The manganese oxide minerals, a preliminary report
Michael Fleischer, W.E. Richmond
1943, Economic Geology (38) 269-286
This paper summarizes the results obtained thus far in an intensive study of the manganese oxide minerals. X-ray powder photographs, supplemented by chemical tests, have proved to be the best means for identifying these minerals. Formulas are suggested. Physical properties and X-ray data are listed for the commoner minerals and...
Structural determinations from diamond drilling
John Beaver Mertie
1943, Economic Geology (38) 298-312
Several problems may arise in the geometrical determinations of strike and dip from core drilling.

Some time previous to...
