BGS175: 175th Anniversary Science Symposium of the founding of the British Geological Survey, 28th September, Royal Institution, London
The British Geological Survey is the world's oldest national geological survey and commemorated its 175th anniversary in 2010.
The event was marked by a one-day science symposium on 28 September 2010.
The symposium showcased our world-class science and technologies, demonstrating their relevance, societal benefits and positive impacts in addressing 21st century challenges; including living with environmental change, energy and natural resource security, rising CO2 emissions and geohazards.
- Peak metal: Scarcity of supply or scare story?
- Bronze Age Mediterraneans may have visited Stonehenge
- Modelling of Icelandic volcanic ash particles
The event was attended by influential stakeholders including representatives from government, industry, academia, international geological surveys, students and the national media.
Guest speakers included Dr Marcia McNutt, and Professor Iain Stewart.
Britain's best-known natural history film-maker, Sir David Attenborough, featured in the panel discussion to close the symposium.

Edward Greenly (1861–1951)
Cofir am Edward Greenly yn bennaf am ei arolwg daearegol o Ynys Môn, gwaith y bu wrthi am bron pum mlynedd ar hugain o’i fywyd.
Image caption: Edward Greenly. Llun trwy garedigrwydd Terry Williams
Edward Greenly (1861–1951)
Campwaith pennaf Edward Greenly oedd cwblhau arolwg daearegol manwl o Ynys Môn. Cyhoeddwyd The Geology of Anglesey (Volume 1 and Volume 2) mewn dwy gyfrol yn 1919 ac yna yn 1920 fap daearegol ar y raddfa un fodfedd i’r filltir. Er bod rhannau o’r gwaith wedi’u diweddaru yn ystod y degawdau dilynol, erys ei astudiaeth yn glasur o fri rhyngwladol.
Mapio Môn
Wrth fapio ynys Môn, gwnaeth Greenly ddefnydd mawr o syniadau tectonig a ddatblygodd wrth iddo fynd i’r afael â gwaith maes cynharach yn Ucheldiroedd yr Alban. Roedd tair prif broblem yn ei wynebu: prinder brigiadau da, yn enwedig mewn ardaloedd mewndirol allweddol bwysig; presenoldeb creigiau gorchuddiol clytiog yn cuddio yn aml y baslawr Cyn-Gambriaidd hŷn; a phresenoldeb toriadau tectonig megis ffawtiau a chylchfaoedd croesrym a oedd yn aml yn rhwystro’r gwaith o gydberthyn gwahanol ddilyniannau o greigiau. Chwaraeodd ei wraig Annie Greenly (Barnard gynt), a oedd yn rhannu ei ddiddordeb mewn daeareg a diwinyddiaeth, rôl hollbwysig drwy baratoi’r mynegai i’w gyfrol.
Ganed Greenly ym Mryste ac fe’i haddysgwyd yng Ngholeg Clifton. Bu’n fyfyriwr yng Ngholeg y Brifysgol, Llundain, cyn ymuno â’r Arolwg Daearegol yn 1889. Yn gyntaf, bu gofyn iddo baratoi arolwg o Ucheldiroedd gogledd-orllewin yr Alban. Daeth yn ffrind agos ac yn gydweithiwr i Ben Peach yr oedd ei archwiliadau wedi bod yn gyfrwng i ddatrys adeiledd cymhleth yr Alban (gan gynnwys adnabod a sylweddoli arwyddocâd Gwthiad Moine). Rhoddodd Greenly y gorau i’w waith gyda’r Arolwg yn 1895 er mwyn iddo, o’i ben a’i bastwn ei hun. roi cychwyn ar ei arolwg o Ynys Môn.
Cyfraniadau pwysig i ddaeareg
Yn gydnabyddiaeth am ei gyfraniadau pwysig i ddaeareg, cafodd Edward Greenly ei dderbyn yn aelod er anrhydedd o gymdeithasau daearegol Caeredin a Lerpwl, a Chymdeithas Hynafiaethwyr Môn. Dyfarnwyd iddo Fedal Lyell, fawr ei bri, y Gymdeithas Ddaearegol yn 1920, medal Cymdeithas Ddaearegol Lerpwl yn 1933 a doethuriaeth er anrhydedd Prifysgol Cymru yn 1920.
Ar y cyd â Howel Williams, cyhoeddodd Greenly Methods of Geological Surveying yn 1930 a’i hunangofiant A Hand through Time: Memories Romantic and Geological a ymddangosodd yn 1938. Bu farw ym Mangor yn 1951 ac yn briodol iawn fe’i claddwyd ym mynwent Llangristiolus, Ynys Môn. Mae ei fedd wedi’i gyfnodi’n Safle Geoamrywiaeth o Bwysigrwydd Rhanbarthol (RIGS).

