Summary[edit]
| Description |
English: Myrmekite with coarse quartz vermicules (white and cream), enclosed in microcline (grid pattern, light gray). Plagioclase of myrmekite is speckled brown (sericite alteration). Microcline penetrates the plagioclase along fractures and encloses some of the coarse quartz vermicules. Similar-sized or smaller islands of quartz occur in the microcline (top) as ghost myrmekite. Wanup Pluton near Sudbury, Ontario, Canada. Courtesy Dr. L. G. Collins. |
