Silt-sized sediments and gypsum on surface formations in the Ebro Basin: a disambiguation of the term “gypsiferous silts”

Geologica Acta, 2021
The term “gypsiferous silts” has been used since the 1960s by many authors, but it has relied on unclear, am-biguous criteria that attributed aeolian, colluvial or alluvial origins to these materials.
