The deposits themselves contain chalcocite, malachite, and azurite and occur at several horizons in Pennsylvanian and Permian rocks, ranging from coarse conglomerate through sandstone to shale. Woody fragments are common in the beds, and seams of lignitic material are present locally. The prevailing color of the formation is a deep brownish red, which is due to the presence of abundant ferric oxide, but the beds that contain the copper are bleached to gray or greenish gray. A few hundred to a thousand feet west of the north-south Red Gulch fault the beds begin to dip more steeply eastward, and at the fault they have at many places assumed a vertical position. Only a few minor transverse east-west faults are present. The only rock intrusive into the redbeds is a thoroughly oxidized east- west dike, a quarter of a mile north of Springfield; it is said to contain a little silver, but it has no apparent connection with the copper deposits.
