A previous study of Plio-Pleistocene lavas from the equatorial Galapagos Islands(latitude～1°S)that used an adjustment for multidomain(MD)effects[Wang and Kent,2013G-cubed]obtained a mean paleointensity of21.6±11.0μT(all1σ)from27lava flows[Wang et al.,2015PNAS].This is about half of the present-day value.Here,in a pilotstudy to check this result,we utilized previously thermally demagnetized specimens ofPlio-Pleistocene lavas from the Mt.Kenya region and 31 lava sitesfrom Loiyangalani region with coherent directions and not exhibiting any indications ofhaving been struck by severe lightning. Rock magnetic data show that the mainmagnetization carriers are fine-grained pseudo-single-domain magnetite with saturationremanence to saturation magnetization ratios (Mr/Ms) ranging from ~0.05 to ~0.60 [Opdykeet al., 2010, G-cubed].
