长江中下游地区若干铁铜（金）矿床中块状及脉状钙质夕卡岩的氧锶同位素地球

报道了狮子山等若干夕卡岩型矿床和一个规模较大的无矿化夕卡岩脉中夕卡岩的Ｏ、Ｓｒ同位素研究结果。绝大多数夕卡岩的δ＾１８Ｏ值介于５．０和８．５之间，低于本区闪长岩类岩石及沉积碳酸盐岩的δ＾１８Ｏ值；     

Mineralization Zoning in Yindongzi—Daxigou Barite—Siderite,Silver—Polymetallic Deposits in the Qinling Orogen,China

The Yindongzi-Daxigou strata-bound barite-siderite,silver-polymetallic deposits discovered in the Qinling orogen are hosted within flysch facies in a deep-water fault-controlled basin on the passive northern margin of the Qinling microplate.The orebodies occur in a series of hydrothermal depositonal rocks.Mineralization zoning is characterized by Fe-Ba←Ba-Cu←Pb-Ab→Cu-Ag→Pb→Au.This is obviously a gradational transition mineralization from ventproximal mineralization to more distal mineralization.In this gradational transition between Chefanggou and Yindongzi,vent-proximal mineralization consists of silver-polymetallic orebodies(Pb-Ag),which is the center of hydrothermal mineralization.The Chefanggou Ba-Cu ore district in the west and the Yindongzi Cu-Ag ore district in the east represent vent lateral mineralization.Distal mineralization in the west is represented by the Daxigou Fe-Ba ore district while distal mineralization in te east is represented by the Pb ore district.Thick massive,laminated barren albite chert and jasperite,sometimes with minor silver-ploymetallic mineralization of commercial importance,and pyritization in rocks feature more distal mineralization.Geochemical anomalies of Au-As associations are found in ankerite phyllite and muddy sandstone.Actually,Au deposits are dominantly controlled by the late brittle-ductile shear zone.     

桐柏大别山区优势矿产资源综合开发利用研究

桐柏大别山区不仅矿产资源丰富，而且品种多，储量大，地域组合良好，特别是以化工原料，建材原料，贵重金属，石油和天然气为主的优势矿产资源，在全国占有较为重要的地位。本文在对桐柏大别山区矿产资源深入研究和对市场前景分析预测的基础上，提出了综合开发利用桐伯大别山区优势矿产资源，以资源为依托，建立建材，化工，石油加工等区域工业支柱的对策和加速矿产资源开发利用的措施。     

鞍—本地区条带状铁建造中硅铁矿物分异反馈及生长动力学演化

自组织过程中矿物的竞争性颗粒生长模型与颗粒生长动力学演化方程是鞍－本地区条带状铁建造（ＢＩＦ）在变质分异作用过程中硅铁分异形成硅质矿物条带与铁矿物条带的生长反馈系统及矿物竞争性颗粒生长的动力学演化过程，竞争状态的表面扩张担负起了Ｏｓｔｗａｌｄ成熟律作用，使系统向减少颗粒数但加大颗粒体积的状态演化，导致了矿物相的成层分异。     

铁法盆地西部矿区16^#煤聚积环境背景及聚煤特征

铁法盆地西部矿区１６＾＃煤是在冲积扇前网结河－湖缘三角液－湖泊环境组合背景上大面积泥炭沼泽化而形成的。聚煤环境有湖缘三角洲平原泥炭沼泽，湖滨泥炭沼泽、冲积扇前湿地泥炭沼泽和网结河湿地泥炭沼泽。其中，湖滨和湖缘三角洲平原泥炭治泽垂向叠加地段构成北部富煤带的主体，冲积庐前湿地泥炭沼泽形成了南部富煤带的主体。     

等离子体质谱铼—锇同位素测年法研究及其应用

采用同位素稀等离子体质谱铼－锇同位素测年法，测定了中国的几个钼矿床和铜镍化物矿床成矿年龄。Ｒｅ和＾１８７Ｏｓ的空白值分别为７０和１０ｐｇ。年龄测定精度在３％左右。
