煤层上覆地层含水不均匀性电法探测的可能性

煤田上覆岩层中含水直接对煤层的开采构成威胁，本文先从理论上阐述了电阻率勘探可以探测煤层上覆地层含水不均匀性的可能性，然后用简单的断层型薄层含水模型的CSAMT正演模拟结果展示出：地下900m深处，尽管只有20m厚的的含水岩层，但在电阻率剖面上该薄层的反映具有非常明显的特征，从理论上和数值模拟实例说明，一定深度内一定厚度的薄层含水性的电阻率法探测是可能的。

秦岭镇-旬地区微细浸染型锑金矿床成矿条件及其找矿前景分析

镇（安）旬（阳）地区锑金矿化分布，与其区域地质地球化学因素，陆源断陷盆地沉积岩相变化，后期构造作用密切相关，认为镇旬地区为扬子与华北板块边缘对接过渡活动带，形成局部扩张断陷沉积盆地环境。海底同生断裂的发育，使盆地中心局限台盆环境造成陆源物质、内源组份和深部物质的混生，以及为深部含矿热液上升提供通道；在后期脆－韧性剪切变形构造叠加，地下热卤水循环改造作用，形成层控式细脉浸染型锑金矿床。该地区锑金成矿物质来源丰富，沉积构造环境优越，后期控矿构造发育，显示了潜在的细脉浸染型锑金矿床的找矿前景。

The phytoplankton of some saline lakes in Central Asia

The Aral Sea, Lake Balkhash, and Lake Kamyslybas are closed lakes in Central Asia. They range from oligosaline to metasaline. The salinity of the Aral Sea has increased by more than 30 g L⁻¹ since widespread irrigation began in its catchment area. Few studies of the phytoplankton have been conducted on these lakes since extensive irrigation started. The investigation reported here compares the flora of phytoplankton in these saline lakes. In the Small Aral Sea, phytoplankton density gradually decreased with increasing electrical conductivity (EC) (∼ salinity), but there was no such relation in Lake Balkhash and Lake Kamyslybas. In the Aral Sea, Dinophyceae and Bacillariophyceae were frequently observed in most areas of high EC value, and Cyanophyceae were most conspicuous in the area of medium and lower EC values. In Lake Balkhash, Cyanophyceae were most conspicuous, but Chlorophyceae were also noticeable. Most Cyanophyceae in Aral Sea formed filaments with heterocysts. The distinct characteristic of the phytoplankton of the Lake Balkhash was that all dominant species form colonies covered with a gelatinous film. Siliceousplankton diversity gradually decreased with increasing EC values in the Aral Sea and Lake Balkhash.
