Important scientific research achievements of the year
Compile and complete a series of important maps. The geological maps of1:2.5 million moon,1:300,000 China and its adjacent areas,1:500,000 China metamorphic geological map, ophiolite structural map in western China,1:500,000 China geotectonics and oil-gas-bearing basins, China oil-gas area and major oil-gas-bearing basins were compiled. To undertake the compilation of a new generation of regional geological records of China, and complete 1 1 provincial (district) geological records; Participated in the development and construction of "One Geological China" and won the second prize of geographic information technology progress.
The research progress of Precambrian and metamorphism is outstanding. It is the first time to divide three ancient landmasses before 2.6Ga in the North China Craton. Determine the continental crust growth, major geological events and major magmatic events sequence of Jiaobei terrane; A two-way subduction and reentry model of the North China Craton is proposed. The research on the polymerization events in Proterozoic and the cracking events in Mesoproterozoic is of great scientific significance to the comparative study of the outward diffusion-cracking history in Proterozoic and Mesoproterozoic and the reconstruction of columbia supercontinent.
A series of achievements have been made in the study of important orogenic belts and structures. This paper puts forward a new definition and classification scheme, divides the large-scale deformation structures and deformation systems of Phanerozoic in Chinese mainland, and reconstructs the geodynamic environment of Phanerozoic in different geological periods in Chinese mainland. A new three-dimensional compression model of high Himalayan thermal collision orogenic belt is proposed for the first time. Discovery of the Paleo-Tethys arc root structure in Pamirs, Northeast China: Two possible patterns of India/Asia subduction collision "spatial difference subduction collision mode" and "time difference subduction collision mode" are put forward; The position of South China in Neoproterozoic Rodinia supercontinent is determined, and it is speculated that there is a "hidden" grenville orogenic belt in the southern margin of China. The Paleozoic tectonic evolution model of the northern margin of North China was established. It is determined that the Alashan block was located in the northern margin of the East Gondwana continent in the early Paleozoic, and the final assembling age with the North China block was the late Devonian.
New edition1∶ 30,000 geological map of China and its adjacent areas.
"One Geological China China", which participated in the development and construction, won the second prize of geographic information technology progress.
There are many discoveries in stratigraphic paleontology research. It is suggested that the age of the global Mesoproterozoic bottom boundary is17 million years. At present, the most complete carbon isotope variation curve and suspicious biostratigraphy of Ediacaran single section in the world have been established, and the division scheme of Ediacaran chronostratigraphy has been put forward preliminarily. A complete disc-shaped Guringia-like carbon film fossil was first discovered in Tongren, Guizhou. Through conodont research, the Permian-Triassic boundary section was found in Wenbudangsang, Geji County. Ruyang giant sauropod dinosaur fauna also fills the gap of China dinosaur fauna. The discovery of dinosaur egg in Xichuan County, Nanyang, Henan Province is of great significance to the study of dinosaur reproductive behavior and living habits. A new genus and species of Tyrannosaurus rex was discovered in Ganzhou, Jiangxi-China Ganzhou Dragon; A new bird-Gansu bird in Zhenxi was found in Jehol biota. The oldest fossil record of parental rearing behavior of prehistoric reptiles was discovered.
Skull and mandible of Qianzhoulong in China
Important progress has been made in geophysics and deep exploration. The deep process of lithospheric (crust-mantle) structural transformation between the marginal mountains of the Qinghai-Tibet Plateau and the peripheral craton is revealed, and the seismological evidence of lithospheric mantle behavior wedged into the northeastern margin of the Qinghai-Tibet Plateau from the North China craton is obtained. The Moho surface of the thick crust in the hinterland of Qinghai-Tibet Plateau is obtained, which gives new constraints to the crustal structure of Qiangtang terrane. The study of Longmenshan section shows that the large strike-slip fault on the eastern margin of Qinghai-Tibet Plateau limits the crustal thrust. It reveals the deep process of the closure of the Soren suture zone along the ancient Asian ocean, land-land collision and post-collision crustal proliferation. Seismological evidence that there is a thin lithosphere (60 ~ 70 km) in the southeast margin of South China continent is found.
New progress has been made in the application of isotope technology and the study of reference materials. The (U-Th)/He low-temperature thermal chronology technology has made important progress in the application research of petroliferous basins. The titanium isotope reference materials of basalt and various neodymium isotope reference materials have been developed and passed the national first-class reference materials evaluation. For the first time, the newly developed iron and magnesium isotope technique is used to directly trace the mineralized elements themselves and the major elements in the ore-bearing layer.
The research on sedimentary basins and resources and energy services has made a breakthrough in exploration. Three-dimensional seismic exploration of hydrate is carried out for the first time in China, and the drilling results are consistent with the prediction results. A systematic study of the trinity of geology, logging and geophysics has been carried out, which has laid a solid foundation for geophysical prediction of solid potassium deposits in Mengyejing area of Yunnan and liquid brine in Qaidam basin of Qinghai Province. The organic matter preservation model and the biological productivity model of Nen-1 member in Songliao Basin are established. A statistical analogy method is proposed to evaluate the potential resources of oil shale in large depression basins. Geological survey and mapping of late Mesozoic continental basins in northwest Hebei Province were carried out.
The research results of rock mineralogy have great influence in academic circles. "In-situ Diamond" was published, which was widely praised internationally and was written into the field manual; The discovery of deep minerals such as diamond, moissanite and coesite in six ophiolite belts around the world is considered to be a common phenomenon of ophiolite oceanic mantle peridotite, and it is necessary to re-examine the classical concepts such as oceanic mantle material composition and mantle movement. A new ultra-high pressure mineral was found in diamond. Experimental petrology shows that these ultrahigh-pressure minerals come from the depths of the lower mantle. These findings pose new problems and challenges to the traditional theory, and it is necessary to re-examine the shallow genetic theory of ophiolite and chromite.
