中国东部6区域近1000年干湿序列的重建和气候跃变分析

本文利用我国的历史气候记载，为东部6区域重建了最近1033年的时间分辨率为1年的区域于湿气候序列，讨论其可靠性，并分析其变化的准周期性和跃变特征。跃变分析采用移动t检验方法，分析各区域干湿气候的世纪尺度和10～20年尺度的跃变现象，辨识跃变信号的参考年代，指出北方各区域的跃变趋势相同，但有时与长江下游地区相反，以及跃变信号在寒冷气候背景下较多出现等特点。     

第四纪地质定年与地质年表

时、空、质(物质)、能(动力)是研究地质过程、环境演变的基本要素，其中时间是关键．任何一个自然事件、任何一个地质过程，都与时间相关联，时间的重要性需要通过年龄的精确测量来体现。本文综述了第四纪定年的基本方法和特点以及近年来年代地层学所获得的进展，提出了中国第四纪的划分简表。     

甘肃桦树沟(铁)铜矿床的成因机制

矿床地质地球化学特征研究结果表明，随着古陆边缘弧－槽－盆体系的发生与发展，元古代基底火山（沉积）岩系经深循环水（海水）－热系统的作用，成矿物质被浸出和搬运，并经海底喷溢作用沉淀于海盆洼地中形成桦树沟矿床含铜建造，后期变质作用使成矿物质活化、转移和富集。桦树沟矿床为喷气（流）沉积－变质改造型（铁）铜矿床。

Integral Evolution Pattern of Intraplate Seismicity in Chinese Mainland and Its Periphery

Taking the active fault network as the structural frame, the Chinese mainland and its periphery can be regarded as a system of "fault movement and seismogeny." By using the self-coupling method, preliminary study shows that the seismogenic system is a time-ordered dissipation system. The time order in the state far from equilibrium is established and maintained through mass and energy exchanges between the system and the surroundings. The evolution of the seismogenic system follows some properties of unbalanced phase change, namely, critical retard, bifurcation, entropy reduction, etc.     

Magnetostratigraphy and palaeoclimate of Red Clay sequences from Chinese Loess Plateau

Two Red Clay profiles near Xi’an and Xifeng were investigated in an attempt to determine magnetostratigraphic and palaeoclimatic records. The results show that aeolian dust accumulation and the related East Asia palaeomonsoon system had begun by 6.5 Ma, and it is deduced that the Tibetan Plateau had reached a significant elevation at that time. The late Tertiary palaeoclimatic history of the Red Clay as reflected by magnetic susceptibility is reconstructed during the period of 6.5–2.5 Ma. Stepwise increase in susceptibility of aeolian dust accumulation appears to have a close correlation to the uplift processes of the Tibetan Plateau. The remarkable increase of aeolian dust accumulation at 3.2 Ma appears to be due to the influence of global ice volume on the East Asia monsoon. Palaeomonsoon variation during the late Tertiary as recorded in the Red Clay sequences from the Chinese Loess Plateau can be regarded as the product of a number of interacting factors, such as uplift of the Tibetan Plateau, solar radiation, global ice volume, etc. Project supported by the National Natural Science Foundation of China and the Foundation of Xi’an Laboratory of Loess and Quaternary Geology, Chinese Academy of Sciences.     

Evolution model and formation mechanism of bio-thermocatalytic transitional zone gas

As a new genetic type of natural gas exploration area, the bio-thermocatalytic transitional zone gas (BTTZG) has been highly stressed by geologists both at home and abroad. Systematic study on the generation mechanism of hydrocarbon at the transitional zone is presented. Based on simulating experiments and geochemistry analysis of the source rock with lower evolution, a hydrocarbon-forming model at the transitional zone has been established. The mechanism is proposed that under the condition of low temperature and pressure combining with extremely active structural stress and clay mineral catalysis, BTTZG is formed by de-group of soluble organic matter and polarized compositions through orthocarbon ion as well as by condensation polymerization of aromatic ring-rich insoluble organic matter. This mechanism controls the formation of BTTZG, and furthermore, BTTZG is the product of superimposition and interaction of all the factors mentioned above.
