There is a USGS Professional Paper - Geology and Quicksilver Deposits, Terlingua District, Texas, Geological Professional Paper 312 by Yates and Thompson (1959) Doug Thayer 338 Potrillo Drive Los Alamos, NM 87544 (505) 672-9743 -----Original Message----- From: mining-history [mailto:[log in to unmask]]On Behalf Of JOHN BERRY Sent: Thursday, May 08, 2003 2:33 PM To: [log in to unmask] Subject: Re: aerial ropeways; Texas silver/mercury mining. I will also have photos (touch wood) in a couple of days of one of the Mercury mines near Terlingua, TX, and of the Silver mining ghost town of Shafter, TX, if anyone is interested. Can send references on Terlingua. Would be interested if any of the N. American members of the list have references to the geology of either mining district - I think there's some TX BEG stuff on Terlingua, but most work was proprietary. Both districts are some sort of replacement or open-space filling in limestone: plenty of igneous activity in the district, but no obvious source of the hot waters. The mercury deposits are pre-large scale faulting, and I have a book that te! lls the story of the geologic inference used to find the off-set portions, but the book is by a historian and contains no maps or cross-sections. Apparently Goldfields controlled Shafter until 2 years ago.

Download takes about 5 minutes for a 50second video of working system.There also used to be an aerial ropeway in north Kent at Bowaters Papermill Kemsley Sittingbourne, it ran about 3 miles to the docks at Ridham and was used for carrying pulp and pulpwood.I think it went out of use in the 70s but as far as I can remember is still in situ. It should be visible from the A249 at Kingsferry bridge onto the Isle of Sheppey.
