A whole year analysis of riverine dissolved organic carbon (DOC) concentrations in the Xijiang River (XJR), South China, showed that the mean riverine DOC concentration (1.2. mg L-1) in the XJR was notably lower than the averaged value (5.75 mg L-1) of the global riverine DOC concentration in several major rivers. There is an inconspicuous monthly fluctuation of the DOC signal in the XJR, but on a semi-yearly time scale, however, the riverine DOC concentration had significant difference between hydrological seasons. The DOC level during the flood season (1.18 mg L-1) was less than that during the non-flood season (1.40 mg L-1). Owing to the concomitance of the flushing and dilution effects of the runoff during the high-water period, the variation of riverine DOC concentration with discharge in the XJR differed from that reported in many other major rivers. The DOC export flux above the city of Wuzhou was about 0.62. 106 g C km-2.yr-1. The DOC transported during the "056" Massive Flood period comprised 30.35% of the annual total, while the discharge accounted for 36.32. of the total annual flow. The characteristics in riverine DOC concentration in the XJR were attributed to the combined effect of the geomorphologic, monsoon climatic and hydrological processes as well as land-use within the drainage basin.

Geotectonica et Metallogenia 2003年第Z1期 112-119页

作者： WANG Jincao, XIA Bin, TANG Jingru (guangzhou Institute of Geochemistry, Chinese Academy of Sciences, guangzhou, GD 510640, China Institute of Geology, Central South University, Changsha, HN 410083, China)

The Linglong-Jiaojia ore-centralized district is controlled by the tectonic stress field characterized by the combination of extension and strike-slip, and the dip, dip angle, pitch and pitch angle of the ore bodies are all constrained by the dynamic conditions of the tectonics. The metallotectonic series for the ore-centralized district belong to the type of a combination of extension and strike-slip and can be subdivided into four sub-series. The ore-forming process in the brittle regime can be disintegrated into two stages, i.e., the embryonic fracture stage and the megascopic fracture stage, and ore-forming process is rather common in the ore-centralized district at the former stage. Moreover, several key structural patterns and their features were discussed and a preliminary assessment about the ore-forming prospect in this district was made in the paper.

With wax content of 1.62., heavy oil has been produced from the sandstone reservoirs of Neogene Guantao Formation (Ng1m). In the GC and GC-MS RIC profiles of its aliphatic fraction, n-alkanes are totally lost, which shows the result of heavy biodegradedation. However, the remaining trace C13-C36 n-alkanes can be still seen from its mlz 85 mass chromatogram. In addition, a complete series of C35-C73 high molecular weight (HMW) n-alkanes was detected by high-temperature gas chromatography (HTGC). The HMW R-alkane series shows a normal distribution pattern, a major peak at nC43, obvious odd-carbon-number predominance, CPI37-55 and OEP45-49 values up to 1.17 and 1.16-1.2. respectively. The present study not only has conformed the strong resistibility of HMW n-alkanes to biodegradation in crude oils as concluded by previous researchers, but also has provided some significant information on source input and maturity for the heavily biodegraded oil in the Qianmiqiao region.

近年来,基于瑞利波的全波形反演技术取得了较大进展,在接收点覆盖面积足够的情况下,该方法对横向不均匀复杂介质具有较高的分辨能力。影响波形反演精度的关键因素之一是震源子波,然而野外地震记录对应的地震子波是未知的,采用不正确的震源子波势必对反演结果产生负面影响,常规处理方法是利用合成数据进行子波校正,但子波校正需进行多次迭代,导致反演计算时间增加。为了解决这一问题,引入加窗自适应子波提取方法,从观测记录中提取与实际数据匹配较好的震源子波,将其作为初始子波进行子波校正,达到进一步优化反演结果的目的。分别采用真实子波、错误子波、错误子波联合子波校正、提取子波、提取子波联合子波校正五种子波对断层模型进行反演测试。测试结果表明:所提方法获得的子波对应的反演结果最好,错误的子波对应的结果最差;仅利用提取的子波也可以获得较好的反演效果,而采用子波提取与校正相结合的方法可以节省计算时间,进一步提高瑞利波波形反演的精度。最后通过实际数据测试进一步验证了该结论。
