“入世“给地质勘查业带来的机遇与挑战

我国"入世"后,外国跨国公司必然会进入我国的地质市场.对比,本文指出了国内地勘单位与跨国公司相比,在技术力量、资本和管理水平等方面存在的问题,以及它们的介入所带来的不利影响和机遇,针对这些问题提出了具体的对策及所采取的措施.     

21世纪矿业应向后工业发展势态倾斜--适者生存和可持续发展

“后工业”（post-industry)是知识经济或曰“新经济”的发展时代。这个时代的自然资源和一般劳动力资源,包括矿产资源在国民经济和社会发展中的基础地位逐渐为知识产权、市场网络、信息、创新环境等后天获得性资源,以及为创新人才的新“认知”（recognized intellect,RI)所代替。然而,据矿产资源分布及其成矿既具有一定的全球统一性又有区域的特殊性,以及不同国家（地区）对矿产资源勘查程度的不均衡性,特别是矿业活动与其他产业性质的不同,如何能按不同国家（地区）的具体发展状况,做好21世纪矿业向“后工业”发展势态的倾斜,达到适者生存和矿业可持续发展的目标是当代探讨的重大问题。在概括阐述了21世纪矿业发展势态、矿业活动特点及其自然属性的基础上,提出了矿业可持续发展的地质勘查和矿业活动决策支持系统的模拟,以及对当前紧缺铜矿资源可持续发展的新“认知”。

A preliminary case study of potential ceramic raw materials in the Aileu area of Timor Leste

The newly independent country of Timor Leste is located in the eastern half of Timor Island (Indonesian archipelago). Geological studies of the country’s mineral resources and extractive activities are practically non-existent. There is evidence of the exploitation of ceramic raw materials at outcrop level and two small brick kilns, nowadays inactive, in the Dili and Aileu areas. Near Aileu, there are light-coloured silt-rich deposits, interpreted as overbank deposits, interbedded with ancient river terraces (post-Pliocene) overlying metamorphic bedrock. These sediments are the subject of this study, which encompassed geological mapping and preliminary characterisation. Tectonically, the area is a graben, preserving alluvium and colluvium deposits. Five channel samples representative of the silt-rich deposits were collected. Semi-quantitative mineralogical analysis shows that the samples are made of illite, quartz and kaolinite clays, with accessory illite/vermiculite interstratified minerals and K-feldspar. The chemical data show agreement with the estimated mineralogical composition. The grain size distribution points to a silt-dominated assemblage. Most samples have a satisfactory extrudability but deficient moulding properties. After firing, the sampled raw materials form a final product with possible ceramic capability for whiteware production.     

甘肃矿业的经济社会支撑度分析

甘肃是我国矿产资源相对丰富的省区之一,矿种齐全,分布面广,部分矿种的探明资源储量大,有色和贵金属矿产具有比较优势。在经济持续快速发展的新时期,矿产资源的经济社会支撑和保障能力是需要认真分析的战略问题。本文从甘肃实际出发,以统计数据为依据,分析了矿产资源对甘肃经济社会发展的支撑能力,提出了矿产资源开发和可持续利用的政策措施。

Maquiladora Myths: Locational and Structural Change in Mexico's Export Manufacturing Industry

Trends in location, labor force, and procurement practices in maquiladoras are examined using recent data sources. A growing proportion of maquiladoras are selecting interior locations, south of the borderlands. Once dominated by young women, the labor force is rapidly approaching gender parity. While far below prevailing rates in the United States, maquiladora wages are comparable with equivalent manufacturing sectors in Mexico. Majority ownership of maquiladoras is split almost evenly between Mexico and the U.S., however, maquiladoras have failed to develop domestic sources of materials and parts and remain dependent on imported material inputs. As the North American Free Trade Agreement is phased in, the regulatory environment of maquiladoras will change but their role as low cost assembly specialists will persist.     

Factor analysis of trends in energy and metals production and consumption in developed and developing countries

This paper presents a methodology used to combine energy and mineral market variables between Less Developed Countries (LDCs) and Developed Countries (OECD) over the past 24 years (1966–1990). LDCs include all countries, except OECD and central planned economies (CIS) and other countries in Eastern Europe. This period permits a comprehensive view of the impact of the energy crisis and the changes in economic growth patterns, correlated with changes in trends of production and consumption of energy and metals in both country blocs. This complex relationship was evaluated by a factor model of consumption and production variables using the aluminum, copper, lead, and zinc industries. The following variables are used in the factor model: export dependence, geographic concentration of mining production, geographic concentration of refined demand, geographic concentration of refined production, import dependence, refined demand growth, stability of demand, income elasticity of refined demand, price stability, intensity of use, and intensity of energy. The model for all commodities shows that the factor scores projections for LDCs and OECD blocs depicted a clearly divergent trend after the two oil shocks (1973–1979), when the intensity of energy variable presents high loading in the factor. The results are in substantial agreement with findings that the demand for energy, as well as for metals, is growing more rapidly in LDCs than OECD.
