The Del Air Rockhounds Club Welcomes You!!






The Del Air Rockhounds Club was founded in 1952 with members mostly residing in the San Fernando Valley area of California. Our club is a non-profit organization dedicated to sharing knowledge of the lapidary arts and techniques, geology, mineralogy and related fields. We own our own lapidary equipment with members available to teach and demonstrate lapidary techniques to other members. Our members enjoy lapidary related programs, demonstrations, exhibitions, displays and lectures. We also take monthly field trips to our local deserts & mountains for exploration and the study and collection of lapidary and mineral specimens.

April 2014 Program:

“Basic Mechanisms of Agate and Jasper Formation”
By: Donald Kasper
What a great opportunity to have Donald Kasper, a knowledgeable and talented author of 18 books, present “Basic Mechanisms of Agate and Jasper Formation” at the Del-Air Rockhounds Club April 2014 general meeting.  He will describe set conditions that constrain how these silica rocks form and how they are related to volcanic systems.  Some of the findings using infrared spectroscopy to identify agate structures and inclusions are discussed, as well as the composition of some commonly sold agates.  The goal is to show that agates and jaspers do not form from weathering, but instead form in specific geologic systems that we can search successfully ourselves in the public lands of the Southwest. Donald’s book on infrared identification of the major agates, jaspers, opals, and geode structures of the world will be shown.  His latest book detailing a study of the California coastal agates, which are influenced strongly by marine conditions, will be shown for the first time. Donald will take you on a high-level, basic tour of how some of these complex structures form as he continues on his theory of how water affects these silica systems which produce the agates that we collect.  You may also bring some specimens for Donald to identify!  Please visit Donald’s website at www.DonaldKasper.com.
