青藏高原钠硼解石的物理化学特征

本文从西藏扎仓茶卡和青海大小柴旦盐湖现代沉积的硼酸盐矿物中．纯化得到符合理论化学组成的纳硼解石．获得它的红外光谱图，Ｘ射线粉末衍射圈和ＤＳＣ、ＤＴＡ热分析图，讨论了热行为．给出了它在水中的溶解度和热力学函数。     

东山峰背斜寒武系地层中硼锂元素的指相意义

东山峰背斜寒武系地层分布区内，Ｂ，Ｌｉ元素的水系沉积物测量平均值分别为１７７．７８×１０－６、２２０．０×１０－６，衬值分别为２．３２、５．０７，Ｒｂ／ｋ比值为０．００６２。这些地球化学特征具典型的指相意义，反映出本区在早寒武世晚期至中、晚寒武世期间为一高盐度、强蒸发的泻湖相沉积环境，可与现代盐湖相环境类比。     

硅硼镁铝矿－柱晶石－电气石组合在南极的发现

硅硼镁铝矿、柱晶石和电气石组合产于东南极拉斯曼丘陵，三种矿物相互接触并表现出特定的顺序：电气石（Ｔｒｎ１）→硅硼镁铝矿→电气石（Ｔｒｎ２）→柱晶石→电气石（Ｔｒｎ３），表明其产出是受Ｂ２Ｏ３、Ｈ２Ｏ活度的时间演化而不是空间变化所控制。这一组合的出现对于变质作用环境及过程中组分性质是一个很好的限定     

浙东南层状火山熔岩型铀矿溶浸地质条件研究

本文根据“溶浸找铀工作”的要求，广泛收集了“浙江南６６０铀矿田”赋矿层状熔岩的特征、铀矿化特征，综合分析了该矿田的溶浸地质条件及其在该区开展“溶浸找铀工作”的可行性，指出了开展“浙江南层状火山熔岩型铀矿溶浸区调工作”的必要性。     

Spectroscopic Study of Natural Diamonds in China

It has become clear in recent years that the important substitutional impurities in diamond are nitrogen,hydrogen and boron(Bibby,D.M.,1982).The physical and chemical properties of diamond are determined by the content and form of occurence of nitrogen based on which diamonds are generally classified.The well-known experiments concerning the mutual transformation of the forms the origin of diamond.by Evans.T.Et al.(1982) have provided a theoretic basis for the origin of diamond.Since 1979,spectroscopic investigation of natural diamonds from different areas in china has been carried out using UV-visible and IR spectrophotometer,EPR and cathodoluminescence techniques.We have conducted the classification of natural cathodoluminescence techniques.We have conducted the classification of natural diamonds in China and studies on the forms of nitrogen and hydrogen,the radiation damage and their geological implications.Spectroscopic characteristics of natural diamonds in china and their geological implications are discussed in this paper.
