鄂尔多斯盆地晚古生代陆源碎屑沉积源区分析
STUDY OF THE DISPOSITIONAL PROVENANCE OF THE TERRIGENOUS DETRI TUS IN ORDOS BASIN IN LATE PALEOZOIC ERA
摘要
Abstract
In this paper, by researching the sandstone type, the distri bution and change of lithic fragment types and the distribution and change of t he heavy minerals assemblage type in the Ordos Basin during the Late Paleozoic era, the authors divide the basin into several districts. These di stricts have the traits of semblance and inherence, and at the same time, they basically are c onsistent with the sandstone body distribution and the paleo-current direct ion. Ac cording to the foregoing fact, the authors can reach the conclusion at least as follows: There are five delta sedimentary systems form early Dias to middle Dias. They are Shenmu-Suide delta system, Wushengqi-Jingbian delta system, Y in chuan-Wuhai delta system, Pingliang-Huanxian delta system and Tongchuan-Hanch eng delta system, respectively. Their places of origin, in turn, are Yingshan paleo -land in the north, Alashan paleo-land in the north-west, Liupanshan paleo-land in the south-wes t, a nd Qilian-Qingling paleo-land in the south. Therefore that the terrigenous detrital materials have several places of origin is the major feature of the Paleo zoic disposition of the Ordos Basin.关键词
