It is massivelybedded, and in some localities contains some very thick bedsof pure wiiitish lime rock. This great limestone formation forms a remarkable corniceon the Sandia mountains, clearly seen from the railroad sta-tion at Albuquerque. It is also an important part of the Man-zano, Magdalena, Socorro, Caballos, Lad rones, San Andreasand Sacramento ranges. In most of the districts the carboniferous limestone carriesimportant lead and silver deposits. The quartzite also carriescopper. Above the blue limestones of the carboniferous comes in animportant sandstone, and then a sequence of shales and sand-stones conspicuous for their remarkable red coloration. Redbeds they are generally called. These Permo-carboniferous red beds are found ever3^whereat the foot of the back slope of the central New Mexico moun-

In the Sandia mountains the lower sandstone is called theCoyote sandstone from Coyote Springs, and the upper mem-ber of the Bernalillo shales. These red sandstones and shales are notable for the copperores everywhere distributed through them. There appears to be small doubt that the upper part of thegreat formation, long called the red beds, belongs to a latergeological age than the carboniferous.

In New Mexico these beds are largely developed in thenortheastern part in the Cimarron, Canadian and Pecos Val-leys, and in the central part in the Rio Grande Valley, Inthickness the measurement is probably greatly in excess of500 feet. The important ore deposits are chiefly those of copper andiron. Gypsum, fire clays and cement materials abound. The cretaceous formations
