The Geological Society of Sri Lanka The Geological Society of Sri Lanka (GSSL) was established in September 1983 during the first International Symposium on the Geology of Sri Lanka held at the University of Peradeniya as a non-profit scientific society. It has been the only one of the preeminent geological organization in Sri Lanka. The main objective of the society is to promote dissemination of all aspects of geological knowledge within Sri Lanka and to look into the interests of the individuals and organizations involved in the field of geosciences. The GSSL is working with any interested group in planning symposia and other type of meetings related to geosciences. It will also advocate the improvement of employment standards of professional geologists in various organizations and will also assist

undergraduates to improve their geological knowledge. The Journal of the society is the flagship publication which publishes peerreviewed articles under the category of review articles, research papers, short communications and book reviews. It is now published as open access journal. In addition to the Journal published annually, Society also publishes quarterly newsletters and ventures on producing occasional special publications too. Information is also disseminated through its website; www.gsslweb.org. The annual sessions of the Society are held at the last Friday of February each year, and it’s the forum for presentation and discussion on current geoscience research.

2. SHORT BIOGRAPHICAL STATEMENT & CAREER RECORD Kapila Dahanayake, in mid-1949, at the age of four years had his first stint in schooling at G/Ihalagoda Government School, Akmeemana where his mother was a teacher of the tutorial staff. Later in 1950, he was admitted to the Montessori class of All Saints’ College, Galle. In 1951, he joined the Std. 1 class at St. Aloysius’ College, Galle from where he sat the G.C.E (O.L) in science subjects in 1960. For subsequent studies leading to his G.C.E (A.L), he attended Mahinda College, Galle. Based on G.C.E (Advanced Level, 1964- Science) results, st he was selected to follow a 1 year General Science Qualifying (G.S.Q.) physical science course in mathematics, chemistry and geology at the Faculty of Science of the then University of Ceylon, Peradeniya. Based on G.S.Q. results, he was selected to follow a 3-year B.Sc. General degree course in geology, pure mathematics and chemistry. During the middle of the third year, he was selected to follow the B.Sc. Special Degree Examination in Geology held for the first time in Sri Lanka in 1969 and thus was in the first batch of students to pass nd the BSc Geology Special Degree examination in Sri Lanka with 2 class honours. Since then he served in the University of Peradeniya starting as assistant lecturer in 1969 till 2010 when he retired as Senior Professor of Geology. In 1971, he proceeded to France on a postgraduate scholarship from the French Government. He studied at France’s prestigious - Ecole Nationale Superieure de Geologie appliqué et de prospection miniere (ENSG) in Nancy. After having passed the postgraduate Diploma in Geology (DEA) at the University of Nancy, he did research studies at ENSG on the sedimentology of Jurassic limestones. Extensive field studies were done in the Paris Basin

