The relationship of regional geology to the types of placer deposits (with emphasis on epithermal deposits forming eluvial placers and how to metal detect them.)

Meteorites - Mining Districts - Gossans - Laterities

Jim Straight has been involved in some form of prospecting for over half a century.

Jim found his first detected nugget on a hardrock mine dump near Tonopah, Nevada. For the last fifteen years he has metal detected both desert dryplacer areas and hardrock gold mines.
He is a 1954 graduate of the Mackay School of Mines, University of Nevada. Jim has a B.S. degree in Geological Engineering and has completed post graduate classes in Mining.

"ADVANCED Prospecting & Detecting for Hardrock Gold" has been written especially for the serious student who is self-committed and willing to study and become more knowledgeable. This booklet is not a simple course in "Introduction to Nuggetshooting 101." Instead, it is meant to be "Advanced Nuggetshooting 421" and is intended to be semi-technical. It will lead the serious detectorist, who is determined to find gold nuggets, along a learning path by introducing little-known technical aspects and correct terminology.

Explanations, references, illustrations, charts, tables, and a glossary round out the basic information. Emphasis is placed on epithermal deposits that have formed eluvial placers, "how to" detect them for gold nuggets, and "how to" understand the relationship of regional geology to the types of placer deposits.

  • Field Geology Illustrated, 2nd Edition

    This is one of our highly recommended books. Field Geology Illustrated, 2nd Edition is a reliable, in depth field reference for professional geologists, serious amateur geologists, and other environmental scientists. This entirely new second edition represents the first detailed, comprehensive book on field geology in 20 years. Richly illustrated with 688 high-quality photographs and 300 interpretative sketches, this 704-page book is printed on glossy paper to show important strucutural and textural features. Contents include marine geological surveys, plutonic rocks, volcanic rocks, continental deposits, marine deposits, deformed rocks (joints, faults, folds, cleavage) weathering processes and soils, ground water, mineral deposits, and the public land survey system. The iterpretative sketches pull out the detail which you'd normally miss in the photos.

    Field Geology Illustrated, 2n Edition was designed to serve as a field reference to aid in recognizing, interpreting, and describing geologic features at the outcrop. Emphasis is on the study of mesocopic features that can be viewed at outcrop scale rather than large structures or landscapes. This book is not an exhaustive or comprehensive treatise on the subject of field geology, but instead cover the information necessary to understand and describe most outcrops...

    Field Geology Illustrated should be useful as a complementary text for any field-related geoscience course such as physical geology, field geology, petrology, and structural geology. The detailed descriptions, illustrations and photographs of geologic features in their field setting will be particularly useful (AG: on a field trip, vacation, or) where field trips are not feasible.

    This book is also intended for anyone who needs a good basic review of field geology including graduate students preparing for field mapping, professional geologists who wish to bring their skill up to date quickly and easily and even serious amateur geologists (AG: We believe this is useful to anyone interested in geology in the field!)Self study will be particularly rewarding because an interpretative sketch and detailed description is included with each photograph.

  • Mineral Hardness Scale Ruler

    The Mineral Hardness Ruler is a stimulating visual aid, educates in one phase of mineralogy, and provides the standard ruler measurement scales needed in classes.


    Rockhounds, mineral enthusiasts, students, teachers, geologists, and any one interested in rocks and minerals will find the Mineral Hardness Ruler a handy visual aid for quick information on mineral hardness.



    The two-sided, flexible, glossy, vinyl ruler consists of five scales: three measurement scales and two mineral hardness scales. The measurement scales are in standard ruler measurements of tenths of inches, sixteenths of inches, and millimeters. Mohs' relative hardness numbers are integrated into the inch scales, while a separate scale exists for an absolute mineral hardness scale by Rosiwal.


    On one side of the ruler are pictures of the ten common minerals, in full color, selected by Mohs for his relative hardness scale. On the reverse side of the ruler are six common items with their relative hardnesses. These items, along with known minerals, can be used as a handy field kit to test the relative hardness of an unknown mineral.


    Hardness is one property of a mineral that can be used to distinguish among similar minerals. A given mineral can scratch any other mineral of the same or softer hardness. Over a hundred years ago, the German mineralogist Frederick Mohs devised the relative hardness scale that has found favor with mineralogists for over a century. Others, such as Rosiwal, formed absolute hardness scales using the same minerals as Mohs. For example, diamond, the hardest substance in Nature is not twice as hard as apatite, 10 versus 5, but over twenty thousand times as hard, 140,000 versus 6.5.
