基于构造—地层学的隐蔽圈闭预测——以松南十屋断陷深层为例

综合运用高精度层序地层学、构造一地层学方法,认为十屋断陷深层发育的各类隐蔽圈闭是下一步勘探工作的重要目标。同时,由于构造对沉积的控制作用,在断陷内部不同的构造部位具有不同的隐蔽圈闭分布特征。十屋断陷西部皮家地区、北部张家屯一八屋地区位于油气主要运移指向区,分别由断裂坡折带和以挠曲型褶皱为特征的弯折带控制的储集砂体十分发育,盖层及保存条件也十分优越,是深部原生岩性、地层油气藏最有利的勘探目标区带。

Sequence analysis and quantitative detection of Norwalk-like viruses in cultured oysters of China

We isolated 4 Norwalk-like viruses (NLVs) contaminated oysters from 33 Chinese oysters collected from local commer-cial sources of Shandong Province. After amplification of the RNA-dependent RNA polymerase (RdRp) region of NLVs genomes with RT-PCR, the open reading frame 1 (ORF1) of the RdRp was sequenced and subjected to multiple-sequence alignment. The re-suits showed that NLVs in the four isolates belong to genogroup Ⅱ. The sequence comparison showed that the similarity between four Chinese oyster isolates were higher than 99.0%, which indicated that NLVs prevalent in close areas have high homogeneity in genome sequences. In addition, the most conserved sequences between diverse NLVs were used to design primers and TaqMan probes, then the real-time quantitative PCR assay was performed. According to the standard curve of GII NLVs, the original amounts (copies) of NLVs in positive patient's fecal isolate, positive Japanese oyster isolate, and the Chinese oyster isolate were 8.9×108, 1.25×108 and 4.7×101 respectively. The detecting limit of NLVs was 1×101 copies. This study will be helpful for routine diagnosis of NLVs pathogens in foods and thus for avoiding food poisoning in the future.

辽西金羊盆地南部髫髻山组陆相火山岩及旋回层序划分

辽西金羊盆地（金岭寺－羊山盆地）南部髫髻山组陆相火山岩发育,为一套以中性为主的基性、中基性、中性火山岩组合。火山岩碱度主要为钙碱性。火山岩形成环境为活动大陆边缘区,这与本区所处大地构造位置相吻合。根据当前火山岩的研究现状,尝试性地对该盆地髫髻山组火山岩进行了火山喷发旋回层序的划分,共划分了四级火山喷发旋回层序。其中 A-A′剖面Ⅰ级 1个,Ⅱ级 5个,Ⅲ级 17个,Ⅳ级 21个; B-B′剖面Ⅰ级 1个,Ⅱ级 5个,Ⅲ级 18个,Ⅳ级 24个。
