As one of those poindexters who actually likes to watch Book TV on C-SPAN-2, I blundered into an interview of Naomi Prins. The host was Senator Bernie Sanders (I-VT). Prins is presently a Senior Fellow at Demos and has had careers at Goldman Sachs and Bear Stearns.

Prins has a good deal of interesting insight into how securities are engineered from subprime loans and stamped with ratings. What stands out is how artificial securities are as an asset. It’s like putting a step ladder on a canoe. The view is good, but evenually you’re going to get wet.

Securities are synthesized from dung and straw, drenched in investment sauce, and then nestled in decorative tins by white gloved MBA castrati to afford a “product”. Naturally, banks and ratings agencies assure us that the rating on the security is meaningful. After all, who is more sober and conservative than a banker?

Perhaps investment banking as it is now practiced should be regarded as a pathological condition- a form of predatory, sociopathic behavior worthy of a psychiatric profile? Investment banking is a profession dedicated to the proposition that the mere repackaging and skimming of the wealth of others is the desired outcome. It is a bubble industry specializing in puffery and deception.

My libertarian friends assure me that the free market place is the most natural and efficient form of economic intercourse. Of course, the problem is that there isn’t a substantially free market anywhere. We have regulated markets because some people invariably game the system at the expense of others, resulting in a convulsive discharge of legislation.

One could take a Darwinistic view and say that the victims of investment shenanigans are to blame for being greedy and uninformed. There is truth in caveat emptor, but one of the reasons we have civilization is to buffer out the harshness of life. How do you protect the greedy and uninformed from the greedy and deceitful? It is the eternal problem.

The most despicable part of the 2008-9 financial collapse is the lack of accountability on the part of the skunks who invented and promulgated the unstable investment devices.  Their heads should be impaled on sticks and planted in the financial districts for all to see. Figuratively, I suppose.

This year we tried Tofurky along with turkey for the thanksgiving meal. While my expectations were low, I have to admit that the Tofurky wasn’t quite as nasty as I had imagined. It is a seitan/soy product textured to resemble meat. Truthfully, in texture it resembles a firm bologna or salami lunchmeat. The package recommends that it be sliced thinly.

One plate holds a Tofurky. Can you tell which one it is?

Buried in mashed potatoes and real turkey gravy, the Tofurky was moderately edible. It is hard to say just how thankful the pilgrims might have been if Squanto had brought Tofurky to the feast. I’ll wager that the soiree would have gone badly.

Recently I came upon a copy of Geological Survey Circular 186, 1952, F.B. Moore and C.R. Butler, Pitchblende Deposits at the Wood and Calhoun Mines, Central City Mining District, Gilpin County, Colorado. Like many Geological Survey documents, it contains a pocket with neatly folded scale drawings of the mine workings. These drawings chart the location and elevation of the shafts and drifts and give a best estimate as to the extent of the formation.

What is interesting about the map above is not so much the minute detail of the locations, but rather the obvious trend of the veins (solid lines with dots).  They are all east-northeast trending.  The country rock is largely precambrian granite gneiss and quartz biotite schist according to the survey. It doesn’t take long to figure out that the mine locations correlate with the veins.

Geological Survey maps of 3 levels of the Wood Mine, Gilpin County, Colorado (Geological Survey Circular 186, 1952).

The second figure was generated by Moore and Butler in 1950 and shows the locations of pitchblende occurrences in three levels of the Wood Mine near Central City, Colorado. The red dots indicate the location of pitchblende along the three drifts at the 135, 197, and 275 foot levels of the mine.

 The Wood Mine was an early and prolific source of pitchblende, though presumably it began as a gold /silver operation. The workings reportedly reached a depth of 600 ft.  The Wood vein is in a fault fissure that shows extensive alteration from hydrothermal action. The width of the vein varies with the type of country rock in which it is found, but ranges from from 1 to 18 inches and has been followed for a lateral distance of nearly 1000 ft.

The productivity of uranium mines is commonly expressed in terms of equivalent weight of U3O8 rather than weight of ore, given the large variety of mineral forms uranium is found to occur in. The figure above is from Geological Survey Professional Paper 371, P.K. Sims and collaborators, Geology of Uranium and associated Ore Deposits, Central Part of the Front Range Mineral Belt, Colorado. Extensive stoping has been done in an attempt to vertically intercept the vein. This was a common practice in hard rock mining- let gravity bring the muck to you.

Pitchblende was discovered on the dump of the old Wood shaft in 1871. Circular 186 reports that by the end of 1872, 6,200 lbs of ore containing 3,720 lbs of U3O8 had been removed. By 1916, 102,600 lbs of ore bearing 30,040 lbs of U3O8 equivalent had been recovered.  The high grade pitchblende was hand sorted and that below ca 10 % was discarded or lost in gold and silver processing.

In Circular 371, Sims observes that ”Pitchblende occurs as small, discontinuous lenses and streaks on the footwall of the Wood Vein, which are separated by nonuraniferous vein material.”

What is intriguing is that pitchblende was apparently an item of commerce in the early 1870’s. Radium, extracted from pitchblende, was not discovered until 1898 by the Curies.  A procedure for the preparation of sodium diuranate, Na2U2O7 6H2O, was reported as early as 1849 (Patera, J. pr Chem. 1849, [i] 46, 182. Early uses of uranium yellow were in paints and stains for glass and porcelain. This pigment has also been used for the production of fluorescent uranium glass.

Sunrise in the Fog (Nov 2009, Th' Gaussling)

Okay, I’m not Ansel Adams. I’m posting this only because I’m surprised that my inexpensive camera resolved the lamp as well as it did.  It is amazing how fast the lighting can change and the moment vanishes. I suppose there is a metaphor there.

