GIGCAS (Guangzhou Institute of Geochemistry under Chinese Academy of Sciences) is a state level non-profit scientific institution committed to basic and applied basic research and a key base for geochemical and environmental scientific research and related talent training. Its predecessor can be traced back to (Guiyang) Institute of Geochemistry under Chinese Academy of Sciences, which was newly founded based on a part of IGCAS (Institute of Geology under Chinese Academy of Sciences) according to the strategic requirements of the state in 1965. Being led by the older generation of scientists represented by Academician Tu Guangchi, and after hard work by the researchers and employees of several generations, GIGCAS has developed many branch disciplines of geochemistry, such as economical geochemistry, organic geochemistry, isotope geochemistry and mineralogy, etc., so making important historical contributions to the development of earth sciences and environmental sciences in China.　 

Ever since 2002 when GIGCAS was admitted to the CAS knowledge innovation program, GIGCAS has gained fast development, as its innovation capability was improved quickly. Currently, GIGCAS owns a state key laboratory, four provincial or ministerial key laboratories, and one joint laboratory of chemical geodynamics founded in cooperation with Hong Kong University. Also, GIGCAS has 17 laureates of CAS Program for 100 Outstanding Scientists, 14 laureates of National Science Foundation for Outstanding Young Scientists and 2 Excellent Innovation Teams crowned by National Natural Science Foundation. Important innovative achievements have been made in research fields like marine-continental lithospheric interaction, chemical geodynamics and mineral resources, ecological environment and sustainable development.　 

To construct an institute with potential of international competition in both earth sciences and environmental sciences is the common wish of all the staff in GIGCAS. For this purpose, we will enhance interdisciplinary integration and develop prospective and systematic research in regard to academic issues, which are related to state requirements and focused on lack of resources and energy as well as environmental pollution, aiming to attain innovative results of key importance and applicable achievements of key value. GIGCAS will further optimize its discipline layout, continue to innovate in its research system, enhance its capability in technological innovation, so as to lead the development of all its disciplines. Also, GIGCAS will continue to import excellent talents, push forward the process of construction of innovation teams, to further enhance cooperation with organizations and scientists in both China and foreign countries, so as to open a new situation for the development of GIGCAS.　 

In its marching process in the 21st century, GIGCAS feels much obligated for its tasks and aims. We would like to extend our sincere gratitude to the various circles and friends both at home and abroad, which are concerned seriously about the development of GIGCAS. We cordially invite excellent talents from both home and abroad to join us or cooperate with us, and we sincerely welcome excellent graduate students who are committed to research in earth sciences, resources and environment to be enrolled in our graduate programs. So let us work together, hand in hand, in regard to exploration and innovation, to continue to make new contributions to the scientific, social and economic development in China and the region!
