Some water-lain sediments samples with different ages were selected from several regions in China,and their Standardized Growth Curves(SGC)were constructed for fine-grained quartz OSL signals that were measured by sensitivity-corrected multiple aliquot regenerative-dose protocol(SMAR).

When the preheat time is fixed as 10s,the De preheat plateau regions are 250～280℃ and 180～260℃ for regeneration dose and test dose respectively for fine-grained quartz in Chinese loess,no matter using single-aliquot regenerative-dose(SAR)protocol or sensitivity change corrected multiple-aliquot regenerative-dose(SMAR)protocol.

Surface characteristics and environment implication of quartz grains in Cretaceous desert of North Jiangsu Basin;

,After a study of macroscopic features for the Quaternary glacial vestiges in the Tanzhesi area of the Western Hills of Beijing,the analysis of the appearances and assemblage features of quartz grain surface textures has been carried out for the palaeoglacial deposits of the Guantuoling and Zhaojiatai glaciations.

This paper addresses on the surface characteristics of the quartz particles in the profile of quaternary red earth,Xuancheng,Anhui province.
