Key Laboratory for Metallogenic Dynamics TEXT SIZE: A A A

Ore mineral resources are the prime necessity for the survival and development of modern society. Substantial supply of mineral resources is a prerequisite for healthy and sustainable development of national economy. Guangzhou Institute of Geochemistry has long been emphasizing on comprehensive study of ore mineral resources, and excels in areas such as granite and related ore mineralization, strata-bound deposits, superlarge ore deposits, ore-forming fluid, experimental metallogeny, and thus been bestowed many provincial and national awards for distinguished contributions. Key Laboratory for Metallogenic Dynamics was established in May 2005 on purpose of conciliating theoretical research and state demands, and enhancing the potential of independent and original innovation of our institute. 

The laboratory is emphasizing on comparative metallogenic investigations of massive mineralization domains and superlarge deposits in South China, Central Asia, and Qinling Orogen, and striving to settle key scientific questions concerning metallogeny and ore exploration. As an important research base for ore mineral resources in South China, we are endeavoring to cultivate an active researching team and become a state key laboratory with worldwide influence. 

Our laboratory consists of a faculty of 16 research staffs and 2 technicians, with Dr. Chen Yanjing as the director, Dr. Xiong Xiaolin and Dr. Zhao Taiping as deputy directors. Besides, 25 graduate students and 5 post-doctorates now study here. We have established cooperation relationship with many famous universities and research institutions abroad. 

Main research areas of our lab include: 1) origin and distribution of superlarge deposits and massive mineralization domains; 2) ore-forming processes in continent-continent collision system; 3) hydrothermal fluid system and hydrothermal mineralization; 4) magmatism and related ore mineralization; 5) basins and oil and/or gas traps; 6) expecting and reconnaissance of ore deposit. The areas are briefly introduced as follows. 

Origin and distribution of superlarge deposits and massive mineralization domains. Studies in this area was first advocated and leaded by Prof. Tu Guangchi in late 1980s, and two cycles of National Basic Research Program of China on this subject, all of which were chaired by scientists from our lab, Prof. Tu Guangchi and Prof. Zhao Zhenhua, respectively, have been carried out. Researches in the near future will focus on system and detail investigation of massive mineralization domains with clusters of superlarge deposits (i.e., South China, Qinling, Eastern Tibet, etc.), especially the global tectonic background for the explosive formation of superlarge deposits, to approach a substantial understanding of the origin of and factors controlling the distribution of superlarge deposits. 

Ore-forming processes in continent-continent collision system. Collisional Fluidization and Metallogenesis model (CFM model) was first proposed by Dr. Chen Yanjing in 1990, the model emphasizes the metamorphic dehydration and melting of the subducted slabs which resulted in the formation of magma and ore-forming fluids, while the transition of extrusion to extension was crucial for magmatism, fluid movement and mineralization. Experimental geochemical studies on the formation of mineral resources (include oil and gas) as well as comparative studies of worldwide orogenic belts will be our priorities in this field of study. 

Hydrothermal fluid system and hydrothermal mineralization. Investigation of inclusions entrapped in minerals and modern hydrothermal system is the most direct way to explore ore-forming systems. Prof. Lu Huanzhang is an internationally geochemists specialized in inclusion researches. Pof. Li Chaoyang is a well-known expert on various types ore mineralization. The two professors are now leading a few of our young scientists in endeavor to establish a world class laboratory for fluid inclusions and ore-forming fluid system study. 

Magmatism and related ore mineralization. Many ancestor scientists of our institute have contributed distinguished achievement on the study of magmatic activity and related mineralization. Nowadays, Prof. Zhao ZhenHua and Prof. Xiong Xiaolin are two most active and famous scientists on adakitic magmatism and mineralization study. Prof. Qiu Yuzhuo and Prof. Liang Huaying concentrate on studies concerning high-K calc-alkaline magmatism and related mineralization; Prof. Zhao Taiping and his group focus on studies of mantle plume, lithospheric events and related mineralization; Dr. Bao Zhiwei is interested in researches of continental collision and post-collision magmatic ore-forming processes. 

Basin-Range system and oil-gas entraps. Terrestrial facies oil-generating basin is a unique phenomenon in China, and study of basin and orogenic belt is an important to investigate the crustal lithosphere dynamics and evolution. Dr. Chen Genwen and coworkers study intensively on the generation, migration, and deposition or entrapment of both organic and inorganic fluids from the point view of juxtapose and decoupling of basin-range system. 

Experimental geochemical study of ore-forming processes. Experimental studies in the near future will focus on 1) metamorphic reaction of sediments and crustal material under high temperature and high pressure, 2) dynamics of ore forming fluid, 3) partial melting of mantle or crustal materials and the formation of adakitic magma, alkaline magma and granitic magma under high temperature and high pressure. These experiments will surely contribute to the development of metallogenic theory. 

Expecting and reconnaissance of ore deposit. Aiming at a breakthrough in large-, super-large ore deposit reconnaissance, we will combine metallogenic researches on South China, Central Asia and Qinling orogen with new technologies such as high-resolution, large-depth and light geophysical exploration techniques, GIS, shallow floating-point earthquake, continuous electrical conductivity (EH-4), to locate the hidden ore bodies. Prof. Chen Guanghao and Wang He have fulfilled many fruitful works in this line. 

The research orientations mentioned above will supply ways to approach following scientific questions: (1)The formation of giant deposits or massive ore mineralization areas in south China; (2) Mesozoic tectonic transition and explosive mineralization in south China; (3) The unity and distinction of the circum Yangzi mineralization; (4) The geodynamics background and mechanism of explosive mineralization of various ore deposits in Qinling orogen; (5) The predominant type of mineral deposits and their perspective in central Asia orogenic belt.

Key Laboratory for Metallogenic Dynamics of Guangzhou institute of Geochemistry is forging an advanced working platform with an active and creative research team of ore geology studies. We warmly welcome ambitious young scientists of domestic and abroad to join our team!
