中条山区前寒武纪铜矿床地质历史演化及成矿年代

中条山区铜矿床是在中条古裂谷地质构造环境中演化形成的。本文从涑水杂岩期－绛县期－中条期－西阳河期等不同时代地质历史演化，分别探讨了中条山区不同类型铜矿床时空分布和成因上的内在联系。它们早期形成的矿源层受不同时代的层位和岩性控制，但在后期的２０００～２１００Ｍａ和１８００～１９００Ｍａ较大规模的构造－热事件，对不同类型铜矿床进行了叠加和改造，使铜质进一步富集，最终形成工业矿床     

盐水体系热力学平衡态和非平衡态相图

在对海水Ｎａ＋、Ｋ＋、Ｍｇ（２＋）／／ＣＩ－、ＳＯ４（２－）－Ｈ２Ｏ体系在２５℃时或室温条件下采用合成复体法得到的平衡溶解度相图，蒸发结晶方式得到的蒸发相和采用过饱和溶液封闭静置结晶法得到的过饱和区相图进行对比分析，把它们划分成两种类型，热力学平衡态和非平衡态相图。对这两类相图关系进行探讨基础上认为，热力学非平衡相图主要是由于同一种盐在水溶液中是双粒子形式共存而引起过饱和溶解度现象所致。

Analysis Method for Predicting Strain in Interior Beds and Sub-Resolution Faults from Area Balance Theory in Extensional Basins

Extensional basins include mainly grabens and half grabens displaced along a lower detachment. Based on area balance theory, there is a linear relationship between a height of regional and the lower detachment h on the outside of the basin and “lost area S“ from the regional in the basin. The pre-growth beds above lower detachment are of the same extensional displacement so that an “S-h diagram“ can be used to determine the depth to lower detachment and to calculate the total extensional displacement of the beds above the lower detachment. The extensional displacement is dominated by the heave of various scale normal faults. The displacement of obvious faults can be immediately figured out from the measured bed-length. The requisite extension calculated by area balance is the layer-parallel strain, which could be accommodated by displacement on sub-resolution faults. Accordingly, the layer-parallel strain can help us predict the magnitude and distribution of sub-resolution faults on the basis of analysis of the structural style and rheological behavior.     

Molecular analyses of bacterioplankton communities with highly abundant Vibrio clades: a case study in Bohai Sea coastal waters

We investigated the bacterioplankton abundance, community composition and the associated Vibrio clades of natural seawater in Bohai Sea coastal waters. Seawater samples (10 L in triplicate) were collected at 0.5, 3, and 5 m depths near the coastal aquaculture zone of the Bohai Sea on May 12, 2016. Real-time PCR and 16S rRNA gene amplicon high-throughput sequencing methods were employed by which 485 operational taxonomic units (OTUs) at a 97% sequence similarity level were generated. Gammaproteobacteria, Alphaproteobacteria, and Bacteroidetes were the most abundant groups, accounting for 49.5%, 23.5%, and 18.9% of the total assemblage, respectively. Obvious variations in Pseudoalteromonas, Vibrio, and Octadecabacter , which were the most abundant genera, could be observed among diff erent samples. Notably, the results of Vibrio -specifi c real-time PCR indicated that Vibrio had extremely high 16S rRNA gene copy numbers. The 16S rRNA gene sequencing results across all the samples also indicated that they occupied a large proportion of the total assemblage. Both the alpha diversity and major bacterioplankton group Pseudoalteromonas had significant correlations with the concentration of PO4^3-. Overall, studies on bacterioplankton communities with highly abundant Vibrio clades can provide interesting insight into the microbial function and health assessment of the Bohai Sea coastal ecosystem.
