摘要
根据巫山望天坪剖面31个样品系统的元素地球化学测试结果,分析讨论了了巫山第四纪沉积物的常量元素、微量元素以及稀土元素(REE)的地球化学特征及其分布规律,并与我国典型风成沉积物作了相关对比研究.结果表明巫山第四纪沉积物的化学成分与我国典型风成沉积物既有较好的相似性.元素地球化学分析初步表明,巫山第四纪沉积物是风成大气粉尘堆积物.
According to Section 31 Wushan Wangtianping element geochemical samples of the system test results, analyzed and discussed in Wushan quaternary sediments, trace elements and rare earth elements （REE） Geochemistry and distribution law, and with our typical Aeolian sediments were related to comparative study. The results showed that the chemical composition of Wushan quaternary sediments and into the sediments of the typical Aeolian has good similarity. Element geochemical analysis of the show,Wushan quaternary sediments deposits are deposits of atmospheric dust.
