Overview of work and completed workload

In view of the scientific research nature and requirements of this project, as well as the natural geography and difficult logistics support of the research area, the Geological Survey Institute of Xinjiang Uygur Autonomous Region organized a project research team of young and middle-aged technical backbones with working experience in alpine regions and a new round of regional adjustment with a price of 1.25 million, and hired a number of experienced experts and retired senior engineers to further enrich the technical force, which is also the basis for completing the task on time with good quality.

Since June 65438+ 10, 2000, a project team has been established, and research on1:250,000 mapping method guide has been organized. On the basis of fully collecting and digesting predecessors' data, field investigation, reconnaissance and trunk profile measurement, the overall design of/kloc-0: 250,000 regional survey in Tage area of Mu Zi was submitted in June 2000. After preliminary examination by Xinjiang Geological Survey Institute, in September, 2000, the overall design of the regional survey of Tage area 1: 25 in Mu Zi was issued. It meets the overall design requirements of1:250,000 area mapping method research project, and agrees to report it to Northwest Project Office of China Geological Survey for approval. Then, the review was organized by China Geological Survey in Chengdu on June 5438+ 10, 2000, and it was considered that the guiding ideology of the design was clear, the thinking was clear, the research content was related to the characteristics of orogenic belts, and the research method was feasible. The problems that need to be clarified in theme design are emphasized, and it is pointed out that each theme design should be further supplemented and improved according to the theme design. In particular, it is necessary to further strengthen field observation, increase field information, do a good job of combining field and indoor, and give an evaluation of 9 1.6 (excellent level).

According to the design approval, the project team immediately carried out field research. Under the direct leadership of Northwest Project Office of China Geological Survey and Geological Survey Institute of Xinjiang Uygur Autonomous Region, the project team gave full play to the enthusiasm and creativity of every scientific researcher, carried forward the spirit of hard struggle, fought the plateau, resisted the cold, climbed mountains and climbed mountains, and endured hardships and sweat. After two and a half years of field research from April 2000 to June 2002, in June 2002, the field data of Mu Zi Tower Grid Scale1:250,000 were checked and accepted by China Geological Survey. According to the acceptance resolution, during the two-year field work, the comrades of the detachment overcame the adverse effects caused by various factors such as the harsh natural environment, successfully completed all the surveying and mapping and special research tasks specified in the task book and the overall design book, arranged the work reasonably, obtained solid first-hand information and achieved some preliminary results, and the workload could meet the research requirements. Agree to end the field work and switch to indoor comprehensive layout, and give excellent field work evaluation (88.6 points). See table 1- 1 for the physical workload of this project.

The input, typesetting and printing of the report are completed by Xinjiang Remote Sensing Center. The specimen, chemical analysis and particle size analysis of the sample are analyzed by the laboratory of the first regional geological survey brigade of the Bureau of Geology and Mineral Exploration and Development of Xinjiang Uygur Autonomous Region; Macropaleontology was identified by the Paleontology Research Office of the First Regional Geological Survey Brigade of the Bureau of Geology and Mineral Exploration and Development of Xinjiang Uygur Autonomous Region; Micro-paleontology was identified by the Institute of Xinjiang Petroleum Administration; Feng Qinglai of China Geo University identified radiolarians and conodonts. Silicate, quantitative spectrum and rare earth elements were tested by the laboratory of Geology and Mineral Exploration and Development Bureau of Xinjiang Uygur Autonomous Region. Rare earths and isotopes are detected by Chinese Academy of Geological Sciences and Yichang Institute of Geological Sciences. The electron probe was identified by Xi 'an Institute of Geology and Mineral Resources. Microphotography was completed by An Qigui, a senior engineer of Geological Survey Institute of Xinjiang Uygur Autonomous Region.
