丽江大研镇震灾分布和地脉动测量结果之间的相关性

丽江７．０级地震后，大研镇被毁建筑物的地理分布呈显４条条带，伤亡人员的地理分布和上述条带重合。９１个短周期地脉动测点的观测资料表明，分布在上述条带内的大多数测点，其卓越周期大于０．３Ｓ；条带外的测点，其卓越周期一般在０．１Ｓ左右。作认为卓越周期和烈度异常之间良好的相关性，是因为地脉动卓越周期和地方震的频谱之间存在良好的相关性。     

水库地震主震发生时间的预测

水利工程对水库地震的抗震设防要求事先对水为地震进行预测。预测内容包括蓄水后诱发地震的危险性（可能性、）最大震级、最大震的地占紧及不库地震对场址地震动参数的影响。除主震时间的预测外，本文第一作者都曾提出过初步的预测方法。本文认为，水库地震前震波速比异常、非线性灰色模型以及前震系列回归等方法，是预测主震时间的有前途的方法。

Turbulent fluxes over inhomogeneous landscape

Mesoscale surface turbulent fluxes over a complex terrain surrounded by oceans have been investigated using a 3-D numerical mesoscale model, under conditions with and without synoptic flows. The study indicated that under synoptically calm condition, the allocation and intensity of mesoscale surface turbulent fluxes (MSTFs) were greatly impacted by the thermally forced mesoscale circulation (TFMC) over mesoscale heterogeneous landscape. The max-imum values of sensible (Hs) and latent (LE) heat fluxes were located over the convergent zones and considerably im-pacted by the soil wetness (M), but did not depend strongly on the atmospheric background thermal stability (β0). The simulated results suggested that the sensible heat flux was closely proportional to the square of wind speed in the surface layer. By the action of synoptic flow, the allocation of LE was shifted to downwind, its intensity increased.     

Meteoric diagenesis in Pleistocene reef limestones of Xisha Islands, China

This paper focuses on a borehole, Xichen-1 well, drilled on the Chenhang Island, Xisha Islands in the South China Sea. Mineralogical, petrographic, stable isotopic and minor-element data from the Holocene to Pleistocene interval (0–179 m ) in the Xichen-1 well are discussed in detail. The 400-m-long core is divisible into four mineralogical facies: a high-Mg calcitic aragonite facies (0–16.91 m, Holocene), an aragonitic low- Mg calcite facies (16.91–30.60 m, Late Pleistocene), a low- Mg calcitic facies (30.60–179 m, Middle-Early Pleistocene) and a low- Mg calcitic and dolomitic facies (179–400 m, Early Pleistocene–Late Miocene). The Holocene section has much higher whole-rock δ¹⁸O and δ¹³C values and Mg and Sr content than the non-dolomitized Pleistocene limestones (16.91–179 m). The 16.91–165 m interval is characterized by a relatively invariant oxygen isotopic composition and very heterogeneous carbon isotopic composition. Between 165 and 179 m, there is a positively correlated increase of whole-rock δ¹⁸O and δ¹⁸C with depth, and Mg content also shows a gradual increase with depth. Petrographic data demonstrate that the Pleistocene reef sequence has been extensively affected by meteoric waters. We conclude that the Late Pleistocene section (16.91–30.60 m) and the Middle-Early Pleistocene section (30.60–165 m) have suffered incomplete and complete meteoric diagenesis, respectively, and that the Early Pleistocene interval (165–179 m) was diagenetically altered in a meteoric–marine mixing environment.

对煤中锗矿化若干问题的思考——以临沧锗矿为例

本文在综述煤中锗矿化国内外研究现状的基础上，以临沧锗矿为例，深入讨论了在煤系地层中形成超大型独立锗矿床的特殊条件。结果表明，煤是锗成矿极有利的围岩，煤能否富集锗主要取决于有无富锗流体与煤相互作用。     

遥感技术在化工环境保护中的应用

遥感技术获取的可见光、红外及微波信息，可以对化工企业及化学矿山环境污染（水、粉尘、大气、废渣污染等）及环境地质灾害（滑坡、泥石流、地面塌陷等）进行实时动态监测，并可获得较高的社会经济效益，达到地面环保及常规环境地质工作难以达到的效果。特别是对重点大中型化工企业及化学矿山建立环境遥感信息动态监测系统，可以为国家决策部门及时准确地提供环境治理和改造的依据。
