  • Golden Pocket Guide Rocks, Gems, and Minerals

    Includes information on collecting and identifying minerals, and sections on metallic, nonmetallic, gem and rock-forming minerals, and on igneous, sedimentary and metamorphic rocks.

    This is a great little pocket guide to rocks and minerals. It uses color drawings to illustrate the rocks and minerals which I find is far more handy that pictures of museum quality specimens. Rocks and minerals in the field often don't know what they're supposed to look like so they are more average than those museum exhibits!

  • Deluxe Moh's Mineral Hardness Pick Set

    The Deluxe Moh's Hardness Pick Set now comes in two case types. The wooden case is small enough to carry and the top screws into the base to make a perfect desk stand. The plastic case is longer but the thinner size makes it easier to carry in your field tool set.

    Hardness is an important and quantifiable physical characteristic of a mineral and in your effort to identify an unknown mineral, the hardness, if known, combined with other properties, can narrow your search to just a handful of possibilities. Simply scratch a smooth surface of your unknown mineral with the picks of various indicated hardness. As an example, if a No. 5 pick scratches the mineral, but a No. 4 pick does not, then your mineral hardness is 4.5. Then compare this against a table of minerals listing hardness values to aid in identifying the unknown mineral.
    The Deluxe Mohs' Hardness Pick Set from Mineralab is unique in that, unlike other mineral hardness test tool that use minerals or crystal points, Mineralab picks are made of metals and alloys of hardness values equal to 2 through 9 on Mohs hardness scale. Because the picks are made of metal, they are easily ground to sharp points which will not break off and which can be easily sharpened.

    What is included in the Mineralab's Deluxe Mohs' Hardness Pick Set?

    • Four double-ended picks with eight points comprising 2 and 3, 4 and 5,
      6 and 7, 8 and 9 on Mohs’ hardness scale.

    • High quality brass pinch vises.

    • A glass plate (hardness of about 5.5) which, when scratched,
      quickly distinguishes hard from soft minerals.

    • A second hardness plate with a hardness value of 3.5.

    • A streak plate for testing a mineral’s streak color.

    • A magnet to test magnetic rocks such as magnetite and pyrrhotite.

    • A 100 grit polishing stone to keep the points sharp.

    • An attractive, mahogany-finished and compact wooden case.

    • Complete usage instructions.


    Other Features:

    • All points are stamped with the indicated hardness value, and each double-ended
      pick body is color coded for quickly finding the desired pick.

    • Hardness points can be easily and inexpensively replaced without having to
      replace the pick bodies.

    • Compact. The wooden storage case is only 7" tall by 2.5" wide.

    • Also use to test hardness of various materials encountered in the industrial,
      excavation, and archeological fields.

    • 1 Year Warranty

  • Estwing Leather Sheath for Pointed Tip Rock Hammers #3

    Estwing Leather Sheath for Pointed Tip Rock Hammers

    New model. The sheath now has a "relaxed fit" making it easier to use in the field as well as working with more hammers.

    Fits Estwing Pointed Tip Rock Hammers. Now fits the Estwing Supreme 24oz Big Face Pointed Tip Rock Hammer and the Valley Soft-Touch 20oz Pointed Tip Rock Hammer.

    Leather snap case for the Estwing 24 oz, 22 oz, 13 oz, and 14 oz Rock Picks. Difficult to use until well broken in. We recommend the Gfeller Casemakers sheaths and holsters, especially the holsters. The Gfeller sheaths are sized better and their also pre-shaped to fit the hammers.

     

    (I placed this on the site when the sheathshad a tight fit. It's still handy information." Hint: to make it easier to use this sheath use products like Vaseline, mink oil, saddle soap and even soap to help break it in. If you've recently broken in a baseball glove you may have some Rawlings Glovolium and Easton Glove oil around. Don't over do it. Do a web search on breaking in a baseball glove to find out how they do it.

     

    I still don't recommend using the Estwing Leather Sheaths in any case. I sell them because some customers insist on having a sheath to protect things from the hammers. They're OK for storage but Amateur Geologist never carries one into the field. Use a holster.

    Did I mention that these sheaths are just too difficult to use.

    In a lively and engaging style, Sloan describes forces such as the movement of tectonic plates, erosion, the waves on the coast, and human activity. She provides background information on the processes, time frame, and rocks that are the key to understanding the Bay Area landscape and geologic history, then turns to distinct regions of the Bay Area and to San Francisco Bay itself.
