Argon retentivity of hornblende appears to be little affected by a large Eocene diorite batholith, except near the contact. Whole-rock phyllitesamples from the same terrain give mid-Tertiary age values, suggesting considerable argon loss. This content is PDF only. Please click on the PDF icon to access.
