2. CORRELATION OF THE DEP£RET AND MATET TIME DIVISIONS WITH 



HUMAN INDUSTRIES 



Correlation: Chellean Industry = Second Interglacial Period= Terraces 



of 28-32 Meters 



This correlation by Mayet (1921.1, 1921.2) agrees with Penck's corre- 

 lation of 1909 (Penck and Briickner, 1909.1), with the observations on 

 the Somme Valley by Commont (1906-1914). and approximately with 

 Obermaier, 1922 (see footnote on page 445). Mayet states (1921.1, 

 page 6) : 



"De ce qui precede, on pent conclure que la migration humaine — d'origine 

 encore inconnue — ayant amene nos premiers ancetres sur notre sol. s'est faite 

 an cours du Tyrrhenien. lors de Verification de la terrasse de 80 metres, done 

 apres le maximum d'extension glaciaire en Europe, apres la glaciation Minde- 

 lienne. lis sont venus, apportant l'industrie ohelleenne, e'est-a-dire uue tech- 

 nique deja perfectiounee de la taille du silex impliquant une longue phase 

 anterieure de differenciation psychique, de culture intellectuelle.'"

There is indicated thereon the paleolithic station where Chellean flint implements were 

 first discovered. The uneven line hetween the Chellean and Acheulean heds represents 

 an intervening interval of erosion. The Acheulean-Mousterian succession is regular and 

 unhroken. According to recent correlation : 



Mousterian industry, beginning in Third Interglacial Time. 



Acheulean industry, beginning in III Glacial Time (Riss). 



Chellean (and pre-Chellean) industry, beginning in Second Interglacial Time.
