稀土资源的全球分布与开发潜力评估

 稀土是重要的战略资源,然而目前全球稀土储量难以满足未来需求,因此寻找和开发潜在的稀土资源迫在眉睫。建立了稀土资源开发潜力评估指标体系并赋予权重,评估了全球稀土资源的分布及开发潜力,得出如下结论：（1）稀土资源开发潜力评估指标体系由矿产资源开发潜力评估指标体系和政策环境评估指标体系构成,其中前者权重大于后者;（2）中国是轻稀土储量最多的国家,丹麦（格陵兰）的重稀土储量十分可观;（3）巴西的Prado矿、南非的Steenkampskraal矿、美国的Pea Ridge矿和俄罗斯的Tomtor矿是全球品位较高的稀土矿;（4）俄罗斯、丹麦（格陵兰）、澳大利亚、加拿大和美国拥有除中国外最具开发潜力的稀土矿床。面对海外稀土供应潜力的持续提升,中国须加强本国稀土资源的勘查力度,掌握国际稀土产业发展的最新态势,积极谋篇布局,充分利用国外资源并抢占产业的科技制高点,努力保证中国稀土资源的供应安全和产业链优势。

Quaternary folding in the south piedmont of central segment of Tianshan Mountains

The Tianshan Mountains are an important active structural belt in the interior of Eurasia. By integrated methods of surface geology survey and interpretation of seismic profiles, we distinguish fold scarps located at the south limb of the Kuqatawu anticline and the north limb of the Dongqiulitag anticline in the Kuqa rejuvenation foreland thrust belt, south piedmont of central segment of the Tianshan Mountains. Fold scarp is a newly found structural phenomenon. Because of the bend of thrust plane and the movement of hanging wall above the thrust plane, the original horizontal deposits of hanging wall and their surface become a monocline structure, resulting from the separating and migration of the active and fixed axial surfaces. Measuring the geometry of fold scarp and using the data of age of the deformed deposits, the crustal shortening rate resulting from the deeply seated subsurface thrust is calculated. The crustal shortening rate reflected by the fold scarp located at the north limb of the Dngqiulitag anticline is (1±0.1) mm/a. The fold scarps of the Dongqiulitag anticline and the Kuqatawu anticline identify that the deformation process of the crustal compressive structures in the Kuqa area extends into the Late Quaternary.     

Paragenesia of Quaternary pediments and river terraces on the north piedmont of Wutai Mountains

A study has been made of the paragenetic relations of the pediments and river terraces on the northern piedmont of Wutai Mountains via geomorphologic mapping of 1:10000 scale, and an analysis on the role of tectonic, climatic, and drainage factors in the parageneses. The Quaternary pediments and river terraces on the north piedmont of Wutai Mountains united to constitute six steps of geomorphic surfaces. The episodic uplifting of fault blocks was the dominant factor in the formation of the unified surfaces, however climatic change and drainage diversities led to undulation of the surfaces. The second terrace of Yangyan River (T2) was formed in the last glacial maximum, when the river was in aggradational state. The third to fifth terraces were formed in interglacial stages, when the river was in equilibrium or degradational state. It is inferred that climate had no insignificant effect on the river incision caused by tectonic uplifting. In light of terraces dating, since the Quaternary the Wutai fault-block mountains experienced six rapid uplifting events, and the starting time of the last four events was respectively 1.2, 0.6, 0.13, and 0.02 Ma B.P.

Assessment of wind energy potential in China

China wind atlas was made by numerical simulation and the wind energy potential in China was calculated. The model system for wind energy resource assessment was set up based on Canadian Wind Energy Simulating Toolkit （WEST） and the simulating method was as follows. First, the weather classes were obtained depend on meteorological data of 30 years. Then, driven by the initial meteorological field produced by each weather class, the meso-scale model ran for the distribution of wind energy resources according each weather class condition one by one. Finally, averaging all the modeling output weighted by the occurrence frequency of each weather class, the annual mean distribution of wind energy resources was worked out. Compared the simulated wind energy potential with other results from several activities and studies for wind energy resource assessment, it is found that the simulated wind energy potential in mainland of China is 3 times that from the second and the third investigations for wind energy resources by CMA, and is similar to the wind energy potential obtained by NREL in Solar and Wind Energy Resource Assessment （SWERA） project. The simulated offshore wind energy potential of China seems smaller than the true value. According to the simulated results of CMA and considering lots of limited factors to wind energy development, the final conclusion can be obtained that the wind energy availability in China is 700 - 1 200 GW, in which 600 - 1 000 GW is in mainland and 100 - 200 GW is on offshore, and wind power will become the important part of energy composition in future.     

Growth of the Huoersuosi anticline （north Tianshan Mountains） by limb rotation since the late Miocene

The Huoerguosi anticline, located in the north Tianshan Mountains piedmont fold-and-thrust belt, is a trending east-west fault-related fold. In the cross section along the Jingou River, its south limb is composed of the pre-growth strata of the Anjihaihe （E2.3a）, the Shawan （（E3-N1）s）, the Taxihe （N1t） and the lower part of the Dushanzi （N2d） Formations, trending east-west and dipping to south 55°, and the growth strata of the upper part of the Dushanzi （N2d） and Xiyu （（N2-Q1）x） Formations, dips of which decrease from 55° at the base of the growth strata to 47° at the bottom of the Xiyu （（N2-Q1）x） Formation to -0° at the top of the Xiyu （（N2-Q1）x） Formation. The strata at the north limb of the anticline are vertical or over-turned, and are cut by the breakthrough thrusts to result in the drag fold. In the depth, the anticline is symmetric, and its core comprises the Cretaceous and the Jurassic coal-bearing beds. In the seismic profile, the seismic reflectors of pre-growth strata at the south limb of the anticline dip to south constantly, and ones of the growth strata fan southward, whose dips decrease upward. The geometry of the south limb growth strata outcropped along the Jingou River valley and the deep structure of the anticline shown in the seismic profile indicate that the Huoerguosi anticline is a detachment fold anticline growing by limb rotation. Based on the growth model and magnetostratigraphic age, during the growing process of the Huoerguosi anticline, the average shortening rate absorbed by the south limb is -0.46 mm/a, and the average uplifting rate of the anticline is -0.86 mm/a which exceeds the average deposition rate, which is in accordance with the fact that the top of the anticline is intensely eroded. Considering symmetric geometry of the Huoerguosi anticline and ignoring the breakthrough thrusts, the shortening of the whole anticline should be more than -0.92 mm/a, doubling the shortening rate determined from the growth at the south limb.
