[Rockhounds] AD - Old Issues of "California Geology" for sale

[Jim Mills]

Hello Group

I am thinning out from my library some older issues of California Geology dating back to the late 1980s.  I am highlighting some issues below which contain an article which I think may be of interest to members of this news group and I have indicated that article in all caps for convenient scanning of the list.  Please note that all of the issues of California Geology from that era contained around 22 to 26 pages and I have indicated just the one article from each issue which I thought to be most of interest.  Each issue has several more articles besides the one I have identified.  The condition of these issues vary from MINT - could have been mailed yesterday to FAIR - missing the back cover and sometimes missing the back cover and a portion of the penultimate page (where a previous owner cut out the publication order form).  None of the articles I highlight are impacted by the lack of a back cover but of course, such a lack would make the copy more germane to information than to being "collectible".  In quite a few cases I had managed to find a library copy and make a Xerox of the back cover so all of the information for that issue is present.  If condition of the entire issue is important to you, please ask, off list, about the particular issues that are of interest and I will email the information back to you.  COST: I am asking a modest $6 per copy and for that price I will provide free shipping and cover the applicable CA sales tax myself.  My past offers of books out of my library have drawn immediate and extensive response and many people were disappointed.  I will post this advertisement to more than one newsgroup so if you are a member of some other groups as am I, you may receive multiple copies of the ad - for this I apologize.  If you see something of definite interest to you, or if you have questions, let me know quickly - OFF LIST to MillsGeological at hughes.net  Here are the issues and the article titles:

January, 1989 - VIVIANITE IN LITTLE LAKE VALLEY, MENDOCINO COUNTY, CALIFORNIA by Prokopovich and Cooke (two retired geologists). This article, of great interest to mineral collectors, gives a good description of the mineral, the area geology, and the locality (with very specific coordinates and directions and map) near Willits, CA. 

July, 1989 - CHESTERMANITE - A NEW MINERAL from Fresno County, CA by John Alfors of the Division of Mines and Geology. The article gives a good description of the mineral and the locality near Twin Lakes, CA. 

April, 1988 - COPPER MINING IN FRESNO COUNTY by Frank Lorey, Historian.  A 4 page article which discuses 4 copper mines in the Sierra foothills - the earliest one around 1875.

September, 1988 - VOLCANOGENIC MASSIVE SULFIDE BELT OF THE WESTERN SIERRA NEVADA FOOTHILLS by Roger Martin of the Division of Mines.  A 10 page comprehensive article on the copper and zinc sulfide mineralization belt of the foothills.  Well illustrated.

October, 1988 - GEOLOGIC RELATIONSHIPS ALONG THE SAN GABRIEL FAULT BETWEEN HARDLUCK CANYON AND CASTAIC by Harold Weber of the Division of Mines.  A 9 page article which makes this complex fault much easier to understand.  Really good maps.

March, 1989 - ORIGIN OF THE LAKE ISABELLA PLUTON AND ITS ENCLAVES by Lorence Collins, Cal State Northridge Geology Professor.  Some very interesting hypotheses about the origin of the Kernville Metasediments and the Isabella Pluton that extends from Lake Isabella to Walker Pass.  7 pages.

July, 1991 - GEOLOGY OF SANTA BARBARA ISLAND by Robert Norris of UC Santa Barbara.  There is very little in the literature on the geology of this, the most remote member of the Channel Islands National Park.  This 5 page article helped correct that omission!

December, 1988 - MYRMEKITE - A MYSTERY SOLVED NEAR TEMECULA by Lorence Collins of Cal State Northridge.  If you are interested in petrology, this is an excellent treatment of the obscure mineral textured myrmekite in 6 pages.  Issue also has good summary of Geology of Del Norte and Siskiyou counties in the far north of the state.

July, 1988 - CYANIDE HEAP LEACHING IN CALIFORNIA by Michael Silva with the Division of Mines.  A 10 page article which very clearly and concisely explains the process by which gold and silver are now recovered at the big open pit gold mines in the West.  

January, 1988 - ELEMENTAL ANALYSIS OF MICA RESOURCES IN CALIFORNIA by James Post of Cal State Northridge.  If you favor collecting in pegmatites and have wondered about the excellent mica "books" in these deposits, this 11 page article will fill you in on mica mining in California and the mineralogy of its paragenesis.

June, 1986 - RANCHO LA BREA: A LOOK AT COASTAL SOUTHERN CALIFORNIA'S PAST by Christopher Shaw of the Page Museum and James Quinn of the LA Natural History Museum.  An eleven page article highlighting history of the dig and paleo-ecology of the area at the time of deposition.  Comes with a nice bibliography of this famous dig site.

July, 1986 - SINGING AND BOOMING SAND DUNES OF CALIFORNIA AND NEVADA by Dennis Trexler of Univ Nev Reno and Wilton Melhorn of Purdue Univ.  This is a fascinating 6 page article explaining the origin of the acoustic noises produced by shifting sand in dunes.  Nice summaries of each sand dune area in the two states that exhibit this interesting phenomenon.

August 1986 - MAGNETIC EXPLORATION FOR SKARN DEPOSITS - IVANPAH MINING DISTRICT, SAN BERNARDINO COUNTY by Chapman, Joseph and Campbell plus MOUNT BALDY MINING AREA by D Trent of Citrus College.
