琼东南盆地多边形断层在流体运移和天然气水合物成藏中的作用

 多边形断层是由未固结沉积物脱水使得体积收缩而在平面上呈现多边形形状,且具有微小断距、分布密集的张性断层。在琼东南盆地深水区的中新世—上新世地层中,利用三维地震相干切片可以发现小规模流体运移通道——多边形断层。同样在二维高分辨率地震剖面上也能发现多边形断层、底辟和同相轴下拉的管状构造,距海底双程走时250ms和300ms位置存在强的似海底反射层（Bottom Simulating Reflector,简称BSR）。利用约束稀疏脉冲反演和地震属性分析表明,多边形断层上部地层的管状构造和模糊反射区为低声波阻抗异常和低频率异常,BSR上为高声波阻抗和高频率异常。多边形断层、管状和底辟构造破坏了琼东南盆地裂后热沉降阶段巨厚的泥岩地层的封闭性,使大量流体垂直和近似垂直向上运移,为天然气水合物形成提供了充足气源。

DYNAMICS OF THE ZONAL ASYMMETRIC STRUCTURE OF ARCTIC OSCILLATION

The Arctic Oscillation (AO), though basically is a zonal symmetric phenomenon, also shows zonal asymmetric variation. The dynamics of this zonal variation is considered here from the point of view of the planetary propagation on the earth sphere. Based on the linear barotropic vorticity equation, the planetary wave ray path is calculated in the winter January. It shows that NAO(North Atlantic Oscillation),AO and North Pacific could be linked through the planetary wave propagation, which acts as the atmospheric bridge. The zonal symmetric and asymmetric structures both have association with these Rossby wave activities.

Functional analysis of ZNF85 KRAB zinc finger protein, a member of the highly homologous ZNF91 family

We previously identified the ZNF85 (HPF4) KRAB zinc finger gene, a member of the human ZNF91 family. Here, we show that the ZNF85 gene is highly expressed in normal adult testis, in seminomas, and in the NT2/D1 teratocarcinoma cell line. Immunocytochemical localization of a panel of beta-Gal/ZNF85 fusion proteins revealed that ZNF85 contains at least one nuclear localization signal located in the spacer region connecting the KRAB domain with the zinc finger repeats. Bacterially expressed ZNF85 zinc finger domain bound strongly and exclusively to DNA in vitro in a zinc-dependent manner. The KRAB(A) domain of the ZNF85 protein and of several other members of the ZNF91 family exhibited repressing activity when tested in Gal4 fusion protein assays. The repression was significantly enhanced by the addition of the KRAB (B) domain, whereas further addition of other conserved regions had no effect. The ZNF85 KRAB(A) and (B) domains in vitro bound several nuclear proteins that might constitute critical cofactors for repression.