The Palin phenomenon is an exercise in manufacturing consent. It is happening before our eyes. The GOP media machine is tunneling under the democratic ramparts and allowing the gravity of doubt to bring the walls crashing down.

While the conservatives are beavering away underground in the muck, the eternally frenzied media is handing the conservatives exactly what they want- air time on the talking points of their choosing. Since media people view the world as an everlasting stream of dramatic sequences, they are naturally drawn to the Palin freakshow like flies to a steaming road apple.

An electorate that put GW Bush in office twice is certainly an electorate that could be moved to put Palin in office. A President Palin wouldn’t be the end of the world, 2012 allusions aside, but it would definitely be emblematic of US culture. And that’s an emblem I would rather not wear.

The YouTube video below is a reconstruction of the flight of US Airways Flight 1549, referred to as Cactus. It is interesting to note how the pilot acted to conserve his altitude by careful energy management. After the dual engine flameouts the pilots established an optimum glide to maximize flight time. They did not bank the aircraft anymore than they had to- banking without power consumes altitude. While one pilot was flying the airplane the other was consulting the manual for emergency restart of the engines. The captain evidently knew right away that the only option for maximum survivability was to set the plane in the river.

Near the end the pilots found themselves coming in a bit fast so they brought the nose of the aircraft up and porpoised ~250 ft or so before locking on 130 kts indicated for their glide to the surface. They were mindful of bringing the aircraft to the site of the accident as slowly as possible. KE = (1/2) mv^2. 

Note how he dips the tail in the water first while keeping the wings absolutely level. This brought the aircraft into the water along the longitudinal axis and thus averted a cartwheeling accident. The engines become powerful drag devices once they are in water.

Let’s try it again-

11 November 2009.  Rhodium prices continue to rally on the EIB market, opening today at US$2,100/toz.  The economic downturn of 2008/2009 lead to a dramatic collapse in rhodium prices. Rhodium crested at US$10,100/toz in June of 2008, only to fall to below US$1,000/toz by early December of that year. By early October of 2009, prices began to show signs of buoyancy.

Rhodium demand is strongly tied to the health of the automobile industry, with ~85 % of production going towards automotive use. Approximately 84 % of rhodium production comes from South Africa where a handful of mining companies operate in the amazing Bushveld Igneous Complex near Johannesburg.

Ruthenium prices remain flat at US$95/toz.

As a kind of hobby Th’ Gaussling has been surveying the literature on uranium occurrences in North America. Uranium is found in many interesting locations and as a result of several distinct kinds of ore forming processes.

From Ballard &Conklin, Uranium Prospectors Guide, 1955 Harper & Brothers

For the most part, uranium ore body formation is the result of aqueous transport and deposition.  Uranium is found as a lode in vein formations in precambrian  igneous/metamorphic structures as in the case of the Schwartzwalder mine near Denver. In fact, there are many lode occurrences that contain a variety of uranium minerals in the Colorado mineral belt.

What seemed counterintuitive to me was the extent to which uranium is found in sandstone. Evidently I had developed a bias for connecting heavy metal occurrences with igneous/metamorphic formations.

Uranium occurrences in sandstone take on certain characteristics as a result of ore forming processes. Uranium is often found in concentrated bodies called “roll fronts” or “ore rolls”. A roll front is a body of concentrated mineral with a lenticular cross section and is found in confined strata sandwiched between impermeable clays, shales, or mudstones.

Adler & Sharp, Guidebook to the Geology of Utah, No. 21, Utah Geological Society, 1967, p. 59.

The action of oxygenated meteoric water (i.e., rain and surface water) migrating through a porous sandstone stratum will selectively mobilize mineral species that are soluble. In the case of uranium, the relatively insoluble U4+ compounds are oxidized to more soluble U6+ species which are then mobilized and flow in the formation.

Eventually, as the water flow encounters reducing conditions, U6+ gets reduced to U4+ and deposition occurs. Sandstone with organic material may be a net reducing environment and provide the necessary carbonaceous reductants to do the deed.

As the U6+ enriched aqueous flows encounter reducing conditions, deposition of U4+ insolubles occurs in a manner determined by fluid mechanical forces. The result is an elongated and tapered ore body confined to a narrow stratum.

Uranium roll fronts are common in many uranium districts. The Uravan uranium belt in the Colorado Plateau is a good example. Uranium is found concentrated in tuffaceous formations as well. An example of this is the uranium occurrence found in the 39 Mile Volcanic Field in the central Colorado mountains.

What is interesting to ponder is the geological effect of plant metabolic byproducts like oxygen. Oxygen directly contributes to a natural process that lead to the concentration of a scarce element like uranium. Plant life facilitating nuclear power. Hmmm.

I just received the sad news that my friend, boss, and mentor, Dr. Irwin “Ike” Klundt died in Tucson, AZ, of cancer. Ike retired in the early 1990’s as VP of Sigma-Aldrich. He was an organic chemist from eastern Washington state. He joined Alfred Bader in the 1960’s (?) and helped build Aldrich into what is is today. He started the Aldrichimica Acta and appeared in it many times in the capacity of awarding a prize to honor prominent chemists. Ike also managed the publication of the catalog and invented the Aldrich “Coffeepot” Kugelrohr.

I first met Ike when I taught for a year at Ft Lewis College in Durango, CO. He was an adjunct prof and I was a visiting prof. Ike was loved by all and was a useful hand to have around for the department.

Ike was a good hearted soul who enjoyed the company of others and actively worked to help younger chemists develop their careers. He loved the science and business of chemistry and the people who worked in this field of ours. Ike was forced out of Aldrich soon after Bader was given the boot as the once entrepreneurial company began to behave like a normal publicly traded company- you know, the ones that eat their young.

The chemical field is poorer for the loss of Ike Klundt. He was one of the human beings of the trade and he will be missed.
