76 THE U. S. GEOLOGICAL SURVEY 



geology, paleontology, and metalliferous, non-metalliferous, 

 coal, oil, and gas deposits. Each section maintains its own 

 field parties, which, while giving attention in their examina- 

 tion primarily to the special province of the section, also gather 

 data relative to the general geology of the areas examined. 

 Thus, while the sections on areal geology are primarily re- 

 sponsible for the determination and mapping of the areal 

 geology of the regions they examine, they receive assistance 

 from other sections in their work in areas with which those 

 sections come into special contact. The sections of the divi- 

 sion are as follows : 



i. Administrative and General 



2. Section of Eastern Areal Geology 



3. Section of Western Areal Geology 



4. Section of Coastal Plain Investigations 



5. Section of Glacial Geology 



6. Section of Paleontology and Stratigraphy 



7. Section of Geology of Metalliferous Deposits 



8. Section of Geology of Non-Metalliferous Deposits 



9. Section of the Geology of Eastern Coal Fields 



10. Section of the Geology of Western Coal Fields 



11. Section of the Geology of Oil and Gas Fields 



The two sections of Areal Geology perform reconnaissance 

 and detailed work in areal or general geology, in pursuance of 

 the plan to complete the geologic atlas of the United States. 

 The Sections of Eastern and Western Areal Geology make 

 investigations east and west of the one hundredth meridian, 

 respectively. 



The Section of Coastal Plain Investigations carries on a 

 study of the geology of the Atlantic and Gulf coastal plains 

 of the United States, with special reference to their geologic 

 history, giving particular attention to investigations of the 

 stratigraphy, paleontology, and origin of the various forma- 

 tions.
