完善我国现行《矿产资源法》的构想

为了使我国现行的《矿产资源法》的修改与完善能更加与我国的矿业经济相适应。试从：（1）理顺矿产资源所有权和土地所有权关系;（2）完善矿业权市场流转的规定;（3）完善矿业环境保护与治理的规定;（4）建立权利金制度,合理征收资源税与矿产资源补偿费;（5）完善小型矿山采矿行为的规定;（6）制定限制外商投资我国战略性矿产资源的规定;（7）制定建立战略性矿产储备制度的规定等几方面,对其完善的构想进行论述。以供相关人士参考。     

地-井TEM向量交会技术的实现和应用效果

这里介绍的地-井TEM向量交会法是一种地-井TEM资料半定量解释方法,通过采用异常分离技术从实测资料中提取出纯异常场,运用地-井TEM的纯异常响应进行向量交会,从而达到快速、有效地确定井旁盲矿体的深度、方位及矿体距钻孔距离。     

Refinement of a lunar FeO mapping method

Clementine UVVIS and NIR data from the lunar sampling sites (totaling 46 sampling sites) were processed and used to refine the iron determination method of Le Mouéic et al. (2000, 2002). We found that about 21 sampling sites are unsuitable to Le Mouéic et al's spectral parameters ("slope" and "depth l") because their 1500 nm filter could not be used as spectral parameters' right shoulders and to evaluate the depth of the 1-μm absorption feature accurately. We used the rest 25 sampling sites to refine the method developed by Le Mouéic et al. (2000, 2002 ) and obtained our own equation of FeO content determination. We tested our own equation, and the results are satifactory. In our work we also acquired some useful experiences in scientific applications of our own dataset of the Chang'E-1 mission.

基于壳聚糖席夫碱类衍生物修饰电极测定食品中的亚硝酸根离子

利用水杨醛对壳聚糖进行改性,合成壳聚糖席夫碱类衍生物(S-CTS),将其滴涂在玻碳电极表面成膜。用循环伏安法研究了该修饰电极对NO2-的电催化作用。以0.1mol/LpH4.5的B-R缓冲溶液为底液,还原峰电流与NO2-浓度在0.20～81mg/kg范围内呈良好的线性关系,相关系数为0.9899,检测限达到2.8×10-7mol/L。用于样品测定,结果较为满意。     

新疆及周边国家铜矿产资源战略分析

介绍了世界铜矿床主要类型及其分布特征,并对我国新疆及周边国家铜矿产资源进行调查,结合我国铜资源现状及供需情况分析,说明我国铜矿产资源相对比较贫乏.目前正面临着铜需求快速增长,而铜资源短缺的紧张时期,如何保证铜资源的可持续发展是一个很现实的问题.这就要求我们一方面加强同周边国家和地区的铜矿产资源的开发与合作,另一方面着重勘探与开发我国新疆的铜矿资源.     

矿物材料应用于香烟过滤嘴降害的研究现状与展望

总结了近几十年来包括活性炭、沸石、蒙脱石、海泡石、麦饭石、凹凸棒石、氧化铝、氢氧化钠、明矾、纳米材料等矿物材料作为卷烟滤嘴添加剂以去除烟气中有毒有害物质的研究和实验应用及效果。实验结果和市场调查表明,活性炭是减少卷烟危害最快、香烟市场应用增长最快的过滤嘴添加剂。从降低卷烟有害成分的比例和成本等综合因素来看,铝硅酸盐类滤嘴和多材料复合滤嘴亦有很好的应用前景和市场需求,应积极进行研制。     

Three-dimensional sedimentary architecture of Quaternary sand and gravel resources: a case study of economic sedimentology (SW Germany)

Quaternary sands and gravels form important, yet often highly heterogeneous economic deposits. Detailed 3-D analysis of the sedimentary structure and stratigraphy of these deposits allows for an accurate estimation of exploitable material. This paper presents a case study in SW Germany reconstructing the 3-D distribution of glacial sediments based on a high-resolution, process-orientated sedimentary facies classification and lithostratigraphy integrated within the geo-modelling package gOcad. Situated along the maximal ice-extent of the Rhine glacier during the last glaciation, the study area is characterised by a morphologically prominent terminal moraine and its associated sandur, which form the stratigraphically youngest sediments of a glacial basin, partially exposed in two gravel pits. These outcrops helped to reconstruct the complex sedimentary architecture of the northern part of the glacial basin. The regional analysis is based on core data, as well as geoelectric and geomagnetic surveys. All data were integrated into km-scale, high-resolution geological 3-D models, depicting the large-scale dynamics of multiple glacier advances and retreats during the Early to Late Pleistocene. These models allow quantifying the thickness and volume distribution of exploitable sandy gravel and help to evaluate the occurrence of non-exploitable interbedded diamicton horizons. The high quality and quantity of gravels particularly north of the terminal moraine classifies the investigated area as very prospective for raw materials exploitation in the future.     

Mineral Components, Texture, and Forming Conditions of Hydrothermal Chimney on the East Pacific Rise at 9°-10°N

To characterize the hydrothermal processes of East Pacific rise at 9°-10°N, sulfide mineral compositions, textural, and geochemical features of chimney ores were studied using ore microscope,scanning electron microscope, X-ray diffraction analysis, and electron microprobe techniques. Results show that there are three mineral assemblages for the hydrothermal chimney ores, namely：（i） anhydrite ＋ marcasite ＋ pyrite, （ii） pyrite ＋ sphalerite ＋ chalcopyrite, and （iii） chalcopyrite ＋ bornite ＋ digenite ＋ covellite. Mineral assemblages, zonational features, and geochemical characteristics of the ore minerals indicate that ore fluid temperature changed from low to high then to low with a maximum temperature up to 400 ℃. The chimney is a typical black smoker. The initial structure of the chimney was formed by the precipitation of anhydrites, and later the sulfides began to precipitate in the inner wall.
