The State Key Laboratory of Organic Geochemistry (SKLOG) is affiliated with Guangzhou Institute of Geochemistry, Chinese Academy of Sciences (GIGCAS). GIGCAS, mainly engaged in modern geochemical and mineralogical research in terms of research orientations, puts a high preference on organic geochemical and isotope geochemical research and is actively exploring the new fields in environmental geochemistry, regional sustainable development and oceanic geochemistry, etc. With its abundant research and technical forces, GIGCAS mainly undertakes research and development in energy, resources and environment.
The State Key Laboratory of Organic Geochemistry (SKLOG) was approved for construction in 1989. In November 1992, SKLOG was evaluated and formally crowned as a state key laboratory. As a sponsor, SKLOG sponsored the founding of GD Key Laboratory of Utilization and Protection of Environmental Resources, the first of its kind in Guangdong Province and actually a product of cooperation between Chinese Academy of Sciences and Guangdong Provincial Government.
At present, Prof. PENG Ping’an acts as the director of SKLOG, while Prof. FU Jiamo, a CAS academician, serves as the director of its academic committee. SKLOG now has 41 permanent staff, among which there are 29 staff scientists, 10 technicians (including 6 project-sponsored staff) and 2 managers. Here 1 holds CAS academician title, 24 hold senior academic titles, 7 are Ph.D. advisors. A workstation for floating post-doc researchers was set up in this laboratory. Currently there are 9 post-doc researchers, 89 Ph.D. candidates and 57 M.Sc. students working in this laboratory.
The strategic requirement by the state for petroleum and gas resources and environment in the last decade as well as the development trends of the discipline of modern organic geochemistry has always been the driving forces for determining the research orientations of SKLOG. SKLOG’s major research orientations cover the following: 1) petroleum and gas geochemistry, 2) environmental organic geochemistry, and 3) biological geochemistry. For petroleum and gas geochemistry, our attention is focused on scientific issues such as the geochemical processes and dynamic mechanisms of the formation of basins, petroleum and gas reserves, and origin of unconventional petroleum and gas resources, etc. For environmental organic geochemistry, our attention is focused on the environmental behaviors, pollution mechanisms of toxic organic pollutants (TOPs), in view of the environmental issues as brought forward by the rapid development of the economy in the Pearl River delta region. As for biological geochemistry, our attention is directed to the geochemical processes related to carbon cycle and water cycle, mainly by means of hydrocarbon and hydrogen isotopes and biomarkers, and to provide evidence for global climatic changes in terms of mechanism.
In the past several years, a number of high-level research achievements have been made by SKLOG in petroleum and gas and molecular organic geochemistry and environmental geochemistry, two projects were awarded gold prizes in scientific and technological progresses at national level, two other projects were awarded silver prizes for scientific an technological progresses at national level, one project was awarded bronze prize in natural science at national level, and more than 20 projects were awarded prizes in natural science or for scientific and technological progresses at ministerial or provincial level. In 2000-2002, more than 370 papers in total were published in national and international journals that are academically significant, among which 83 papers were published in international SCI journals, 38 papers in domestic SCI journals and more than 200 in domestic core journals. These papers have produced a great impact in the national and international scientific communities. Moreover, SKLOG were awarded 2 state invention patents and 11 practicable new patents.
Molecular organic geochemistry has been being the preferential discipline for development in SKLOG, and in this respect, SKLOG is internationally renowned for its molecular organic geochemical research. In the past several years, several dozens of new biomarker compounds in geological bodies have been discovered and their geochemical significance has been studied by SKLOG, which has provided new indices for the assessment of the origin of oil-sourced rocks, depositional environment and maturity of organic matters, etc. SKLOG has also carried out a great number of research projects about Tarim Basin, Sichuan Basin, Erdos Basin, Junggar Basin, Dongpu Basin, the Mesozoic and Cenozoic basins in North China and other oil-bearing basins, attained a series of research achievements, and made significant contributions toward the development of the petroleum and gas generation theories in China. Our representative research achievements include the geochemistry of coal-generated hydrocarbons, and the study about the molecular biomarkers in geologic bodies. The project of the geochemistry of coal-generated hydrocarbons was awarded the silver prize in natural science by CAS (Chinese Academy of Sciences) in 1992. This project systematically summarized the theories about coal-generated hydrocarbons as proposed by scholars in China, proposed a comprehensive method for differentiation and identification of coal-generated oil and gas, and established the model for the formation of coal-generated hydrocarbons, which has pushed forward the evaluation and exploration of coal-generated hydrocarbons in China. As to the project of the study about the molecular biomarkers in geologic bodies, it was awarded the bronze prize in natural science by the state, and its innovative content covers: the discovery of new biomarkers such as lanostanes, sulphur-bearing lanostanes, botryococcanes, unknown porphyrins and so on in geological bodies, the development of the study of the geochemical application of a series of new biomarkers (which includes the division of the depositional environments for lacustrine oil and sediments by comprehensively applying multiple biomarker indices for the first time in China), the advancement of the non-kerogen formation theory of high-sulphur immature oil and its evidence, and the identification of molecular biomarkers that can be used to trace the various kinds of pollution sources as a result of the extension of the concept and the related theory of biomarkers in the field of environmental geochemistry. All these research achievements have helped to enhance the terrigenous oil formation theory as was proposed in China, have resulted in the realization of as much as 20 million yuan in terms of economic benefit for the Liaohe oilfield when these achievements were applied in oil exploration, and have led to the increase of 10 million tons of reserves for immature oil. Moreover, a number of new research fields such as reserve formation dynamics, reserve formation chronology, petroleum and gas field exploration geochemistry and biological organic geochemistry, etc., have also been developed at SKLOG, and some preliminary research achievements have been made in this State Key Laboratory of Geochemistry.
