308 THE IRON ORE DISTRICT OF EAST TEXAS. 



11. Gray sand, fine in texture, with much pyrites. 5 feet. 



1 2. Black clayey sand. . 12 feet. 



13. Gray sandy clay, with broken fragments of lignite sometimes making up one- 



half the mass 10 feet. 



Total 83 feet. 



These two sections, in connection with the various similar sections of the 

 adjoining counties, give an idea of the rock materials of the region. The 

 Elkhart section represents a part of the upper portion of the Oil Wells sec- 

 tion, No. 8 of the Elkhart section being possibly the No. 3 of the Oil Wells 

 section. 



The amount of dip is very small. In places it appears to be as much as 

 three to five degrees, but this is only local and usually due to sub-erosion. 

 No accurate determination can be made until more detailed work is carried 

 on, lines of levels run, and the various separated beds mapped and correlated. 



QUATERNARY. 



The extent of the Quaternary modifications of the underlying materials 

 and the deposits directly referable to that period have not yet received suffi- 

 cient study to enable us to do more than indicate their existence and desig- 

 nate some of the members. A part of the iron ores are possibly of this 

 period, while the overlying quartzitic and quartzose sandstone and gray, yel- 

 low, or buff colored sands, together with some of the mottled sands or sandy 

 clays and gravel, certainly belong to it. 



THE IRON ORES. 



The deposits of iron ore in Anderson County, like those of the entire dis- 

 trict, are found capping the highest hills, or, in the case of some of the con- 

 glomerate ores, along the water courses, either at their present level or more 

 often at that of some time prior to the erosion of its present channel. As 

 lias already been stated, these deposits are found cresting a rude semicircle 

 of hills having for its diameter the Neches River, and are in fact the western 

 extension of the deposits of Cherokee County. 



••Going north from Palestine the main iron bearing range is met at about 

 three miles from the town, and extends in a great plateau, often broken up 

 into separate flat-topped hills, from here northerly towards Beaver, Brushy 

 Creek, Kickapoo, and the Henderson County line. 



"The ore found here is continuous over large areas and maintains a very 

 steady thickness of from one to three feet. To the south of Palestine the 

 same ore is found, but here the bed is generally thinner and less continuous, 

 and the ore bearing hills more scattered." Therefore, the iron range in the 

 great highland region to the north of Palestine comprises most of the ore of
