    Description

    VINTAGE!! RARE!!
    This is USGS Bulletin 920,
    Pre-Cambrian Geology and Mineral Resources of the Delaware Water Gap and Easton Quadrangles, New Jersey and Pennsylvania.
    Published in 1941, this is a scarce old report. It consists of the 98-page book and THE ORIGINAL LARGE FULL-COLOR GEOLOGIC MAP, plus a foldout map bound into the text. This is a very interesting area with numerous old mines. Prospects and mines discussed in this book include:
    Ahles mine
    Washington mine
    Durham mine
    Barton, Kaiser, West End, and Swayze mines
    Titaniferous magnetite mines
    Marble Mountain mine
    Titman prospect
    Williams Shaft
    Shoemaker mine
    Orchard mine
    Raub mine
    Weldon mine (with fold-out level map)!
    And Others!
    Some of the mines were two hundred years old when this was written, so this is an important historical document as well as a good reference on the area’s mineralogy and mines. Minerals found in some of the area’s mines include:
    Augite
    Biotite
    Calcite
    Chlorite
    Epidote
    Feldspar
    Fluorite
    Ferrohornblende
    Garnet
    Hematite
    Limonite
    Magnetite
    Microcline
    Oligoclase
    Pyrolusite
    Rutile
    Sericite
    Tourmaline
    Sphalerite
    And others!
    This is a great book on an area rich in history and geology. The color map is really beautiful, and is done in an older style that looks really cool. It would look great framed and hung in a home or business in the area.
    BONUS
    : I am including this report as well, which overlaps the same area:
    USGS Bulletin 1244-H,
    The Martinsburg Formation (Middle and Upper Ordovician) in the Delaware Valley, Pennsylvania-New Jersey
    . This 16-page booklet was issued without covers in 1967. It discusses the Martinsburg formation, and how mapping in the area of eastern Pennsylvania and western New Jersey showed it could be divided into three sub-units or members. Some interesting photos are provided in the text. The sub-units are described. A nice addition to the geology of the region and a good accompaniment to the other report.
    Expert packing assured. Shipping weight is seven oun
    ces. Media Mail is provided to save you a bit.
