  1. CQL Virtual Program : Mineralogy of Bisbee with Doug Graeme and Richard Graeme

    October 26, 2021, 5:30 PM - 7:00 PM

    This is a virtual Zoom program.  

    Doug Graeme and Richard Graeme have just released their two volume set of The Mineralogy of Bisbee. Bisbee has produced tens of thousands of beautiful mineral specimens prized by collectors and institutions. Although, the mines are best remembered for producing rich glassy blue azurite, and velvety green malachite over 330 different mineral species have been identified from the mines. Bisbee is one of the most mineralogically diverse locations on Earth. Volume 1 examines the geology and mineralogy of the over 300 different mineral species that were largely created as a result of the formation of copper ore bodies. Special attention is given to the development of minerals in clay environments such as azurite cuprite andassociated rare species. A close look at post-mining, flourescence, and turquoise is included. Volume 2 is the descriptive mineralogy in which brief descriptions of the forms and locations in which these 330 minerals have been discovered at Bisbee.