Marine deposits of chromite and olivine off Rum
Extract from the Rum Memoir
As Rum is a National Nature Reserve, exploitation of chromite or other ore reserves on land could prove environmentally unacceptable. The marine dispersal of resistate minerals derived by glacial and fluvial erosion of the rocks of the Rum Central Complex has been investigated as a possible alternative for mineral exploitation. Black, heavy mineral sand occurs on the rocky beach in the bay at Harris, although well-defined high-water-mark bands such as are known from the Northumberland coast (Gallagher, 1974) are absent. The inshore area along 28 km of the southern coastline of Rum were surveyed in 1987, between A' Bhrideahach in the west and Loch Scresort in the east (Figure 1) and surficial marine sediment collected at 91 sites in water depths of 50 m or less within 3 km of the shore. After dissolution of shell calcite averaging 20% by weight, analysis of small shipboard samples yielded mean values of 0.12% Cr2O3 and 3.5% Mg (Table 12).

Relatively high chromium and magnesium values were recognised from two areas representing submarine deltas off Harris and Dibidil; new analyses from these areas are presented in (Figure 64) and (Figure 65). In the bay off Harris, 3 km2 of sand sampled from the sea-bed surface in a mean water depth of 23 m contained on average 0.24% Cr and 7% Mg after removal of some 18% of shell calcite. The grade of the heavy mineral sands is therefore about 1% of chromite and 25% of forsteritic olivine from the mineral analyses given in (Table 13). It is concluded that tens of thousands of tonnes of chromite and more than 1 million tonnes of olivine and of calcite are present in the topmost 1 m of the Harris delta (utilising 2.2 g.cm-1 as the wet density). The peak anomaly of 4% chromite and 50% olivine lies 1.8 km offshore.
A smaller area of 1 km2 of heavy mineral sand is present up to 1 km off the mouth of the Dibidil River in a mean water depth of 19 m (Figure 64). After dissolution of approximately 30% contained calcite a small number of surface samples from the submarine delta (Gallagher, 1989) average 0.19% Cr, equivalent to about 0.8% chromite, and 4.5% Mg (15–20% of forsteritic olivine). The peak anomaly of 1.2% chromite occurs only 350 m offshore of the mouth of the Dibidil river. The figures indicate 10 000 tonnes of chromite in the top metre of the delta. Other isolated sample sites off south-west and south-east Rum are somewhat anomalous in chromium and magnesium, as might be expected from tidal dispersion, but further sampling will be needed to properly assess their significance.
A full evaluation of the true lateral extent and thickness of the deposits will require geophysical surveys and drilling of the deltaic sands. Heavy minerals will most likely be concentrated towards the base of the sand accumulations.
Mineralogy
The deltaic sediments are well-sorted medium- to fine-grained sands (125–500 pm) highly suitable for beneficiation by density or magnetic methods. The total amount of heavy minerals present increases with decreasing content of shell calcite, a feature which is likely to occur with depth in the deltas, and of quartz and feldspar. In five representative samples the total heavy mineral content ranged from 36 to 94% with olivine dominant, followed by clinopyroxene and orthopyroxene. Chromite-type spinels, magnetite and ilmenite make up 10–15% of the overall heavy-mineral fraction. Traces of platinum, palladium and gold were detected in a few of the samples (Gallagher, 1989).
From analyses of the main heavy minerals (Table 13), it can be seen that chromite averages 32% Cr2O3 (10.7–44.4%) and the olivine is forsterite-rich (FO87). Detailed investigation of 31 samples from and around the Harris and Dibidil deltas shows that the chromite and olivine, calculated on a calcite-free basis, form 0.22–3.98% and 5–41% respectively (Basham et al., 1989).
Benificiation trials yielded concentrates of 86% chromite and 78% olivine with recoveries of 60% and 50% respectively. The size range and composition of the olivine in the marine sands compared well with the desired range for refractory use (Griffith, 1984). The iron content of the chromite is higher on average than that of South African chromites (25% FeO); nevertheless, in ferro-chrome production the tendency is towards acceptance of increasingly higher iron content (Power, 1985).