i

and Jura mountains (France and Switzerland) and in Gandia and Barcelona (Spain). He also followed a 2-month vacation course on petroleum aspects of limestones at Elf Aquitaine Petroleum Company in Pau, France. In 1974, he was awarded the doctorate with felicitations of the Jury with TRES BIEN (Very Good) mention for his thesis written entirely in French and published later by the ENSG. The thesis work resulted in five publications (in French/English) in prestigious international journals. In 1975, he returned to Sri Lanka and taught mainly palaeontology, stratigraphy and sedimentology to undergraduates. He had to teach igneous and metamorphic petrology also due to staff shortages. His research interests flourished in Sri Lanka with grants from NSF (National Science Foundation) and its predecessor –NARESA and International Development Research Centre (IDRC), Canada. He was the first to conduct research work on the sedimentology and source rocks of gemstones mined on a large scale in Ratnapura, Pelmadulla and Balangoda areas. The research findings were published in Mineralium Deposita and received wide acceptance and international acclaim. Some of his findings are currently known even to gem miners who now start gemming soon after the occurrence of a landslide on gneissic rocks. With support from BRGM, he was able to identify locations of occurrence of bauxitic lateritse in Horana and Diyatalawa regions. Since 1985, Professor Dahanayake has conducted extensive research on biomineralization and occurrence of ooids and oncoids in carbonate and phosphate rocks. Such work done with Professors Krumbein and Reineck at Oldenburg and Wilhelmshaven Universities in Germany during Professor Dahanayake’s research stay in Germany as an Alexander von Humboldt Fellow helped to throw light on the origin and structure of coated grains present in carbonate and phosphate rocks in papers published in international journals. Such work on coated grains has shed light towards better understanding the origin of kidney stones as well as manganese nodules. A dedicated researcher, Professor Dahanayake has received many research grants and support from national granting agencies such as NARESA and NSF and international agencies such as International Development Research Centre (IDRC), Canada, Bureau de Recherchés Geologiques et de Minieres (BRGM), France and International Fertilizer Development Centre (IFDC), Alabama, U.S.A. He had been keen to assist in the research work of university students. In that endeavour, he has been able to produce number of geology postgraduates and undergraduates at the University of Peradeniya. He has thus supervised 10 M.Phil./M.Sc. postgraduate theses and a multitude of B.Sc. theses in a teaching and research career spanning to more than four decades. In 2003, Prof. Dahanayake received Sri Lankan Presidential award for scientific research. Prof. Dahanayake has more than 100 publications in national and international journals such as Nature, Naturwissenschaften, Sedimentary Geology, Mineralium Deposita, Natural Hazards, British Journal of Engineeing Geology and Hydrogeology, Bulletin of the French Geological Society (B.S.G.F), Review of Paleobotany and Palynology, Chemical Geology, Marine Geology, Science of Tsunami Hazards and Journal of International Society for the prevention and mitigation of natural hazards etc. Since his undergraduate days at Peradeniya, Professor Dahanayake has been keen to popularize geosciences among his peers, general public, school children and state employees. His intention being mainly to disseminate knowledge particularly about natural disasters such as floods, landslides, subsidence, earthquakes and tsunamis. In this endeavour, he has been supported by state and private print and visual media. Also, he regularly conducts many awareness programs among the general public, school children and state employees about landslides, earthquakes and tsunamis all over the country and particularly in the Central province. Also, he is often invited by Disaster Management Centre (DMC), Central Provincial Council, Ministry of Social Services and other organizations to address seminars and workshops conducted by them to create awareness about disasters. ii

The efforts of Professor Dahanayake towards popularization of geosciences to understand natural disasters were duly acknowledged by the Sri Lankan government particularly in 2005, when he was invited to address the Sri Lankan Cabinet of Ministers chaired by the President, His Excellency Mahinda Rajapaksa on the subject of landslides. Also after the 2004 tsunami disaster, in 2005, he was invited by the government to attend the post-tsunami conference of scientists to understand the tsunami mechanism organized at the office of the Japanese Prime Minister in Tokyo. As part of this visit, the Japanese government had arranged visits to Japanese Meteorological Agency (JMA) in Tokyo and other Disaster Management projects such as tsunami walls, Refugee Centres in tsunami-prone coastal areas etc. Earlier in 2005, he was also invited to address the Sri Lankan Parliament by the Parliamentary select Committee on Disaster Management on the themes landslides, earthquakes and tsunamis. Later on, he was invited to join as the scientist of the delegation of parliamentarians of the select committee led by Hon. Mahinda Samarasinghe MP that visited Australian DM institutions in Melbourne, Sydney, and Perth and other cities which included the Australian Geological Survey. Professor Dahanayake was the recipient/team leader of a substantial grants from NSF to study sedimentological, hydrogeological and engineering aspects of 2004 Indian Ocean tsunami. The work resulted in several international publications in indexed journals. Professor Dahanayake is known as a successful administrator in Sri Lanka, particularly in the domain of sciences. He started his administrative career as a Sub-Warden of a university student hostel (Akbar Nell Hall) on passing out from the University of Peradeniya as a B.Sc. honours graduate in 1969. From 1976-83, he served as Warden James Peiris Hall, University of Peradeniya. In 1983-84, he served as Head of the Geology Department at Peradeniya. During the period 1985-1996, he has served as Acting Director, Deputy Director, Senior Fellow and Coordinator of the Institute of Fundamental Studies (IFS), Kandy, Sri Lanka from 1989-93. He was the first Director of the Science Education Unit of the University of Peradeniya from 1997-2003. He served as the first Director of Postgraduate Institute of Science, University of Peradeniya. During part of this period (1998-2001), he also worked as Chairman, NSF. In recognition of his administrative capabilities, he was elected unanimously as the Chairman of Golden Jubilee (1942-1992) celebrations committee of the University of Peradeniya by its Senate in 1991. During a 12 -month period in 1991-92, Professor Dahanayake was able to successfully conduct more than 25 events such as- to quote a few- Jubilee Engineering Exhibition, Jubilee Science exhibition, Jubilee Medical exhibition, Jubilee Drama Festival, Jubilee Sports Festival, a series of TV programs via national channel – Rupavahini, and at the conclusion of one year of celebrations, the Issue of the Jubilee stamp by the state Postal Department.
