Abstract

This paper gives account of the results obtained on the macromorphological, analytical and rninerailogical study of three representative HAPLOXEROLLS from the province of Murcia (Spain). They show an A-B-C profile, with an A horizon reaching 40-50 cm in depth, and enough organic matter content to be a moUic epipedon. Taking into account the variations of the organic mater and equivalen calcium carbonate contents with depth, the fluventic characteristics of the profile are evidents. Calcareous from the surface, these soiis are saturated, being calcium the dominant exchangeáble catión. The heavy mineral fraction from the fine sand is made up by resistant minerals with tourmaline as the main component, making up several associations with other minerals. The clay fraction shows a rather complex mineralogical composition, with illite and caolinite as the main components and vermiculite, chlorite, smectites, quartz and athapulgite in minor amounts.
