This study on the distribution features of petroleum hydrocarbon in water and sedi-ment off the Fujian shore using data obtained from the baseline research on oceanic contamination in Fujian showed that:during the research preiod,petroleum hydrocarbon concentrations in water varied from 5.77μg/L to 37.28μg/L,averaged 14.48 μg/L;was lower in the wet seasson than in the dry season;and was highest in the Minjiang Estuary and Jiulong Estuary in both seasons ,The petorleum hydrocarbon concentrations in shore sediment varied from 14.48 mg/kg to 784.36 mg/kg,averaged 133.3 mg/kg ,and was closely related to sediment types (granularity).  相似文献

Geology of the Dolomites     

AlfonsoBosellini PieroGianolla MarcoStefani 《《幕》》2003,26(3):181-185

The Dolomites region is a spectacularly exposed portion of the Southern Alps, a northern Italian chain derived from the comparatively gentle deformation of the Tethyan passive continental margin of Adria. The regionhad an active Permo-Jurassic tectono-magmatic evolu-tion, leading from Permian magmatism, through a Mid-die Triassic episode offast subsidence and volcanism, to the Jurassic oceanic break-up. Although the sedimentary succession ranges in age from Middle Permian to Creta-ceous, the geological landscape is largely dominated by the majestic Triassic carbonates, making the area a clas-sical one for the early Mesozoic stratigraphy. Particu-larly noteworthy are the Anisian to Carnian carbonate platforms, recording an evolution from regional muddy banks to isolated high-relief builduos. The hlline of the various basins and the development of a last generation of regional peritidal platform followed. The carbonate platforms of the Dolomites bear witness to a remarkable set of changes in the carbonate production and to signif-icant palaeoclimatic fluctuations,from arid to moist con-difions and vice versa; a great range of margin and slope depositional styles is therefore recorded. Alpine tectonic shortening strongly affected the area, with a first Eocenede formation, followed by later Neogene overthrusting and strike-slip movements.  相似文献

靖安油田北东区局部构造与石油富集关系研究   总被引：8，自引：0，他引：8  

王平周义  季海锟 《长安大学学报(地球科学版)》2003,25(4):9-12

鄂尔多斯盆地的形成演化进入第四阶段时，靖安油田北东部发育了延长组和延安组沉积，它们是主力产油层。区内石油产层的局部构造主要分为岩性差异压实作用所形成的局部性隆起；古地形突起上覆地层形成的披覆构造；由差异升降作用造成，但相对较少且不易与前两类区分。区内的局部构造与石油开发关系密切，直接影响油井产量。  相似文献

我国已为世界石油消费增长最快，仅次于美、日的第三大石油消费国，而且，我国石油接替资源和后备可采储量日趋紧张。今后10～15年，如果没有重大发现或技术上的突破，我国原油将面临严重供不应求的窘境。到2015年，将有一半原油需要进口。令人担忧的是，我国至今还没有一个完整的石油战略储备体系。随着石油进口量的迅猛增加，建立国家石油战略储备体系刻不容缓。  相似文献
