The magnetic features of the three eolian loess profiles located respectively in Lanzhou

Linxia and Xinin basin

the three sub-basins of Longxi basin are the same. All are charaterized by developed Lination and their susceptibility shape-ellipsoids are of extended-shape and foe maxium average susceptibility direction (Kmax) are from NW to SE

which are mainly related to its source material coming from the northernwest areas.
