  abstract = {{T}he tepetates of {M}exico {H}ighlands are indurated horizons with fragipan pr0perties. {T}epetates appear among pyroclastic deposits ({T}1, {T}2, {T}3). {A} soil profile located near {T}excoco, {M}exico, including tepetate layers was studied. {M}ineralogical and microscopical features of this profile were studied using a series of methods. {T}his report the main results of the study. {T}epetates were characterized by several features: first, the nature of their parent material; second, a close matrix microstructure and third, their colloidal fraction. {T}he latter is conformed mainly by laminated 1:1 to 2:1 mixed layer minerals made of flaky layers. {T}hese features can explain the fragipan properties of tepetates and most of their mechanical behaviour.
