Figure 138. Average Miocene and Eocene shale densities in Zamuro No. 1, Falcon, 

 Venezuela. Note density increase at unconformity indicating that Eocene may 

 have been buried much deeper than at present, and that considerable section 

 was removed before deposition of Miocene. (Data by C. C. Fritts, Jr.)
