Geochemical and mineralogical comparison of a sequence of "wet" and "dry" samples from theIIzarra-1 drilling belonging to the Zufía formation (Estella, Navarra) has been made. The following techniques have been applied; X-rays, over total dust and gas crhomatography, over fraction obtained after a disolvent extraction of the organic matter. These techniques show a high relation between the two types of samples, changes either in mineralogical composition nor in organic composition not being seen. Futhermore, the anoxic character; the maturity degree and the continental origin of the organic matter is observed.
