    Description

    FEW LEFT!!!
    This is USGS Bulletin 1141-P,
    Geology of the Cleveland Quadrangle, Bearpaw Mountains, Blaine County, Montana
    . Published in 1964, this is a pretty scarce item. This publication documents the geology of this interesting area. It consists of the 26-page book and a HUGE FULL COLOR GEOLOGIC MAP covering about 200 square miles of mountainous country and some of the adjacent plains. This area has quite complex geology of faulted sedimentary rocks plus intrusive and volcanic igneous rocks. The igneous rocks are an odd mixture of alkalic rocks with weird names like shonkinite, syenite, phonolite, and latite. They are part of a large group of similar rocks, all introduced during the Eocene.
    Some prospects in the area were investigated for various metals. The text mentions some of the minerals found, including
    Galena
    Pyrite
    Chalcopyrite
    The report covers the geology in great depth. Every formation is described completely, and the map has several nice cross sections on it that make the geology really come alive.

    Expert packing assured. The recent increase in postage rates was pretty big. As a result, Media Mail is now my default shipping method to keep shipping affordable.
