Sommario/riassunto |
|
This report presents biostratigraphic data from 289 collections at 189 localities in the De Long Mountains, Misheguk Mountain, and Noatak quadrangles; most of these data have never been previously published. The collections were made during studies of the Red Dog massive sulfide deposit in 1998-2004 and in support of regional mapping projects in 1979, 1981, 1983, and 1997-98. The collections--mostly conodonts and some radiolarians--tightly constrain the age of many stratigraphic units of Devonian through Triassic age exposed within the study area, and provide additional data on the depositional environments and thermal history of these rocks. |
