Description :
A study of the variation in cement amounts in aeolianite and sandy beach calcarenites that range in age from Holocene to Last Interglacial is used to assess whether a palaeoclimatic control on vadose diagenesis can be identified. Examples are taken from modern-day arid to subhumid settings and represent a geographical distibution ranging from Libya and Oman, to the Mediterranean, the Caribbean and Mexico. The results indicate that a palaeoclimatic signal can be identified in some deposits. However caution is needed when studying the role of climate in vadose diagenesis in the light of the effects of other intrinsic and extrinsic controls.
