Cross Section Of The Upper Elkhorn Coal Zone Between The Mcdowell And Jenkins West Quadrangles, Bradford L. Luckett
Cross Section Of The Upper Elkhorn Coal Zone Between The Mcdowell And Jenkins West Quadrangles, Bradford L. Luckett
Map and Chart--KGS
This cross section shows lithic variation and coal-bed correlations for the interval between the Upper Elkhorn No. 1 and the Upper Elkhorn No. 3 ½ coals in eastern Letcher and southern Floyd Counties. It is one of a series being made to document the characteristics of the Upper Elkhorn coal zone in eastern Kentucky. The data are derived from the KGS coal borehole database, which contains records of exploration core holes supplied by coal companies. Lines on the diagram show general bed correlations and indicate places where mineable coal beds split into two or more thinner benches. The vertical alignment …

Cross Section Of The Upper Elkhorn Coal Zone Between The Evarts And Benham Quadrangles, Bradford L. Luckett
Map and Chart--KGS
This cross section shows lithic variation and coal-bed correlations for the interval between the Upper Elkhorn No. 1 (Harlan) and the Upper Elkhorn No. 3 ½ coals in Harlan County, Ky. It is one of a series being made to document the characteristics of the Upper Elkhorn coal zone in eastern Kentucky. The data are derived from the KGS coal borehole database, which contains records of exploration core holes supplied by coal companies. Lines on the diagram show general bed correlations and indicate places where mineable coal beds split into two or more thinner benches. The vertical alignment of logs …

Cross Section Of The Upper Elkhorn Coal Zone Between The Varney And Lick Creek Quadrangles, Bradford L. Luckett
Map and Chart--KGS
This cross section shows lithic variation and coal-bed correlations for the interval between the Upper Elkhorn No. 1 and the Upper Elkhorn No. 3 ½ coals from southern Martin County to central Pike County. It is one of a series being made to document the characteristics of the Upper Elkhorn coal zone in eastern Kentucky. The data are derived from the KGS coal borehole database, which contains records of exploration core holes supplied by coal companies. Lines on the diagram show general bed correlations and indicate places where mineable coal beds split into two or more thinner benches. The vertical …
