  abstract = {{A} magnetostratigraphy is established for the {M}elka {K}unture archaeological site of {E}thiopia, whose chronological setting needed improvement. {T}he magnetostratigraphy is constructed from four distinct stratigraphic sections, {G}arba-{IV} (5 sites), {G}ombore-{I} (21 sites), {G}ombore-{II} (8 sites), and {S}imbiro (13 sites). {N}atural remanent magnetizations ({NRM}) were measured and analyzed over a total of 214 specimens to isolate the characteristic components of magnetization and determine magnetic polarities. {T}wo magnetization components were isolated in every sample analyzed: (i) a low-temperature (low coercivity) secondary normal component and (ii) a high-temperature characteristic component of normal or reversed polarity and allows to identify five magnetozones ({N}1-{R}1-{N}2-{R}2-{N}3). {R}ock magnetic analysis attests that the magnetization is carried by magnetite or titanomagnetite within the range of pseudo-single domain grain sizes. {A}nisotropy of magnetic susceptibility ({AMS}) supports a sedimentary origin of the magnetic remanence. {B}ased on recent {A}r-40/{A}r-39 geochronological dating of the site, faunal constraints and a magnetostratigraphic pattern, the sequence is correlated to the time between the early {M}atuyama chron (< 1.80 {M}a) and early {B}runhes chron (similar to 0.709 {M}a) of the geomagnetic polarity time scale ({GPTS}). {C}ompleting recent {A}r-40/{A}r-39 age series, the magnetostratigraphy study presented here allows computation of interpolated ages for various faunal and artifact findings at {M}elka {K}unture and similar fossiliferous deposits in the region.},
