广西老厂铅锌矿床地质特征及其成因探讨

本文是在专题研究基础上,探讨广西老厂铅锌矿床地质特征和矿床成因。该矿床位于海洋山复式背斜南段的老厂穹窿构造核部,铅锌矿化受构造、地层和岩性控制。矿体呈脉状,产于NE向组张扭性断裂构造中;围岩为寒武系白云岩,板岩、砂岩;矿石类型以锌为主,矿物成分简单,以闪锌矿、方铅矿与石英、白云石为主,具充填、交代矿石结构、构造,矿石平均品位含Zn9.94%、Pb1.50%;围岩蚀变主要为硅化、绢云母化和碳酸盐化。据地层岩石元素丰度值、稀土元素配分和稳定同位素数据、资料,探讨了成矿物质来源于围岩,热液主要来自大气降水。因此,认为本矿床实属产于寒武系轻变质岩中的层控矿型大气降水热液铅锌矿床。

在7月16目召开的全国地质勘查管理座谈会上，国土资源部副部长汪民指出，按照我国法律法规，探矿权两级管理、采矿权四级管理，不存在初审问题。     

技术要素按贡献参与分配的探讨

分析了技术要素按贡献参与分配的基本依据和存在问题，提出了技术要素按贡献参与分配的建议：1．在企业分配领域，鼓励技术要素以多种形式参与收益分配，鼓励体制创新，推进技术股份化。2．在政府分配领域，政府财政科技投入比例与其科技发展对经济贡献增长率挂钩，科技财税政策与产业政策、税源经济吻合，营造科技奖励的软环境。3．在社会分配领域，充分发挥技术评估部门和行业管理部门的作用，对进入技术市场的技术的成熟度和科技含量进行有效的测试和监管，保证技术商品的品质；技术交易当事人应具诚信态度和法制观念；重视中介的作用，把技术市场搞活。     

The Geologic Time Scale and the Italian stratigraphic record

The construction of the Geologic Time Scale (GTS) is a titanic scientific challenge that has been under way for two centuries and will require much dedicated effort in the future. Italy preserves a paramount stratigraphic record of Mesozoic and Cenozoic marine sediments that have been significant in the development of the modern GTS. The Italian stratigraphic record has been histori-cally important in introducing and defining the standard Chronostratigraphic Units (CUs) of the Neogene and Quaternary. Pelagic successions from Northern Apen-nines and Southern Alps have been used in the seventies for integrating the late Cretaceous-Paleogene Geomag-netic Polarity Time Scale (GPTS) with planktonic microfossil biostratieraohv and standard CUs. This was a major contribution to the construction of a new gener-ation of GTS based on integrated magnetobiochronol-ogy. The middle Miocene to early Pleistocene marinerecord from Sicily and southern Italy has been funda-mental for establishing the recently developed Astro-nomical Time Scale (ATS). In prospect, there are many potentials still to be exploited in the Italian marine stratigraphic record for implementing the GTS by defin-ing GSSPs of various CUs, improving magneto-biochronology and extending downwards the ATS.
