Location and accuracy | Location plotted is locality 42 (sample 50ATr61) from original 1950 field notes and maps of Tailleur and cited by Patton and Matzko (1959, p. 12), in T9S,R21W; at east end of westernmost Lisburne ridge, just west of Blankenship Creek; within 1000 ft (305 m). |
Geologic descriptionSample from an 8 ft. zone of rubble of black chert, black paper shale, black shaly dolomite, and oolitic phosphate rocks in the Carboniferous Lisburne Group; there probably are 2 horizons (each about 6 in. thick) of phosphate rock (Patton and Matzko, 1959, p. 11-12). Stratigraphic position in Lisburne Group uncertain. | |