In the field of environmental geochemistry, our attention has been focused on the toxic organic pollutants (TOPs) in the environment, a frontier field and hot topic for the international environmental research. SKLOG has set up and perfected a systematic separation and analytical procedure and a quality assurance and quality control (QA/QC) system toward micro-TOPs, and our analytical methods and our data quality are comparable to those by the international scientific community. Furthermore, the staff scientists in SKLOG initiated research on the distribution, migration and transformation of POPs and VOCs in the atmosphere, water and sediments in the Pearl River delta region, explored the biogeochemical processes and sources of POPs by utilizing molecular markers and compound-specific isotopes, etc., and carried out study on the mechanisms of biodegradation and non-biodegradation of POPs and their possible applications. In general, SKLOG has attained remarkable achievements in these related research fields.
Meanwhile, SKLOG has initiated very extensively a series of domestic and international academic exchanges and cooperation activities for a long time. We have ever successfully hosted and co-hosted a great number of national and international academic conferences, which has helped greatly to push forward the launch of academic activities and academic exchange. In the past years, we have established cooperative relationships with world-renowned organic geochemistry labs in U.K., U.S.A., France, Australia, Canada and so on. Up to now, SKLOG has sent out more than 100 person-time of our staff abroad to deliver lectures, to take a visit, to get trained, to learn, to conduct collaborative research and to be co-cultivated graduate students. Also, the Lab has invited and received around 100 person-time of foreign scholars and experts to deliver lectures, conduct exchange, and carry out cooperative research, etc. here at SKLOG. All these domestic and international academic exchanges and cooperation have in turn promoted the flourishing of our research achievements, the cultivation of young talents and the incessant upgrading of our academic and technological levels.
After years of hard efforts, SKLOG has been constructed into a laboratory equipped with advanced equipment and abundant technical forces, and a lab that is in the lead in the national scientific community and can produce an important impact in the international circle. SKLOG owns a large cohort of research scientists who are of high quality and well experienced, and has a large number of post-doc researchers, Ph.D. candidates and M.Sc. students who are vigorous and energetic in formulating their scientific ideas. Also, talent cultivation work is well done in this laboratory, as 17 staff scientists were specially promoted by the Chinese Academy of Sciences as professors, associate professors or senior engineers, and the youth talents as cultivated in this laboratory have already undertaken key tasks in both research and management. As required by the CAS Innovation Program, a set of operation management mechanisms were established and gradually perfected in SKLOG. A system of appointment and periodic examination was adopted for SKLOG’s permanent staff, and any vacancy will be filled through public advertisement and open competition. Centralized management was carried out toward SKLOG’s large-scale instruments and equipment, which are to be opened for operation by visiting scientists. And the number of the technical personnel can be reduced as long as the efficiency can be improved. Moreover, a set of operation regulations, detailed management systems as well as meticulous safety rules for the various analytical methods and instruments and equipment were stipulated, and standardized management was implemented. In this way, SKLOG’s scientific and technological research is pushed on to a new platform.
In recent years, SKLOG has made remarkable progresses in contracting for state research projects, in elevating our research skills, and in constructing the lab, and has since attained plentiful research achievements. With the increase of the state investment for foundation research and the reform, innovation and perfection of our own regulations, we believe that SKLOG will continue to play an ever increasing and irreplaceable role in the research concerning energy construction and environmental protection in China.
