LAST ONE OF THESE!! LIKE MANY GREAT TITLES, I'M RUNNING OUT!!
This is USGS Bulletin 936-K,
Tin deposits of Irish Creek, Virginia.
This locale is in Rockbridge County. Published in 1942, there can't be many of these around. The publication consists of a 26-page book and both of the original maps, which are foldout maps within the book. This is a very interesting area that contains the following cool minerals:
Cassiterite
Beryl
Ilmenite
Siderite
Ankerite
Fluorite
Phenakite
And other minerals!
This is a relatively compact area with all the workings occurring in an area about 3000 feet long, so the maps are quite specific as to the locations of veins, making this a pretty valuable tool for the mineral collector that wants to give this area a try. The tin veins were mined with trenches and underground workings and there are maps of those workings. The photo shows the book with one of the foldout maps extended. The map is of one of the underground workings. This book would make a great guide for prospecting this interesting mineralized area.
Some very nice crystals of cassiterite have been found at this
locality
. It is probably one of the best cassiterite locations in the US.
A rare and desirable geologic publication on an interesting mining area and it is in excellent condition.
Expert packing assured. The recent increase in postage rates was pretty big. As a result, Media Mail is now my default shipping method to keep shipping affordable.

CLASSIC REPORT ON PORPHYRY SKARNS!!
This is USGS Professional Paper 798-C,
Geology and Geochemistry of the West Ore Body and Associated Skarns, Copper Canyon Porphyry Copper Deposits, Lander County, Nevada.
Published in 1978, this is a scarce work, seldom seen or offered on Ebay, because mining companies gobble these things up. It consists of the 84-page book and the original map, plus many diagrams in the text.
This location is the same as the Phoenix mine that currently produces gold, copper and silver, but it was written before the phoenix mine developed. The West Ore Body was in the north end of the current mine and had high grade copper ores and extensive garnet skarn. This report details it all and is nice for having a more modern understanding of skarns, porphyries, and the chemistry of alteration processes. It is interesting and essential reading on the porphyry-skarn mineralizing environment. Written by Ted Theodore and David Blake. More important than ever since all the rocks in the West Ore Body area have since been consumed by later mining. An absolute classic.
Expert packing assured.
Shipping weight is one pound.
