Analysis of Drill Core from the Siljan Ring Impact Structure and Related Processes in Shear-Zone Terranes. Final Report October 1, 1986-September 30, 1989

摘要

Sampling has been conducted at the Siljan Ring, Sweden on the surface from inside and outside of the ring, from drill core in pilot holes, and from drill core and cuttings in the deep Gravberg hole. Petrographic, fluid inclusion, stable isotopic, and electron microprobe analyses were made. Four journal articles and six abstracts have been published describing this work. These studies have not detected volatiles other than H2O in fluid inclusions from quartz in the granite.
