Enantiornithine Birds in China

A brief introduction to the morphology, flight, size, habits, diet, feathers and systematic paleontology of fossil enantiornithine birds known from the Mesozoic of China is provided. Enantiornithine birds were the dominant land birds of the Mesozoic (245–65 Myr). Although they show great morphological differences from modern birds, their diversification in many respects mimics that of the modern land bird radiation and the reasons for their extinction at the end-Cretaceous remain a mystery.

中国天然气水合物

天然气水合物是一种规模巨大的新型潜在能源,因其具有分布广、规模大、埋藏浅、能效高、污染低等优点,是后石油时代的最佳接替能源之一。世界各国特别是各能源短缺国家非常重视天然气水合物的调查研究工作,其研发重点已从资源勘查逐渐向开发利用方面转移。中国正在进行第三个阶段天然气水合物工作,已在海陆发现3处天然气水合物产地,并在祁连山成功实施天然气水合物试开采,计划在2017年实施海底天然气水合物试开采。随着勘查试开采技术的不断进步和国家一系列扶持性政策的实施,中国将与世界先进国家同步实现天然气水合物的商业性开发,并最终实现产业化。

Time-dependent seismicity in China

Precise zonation of the territory of China has been performed based on the active known faults, type of faulting and seismicity level. One hundred and forty seven seismogenic regions were defined, forming 10 larger seismic areas, and the seismotectonic characteristics in each one of them were investigated in detail. After checking for data accuracy and completeness of the shallow earthquakes (h≤60 km), the regional time and magnitude predictable model was applied and the model parameters were estimated. Based on the model applicability in the studied area, probabilities for the occurrence of strong (M≥6.0) earthquakes during the next 10 years were calculated for each seismogenic region. Statistical tests have been used proving the superiority of the model in comparison with the time independent one, as well as in comparison with the actual earthquake occurrence.     

Land subsidence in China

Land subsidence in China occurs in different regions. It is primarily caused by excessive groundwater withdrawal. Other reasons for the subsidence include the oil, warm groundwater withdrawal and the neotectonic movement. The common characteristics of land subsidence in China are slow, accumulative, irreversible, and other unique properties. The range of subsidence still keeps extending and the accumulative subsidence increasing though some measures taken. Adjustment of the aquifer exploitation practice is a subsidiary way to control land subsidence, but it cannot solve this problem completely. In a specfic way of groundwater changing, the contribution of a certain soil layer to the total subsidence depends on its compressibility and thickness. Besides the elasticity, both cohesive soil layers (aquitards) and sand layers (aquifers) are observed to be plastic and creep when the groundwater level fluctuates in a specific way, which often leads to subsidence delay.

Uranium Provinces in China

Three uranium provinces are recognized in China, the Southeast China uranium province, the Northeast China-Inner Mongolia uranium province and the Northwest China (Xinjiang) uranium province. The latter two promise good potential for uranium resources and are major exploration target areas in recent years. There are two major types of uranium deposits: the Phanerozoic hydrothermal type (vein type) and the Meso-Cenozoic sandstone type in different proportions in the three uranium provinces. The most important reason or prerequisite for the formation of these uranium provinces is that Precambrian uranium-enriched old basement or its broken parts (median massifs) exists or once existed in these regions, and underwent strong tectonomagmatic activation during Phanerozoic time. Uranium was mobilized from the old basement and migrated upwards to the upper structural level together with the acidic magma originating from anatexis and the primary fluids, which were then mixed with meteoric water and resulted in t
