地壳演化与成矿作用——以川滇地洼系“四层楼”铜矿床序列为例

提出川滇地洼系“四层楼”铜矿床序列的形成与陆壳演化的成生联系,是与本区陆壳由前地槽—地槽—地台—地洼演化各阶段与之相匹配的成矿作用的产物.与此同时,并总结了本区“四层楼”铜矿床序列的成矿作用具有明显的继承性、新生性、旋回性及层控性四大特点和多因复成矿床的成矿模式.     

鱼类生长激素的体内代谢、分泌调控和作用机制研究的进展

主要对１９８３－１９９６年间关于鱼类生长激素的体内代谢、分泌调控和作用机制的研究进展予以综合评述。通过鱼类划性放射免疫测定法的建立和体风代谢动力学研究，证实，外源生长激素在鱼体内不会产生积累。鱼类生长激素的分泌调控受下丘脑分泌的生长激素释放因子（ＧＨＲＦ）和释放抑制因子（ＳＲＩＦ）的双重；促性腺激素释放激素（ＧｎＲＨ）、雌二醇（Ｅ２）、促甲状腺素释放激素（ＴＲＨ）和神经肽（ＮＹＰ）对鱼类生长激素的     

华南海西—印支期成矿地质背景

华南海西—印支成矿期内,成矿序列完整,类型齐全,矿种繁多,为其它成矿期所莫及。沉积矿床需要稳定的地质背景,层控矿床形成的较有利的地质背景是稳中有动。     

滇西潞西上芒岗卡林型金矿

上芒岗金矿赋存于二叠系沙子坡组碳酸岩和侏罗系勐戛组下段砂岩、灰岩中,明显受上芒岗断裂控制,与美国模式卡林型金矿极为相似,具有相同的物质来源和成因模式。上芒岗地区具有广阔的深部找矿前景。

团结沟金矿床地质模型

矿床地质模型是综合信息找矿模型的基础。本文从团结沟金矿床地质特征入手，分析了团结沟金矿床的控矿地质条件，探讨矿床的成因，进而建立起团结沟金矿床的矿床地质模型。     

山东龙口大顶金矿地质特征及找矿方向

重点介绍大顶金矿区的地质特征及区内主要矿脉体(36号矿脉群)特征，同时，对控矿因素作了一定的分析，初步总结了36号矿脉群在双顶矿段北东缘的成矿规律，指明了本矿区的找矿标志及下一步的找矿方向。     

The neoliberalization of ecosystem services: wetland mitigation banking and problems in environmental governance

Wetland mitigation banking is an American neoliberal environmental policy that has created a functioning market in `ecosystem services', commodities defined using the holistic measures of ecological science. The development of this market is discussed as a project of environmental governance, defined as the nation-state's regulation of ecological relations within its territory towards stabilizing capitalist relations of power and accumulation. I argue that the wetland banking industry serves as a bellwether that presages problems that other strategies of neoliberal environmental governance will experience. Ethnographic, economic and ecological data from the Chicago-area wetland banking industry inform a discussion of two major obstacles to neoliberal strategy: the problem of relying on ecological science to define the unit of trade, and the problem of aligning the somewhat independent relations of law, politics, markets and ecosystems across an array of spatial scales. Theoretical guidance is sought from recent work on `social natures' and from the Regulationist approach to institutional political economics.     

Uncertainty and asymmetric information: An overview

This paper provides an overview of the literature on fisheries economics related to uncertainty and asymmetric information. It is argued that uncertainty is relevant in connection with present and future stock sizes and prices, while asymmetric information is important for cost functions, catches, catch per unit of effort, and effort. The literature on uncertainty and asymmetric information can be seen as providing the basis of an argument for using taxes in fisheries management. It is, therefore, surprising that over 55 countries regulate their fisheries with individual quotas, while taxes are not used at all.     

成矿模式研究的几个问题

成矿模式是当代矿床学研究的重要内容和发展方向，是矿床地质科学在描述性基础上发展到高度理论性的必然产物。成矿模式是在区域成矿学研究和典型矿床研究的基础上建立的，它不仅有助于人们深化对矿床特征和矿床成因的认识，而且对矿产预测和勘查工作具有日益重要的指导作用。作者根据成矿模式的概念和研究成果，提出了新的矿床分类设想，并就成矿模式与成矿系列的关系等问题进行了有益的探讨。
