Abstract

The determination of depositional environments is an effective means for basin a nalysis, palaeogeography and palaeoclimate study and oil reservoir judgement. Qu artz has relative high hardness and chemical stability, therefore its sedimentar y grain surface features can well reflect the depositional environments. And usi ng electronic scan microscope to study quartz grain surface microscopic features is also an effective method to analyze depositional environments. Although it h as been widely accepted that there occurred desert sediments in the early Cretac eous Zhidan Group in the Ordos Basin, the systematic analysis of quartz sand grain surface microscopic features is lack. This paper shows the result of the quartz sand grain surface microscopic feature analysis from the Louhe Formation and Luohandong Formation of the early Cretaceous Zhidan Group in the Ordos Basin. It reaches that the microscopic features are of distinct eolian characteristic s and the analysis can easily distinguish eolian from hydrogenic sediments. Ther efore, our study confirms the existence of the Cretaceous desert in the Ordos Ba sin with the respect of quartz sand surface microscopic features.
