Mar 23, 2018 (Therese Pettigrew) - The iron formation consists of beds of white laminated chert, red chert, magnetite (some of which is hematitic), and siderite, with scattered tuff beds. The north (top) part of the iron formation is brecciated, the south part undisturbed. Microscopic examination of the laminated chert reveals small euhedral crystals of magnetite in groundmass of finely crystalline chert (AFRI 52A05NE8102).
