A field technique for identifying and dating radiolaria applied to British Columbia and Yukon
Résumé
With a mobile laboratory, the radiolarian specialist is able to process samples and identify radiolarian
fauna in the field. In summer 1989 a few age dates were obtained in base camps in the Bridge River
and Cache Creek complexes in southern and northwestern British Columbia. This technique can be
applied concurrently with field mapping programs to provide a quick understanding of the stratigraphy
and structure of geological units, and eventually influence mapping schedules. This approach is particularly
useful in complexes with large amounts of siliceous, argillaceous and/or tuffaceous sedimentary strata
