文章摘要
Ordos Basin, China’ questioned the viewpoint that high-gamma-ray sandstone might be caused by
homochronous sedimentary volcano tuff ash or previous tuff. The authors argued that the main reason
for the high-gamma-ray sandstone should be from high Th and U contents in zircon. In reply, we discuss
the problems with the authors from the category of high-gamma-ray sandstones, rock characteristics, and
possible sources of radioactivity. The results still indicate that the high gamma ray characteristics might
be caused by homochronous sedimentary volcano tuff ash or reworked previous tuffs.
