Summary:A study of four terrae rossae over limestone in S Spain is reported, including an investigation of the autochthonous or allochthonous nature of the soil material in relation to the rocky substrate. Some of the quartz grains represent insoluble residue and some are probably wind blown from desert and coastal cources; micas in the fine earth fractions are inherited from the insoluble residue. This mica has less [4]Si and [6](Fe,Mg) and more [4]Al, [6]Al and x (layer charge) than the soil clay; it also has more 2M1 and less 1M polytypes. The kaolinite has varied origins including neoformation and inheritance from underlying rock. [R.A.H.]
