  abstract = {{T}he objective of this work was to assess the relationship between macrofauna, mineralogy and exchangeable calcium and magnesium in {C}errado {O}xisols under pasture. {T}welve collection points were chosen in the {D}istrito {F}ederal and in {F}ormosa municipality, {G}oias state, {B}razil, representing four soil groups with varied levels of calcium + magnesium and kaolinite/(kaolinite + gibbsite) ratios. {S}oil macrofauna was collected in triplicate at each collection point, and identified at the level of taxonomic groups. {M}acrofauna density showed correlation with contents of kaolinite, gibbsite and exchangeable {C}a + {M}g in the soils. {M}ineralogy and exchangeable {C}a + {M}g had significant effects on taxonomic groups and relative density of soil macrofauna. {T}he termites ({I}soptera) were more abundant in soils with low exchangeable {C}a + {M}g; earthworms ({O}ligochaeta), in soils with high levels of kaolinite; and {H}emiptera and {C}oleoptera larvae were more abundant in gibbsitic soils with higher contents of total carbon.},
