【摘要】 对于柴达木盆地柴东三湖地区第四系驼峰山构造带是否存在物源及物源的发育时期,一直存在争议。本文通过对驼峰山典型单井的层序和沉积相综合分析、常规地震剖面及瞬时相位剖面、地球化学资料和重矿物资料的综合对比分析后,认为驼峰山构造带在第四系更新世早期的层序一(SQ1)时期是存在物源的,且属于远源物源,物源规模较小,分布范围局限,时间上继承性不强,仅在层序一时期发育;驼峰山构造带的物源与同属北坡的盐湖和哑叭尔地区的物源母岩区不同,分属不同的沉积体系。更多还原

【Abstract】 The debate on sedimentary source in Tuo Fengshan tectonic zone and the developed time have been presented.The standpoint of this article is that sedimentary source have been exited in the SQ1on Eopleistocene in Quaternary,by researching sequence stratigraphy and depositional facies of individual wells,rule seismic cross section,instantaneous phase profile,geochemistry and heavy mineral datum,which is far away form the denuded area,smaller scale,non-successional in geohistory.The source of Tuo Fengshan tectonic zone is not a part of the northeastern depositional system.更多还原
