安徽宁国山口村紫砂用黏土岩矿地质特征与成矿探讨

江苏宜兴制陶用黏土岩矿日益枯竭,上等紫砂矿已逐渐关闭开采,市场上的紫砂矿供不应求。安徽省宁国市山口村紫砂用黏土岩矿的赋矿层位为泥盆系、石炭系,与江苏宜兴黄龙山地区紫砂矿具有相同的赋矿层位,初步烧制了紫砂壶,具有进一步开发利用价值,填补了安徽省紫砂原料产地的空白。通过系统勘探,该区大致查明砖瓦用黏土岩矿(333)矿石量2390.87万t,陶器用黏土岩矿(333)矿石量1088.94万t、(334)矿石量110.64万t,紫砂用黏土岩矿(333)矿石量419.26万t,矿床规模达到大型。结合地质工作成果,对山口村紫砂用黏土岩矿地质特征、成因进行了分析,并对紫砂用黏土岩矿的工业性能指标进行了分析,对于该区紫砂用黏土岩矿勘探及开发利用有一定的参考价值。

Analysis on Economic Performance of Electrical Equipment Industry in 2010

In this paper the analysis is presented on the economic performance of the electrical equipment industry in 2010.Substantial increase was seen in both the economic aggregate indices such as production and sales,and economic efficiency indices such as profits.Increase of indices that reflect foreign trade situation of the industry,such as import volume,export volume,gross import and export volume,and export delivery volume were prominent in particular.The industry has completely stepped out of the "negative growth" predicament in 2009,comprehensively outperformed the level in 2008,and recovered true growth.The economic situation of the electrical equipment industry in 2011 is also predicted in this paper.
