Inclusions of dark rock believed to be recrystallized volcanic material in diorite. Hugh Miller Inlet. Glacier Bay National Park and Preserve, Alaska. Glacier Bay National Park and Preserve, Alaska. Hugh Miller Inlet. Inclusions of dark rock believed to be recrystallized volcanic material in diorite. Relations of inclusions to diorite show that both active intrusion and replacement of dark rock by diorite have taken place. The dark inclusions probably represent later additions to the melt and, hence, are not so thoroughly "digested." Circa 1950. Figure 12 (upper photo), U.S. Geological Survey Bulletin 1121-K.
