in July 2009. Together with colleagues from the University of Maryland (USA) and University College Dublin (Ireland), sampling was carried out across the lower portions of the ophiolite ‘klippe’ that is exposed there. This sampling focused on the section of the ophiolite that exposes the petrological Moho, where there are primary mantle heterogeneities preserved. In particular these include sequences of interlayered dunite and harzburgite that are believed to reflect varying degrees of partial melting at an ancient ocean-spreading centre. Abundant podiform Cr-spinel seams are also associated with this layering, and were also sampled. In September 2009, the samples were measured for Re-Os isotopes and highly-siderophile element (HSE) abundances at the University of Maryland. This data was combined with Cr-spinel mineral chemistry and in situ LA-ICP-MS measurements on sulphides and arsenides to investigate siting of the HSE. A complex history of ancient melt depletion, melt-rock interaction and sulphide metasomatism has been revealed. It is envisaged that this study will be relevant to deciphering mantle events preserved in other ancient ophiolites.

Adam McArthur of the University of Aberdeen was awarded a grant from the Clough fund in 2009 to support a field study of the Upper Jurassic Helmsdale Boulder Bed Formation in Sutherland, NE Scotland as part of his PhD project. The project is designed to integrate sedimentology with palynology to enable a better understanding of depositional systems and palaeoenvironments. Fieldwork was conducted over three weeks during April 2009 on the edge of the Inner Moray Firth Basin, which was an active rift basin during the Upper Jurassic. The entire Helmsdale Boulder Beds Formation, over 18 km of outcrop was logged in fine detail, totaling a sedimentary log 915 m thick. Each lithology was recorded, enabling the identification of thirty six lithofacies and seven key facies associations; siliciclastic siltstone, tiger stripe, sandstone (Fig 1.), siliciclastic boulder beds, calcareous siltstones, bioclastic turbidites and bioclastic boulder beds (Fig 2.). Fossil wood samples from the boulder beds were collected for a dendrology study of tree growth in the Upper Jurassic to assist environmental analysis. Palaeocurrent data was recorded at every opportunity, principally from echinoid spines within the sandstone and bioclastic turbidites. Furthermore 32 samples were collected at regular intervals and points of stratigraphical interest from the siltstone facies for palynological analysis. Palynological samples were processed at the University of Aberdeen and were used to identify a wide variety of over 130 palynomorphs.

Combined analysis of the lithofacies and palynofacies has provided some new insights into this classical section of Scottish geology. The key finding being a change in the depositional system, initially rich in siliciclastic material is seen to progressively change to a siliciclastic-starved system during the Lower Tithonian. High resolution biostratigraphy was used to constrain the ages of the sediments and this modification can be correlated with a large rise in sea-level in the Lower Tithonian wheatleyensis ammonite biozone. Integration of the palynofacies also helps to identify further causes for change in deposition, with palynofacies initially being dominated by lush lowland vegetation dominated by fern spores, to that of arid vegetation dominated by gymnosperm pollen.

Additional research is underway regarding controls on the depositional system. Correlation with the sea-level curve implies all facies barring the boulder beds facies are seen to corroborate with rising and falling sea-level in the Boreal realm, with pelagic siltstones being deposited during high sea-level and sandstones and bioclastic turbidites entering the basin during low sea-level. Whilst boulder beds are being utilized in a study of the frequency of large scale tectonic events during the rifting of the Inner Moray Firth.

In 2008 Ian Alsop of St Andrews University (now at University of Aberdeen) was awarded a grant from the Clough fund, which was used to explore structures in the Zechstein salt at a mine in Bex, Switzerland and compare these structures with folds and fabrics developed in metamorphic rocks.

The salt displays structures associated with deformation in the northern Alps and Jura mountains. A variety of detailed structures were observed within halite, gypsum, anhydrite and marl layers. The main features observed include: 1) Boudinage of more competent marl layers to form “boudin trains” (see photo). 2) Intense isoclinal folds. 3) Aligned pressure shadows around marl clasts to define a lineation. Collectively, these structures indicate that the salt was undergoing complex flow, with zones of both intense boudinage indicating layer extension, coupled with marked isoclinal folding reflecting contraction. Similar complexities are frequently observed within high strain zones developed in metamorphic rocks. Models of perturbations in flow developed in ductile shear zones may thus be equally applicable in salt tectonics.

In 2007 Colin Ballantyne at the University of St Andrews received funds to support fieldwork in Wester Ross, northwest Scotland. This involved collecting 20 samples for cosmogenic 10Be surface exposure dating, to calculate the timing of a glacial readvance in this area at the end of the last ice age. Provisional results from 9 samples suggest that the readvance occurred around 13,000 years ago, significantly later than had previously been supposed.

Madeleine Humphreys was awarded a grant in 2007 to fund to a group from the University of Cambridge and the University of Bristol, to undertake a study of columnar jointing in basalt on the island of Staffa. Despite recent advances, there is still considerable debate over the formation of these spectacular joint patterns. Fieldwork was carried out during August 2007. The group camped on Staffa for 6 days, and carried out sampling and measurements of the columns as well as mapping of individual lava flows. Results are now being analysed, and it is expected that the conclusions will be applicable to other areas.

In 2007 Ian Alsop received funds for fieldwork in Donegal. The objectives of this fieldwork were to gain a better understanding of (1) Extensional ductile structures related to possible orogenic collapse of the Dalradian and (2) The timing and kinematics of granite emplacement. This research has resulted in a paper entitled "The brittle evolution of a major strike-slip fault associated with granite emplacement: A case study of the Leannan Fault, NW Ireland" (Kirkland, Alsop & Prave 2008. Jour. Geol. Soc., vol. 165, pages 341-352) with another paper on ductile structures planned.
