Amorphous, dense, black, pitchy form of the crystalline uranium oxide mineral uraninite; it is one of the primary mineral ores of uranium. Pitchblende is found in granular masses and has a greasy lustre. Three chemical elements were first discovered in pitchblende: uranium, polonium, and radium. Deposits, frequently in association with uraninite or with secondary uranium minerals, are known in the Czech Republic, Britain, the Northwest Territories and Saskatchewan in Canada, and Arizona, Colorado, Montana, New Mexico, and Utah in the U.S.

pitchblende (pĭch'blĕnd'), dark, lustrous, heavy mineral, a source of radium and uranium. Largely natural uranium oxides, triuranium octaoxide (U3O8) and uranium dioxide (UO2), it usually contains some lead and variable amounts of thorium and rare-earth elements. It is massive in form, frequently with a botryoidal, or grape-cluster, appearance, and has a variable but high specific gravity. Pitchblende is greenish, brownish, or black in color, with a pitchy to submetallic luster. The uranium yield is from 50% to 80%. Uraninite, a closely related ore richer in uranium (uranium dioxide), commonly crystallizes in the cubic system. It yields 65% to 80% uranium and has a specific gravity somewhat higher than that of pitchblende. The color range is from deep black to brown. Both ores occur as primary constituents of quartz veins and with other metals. They supply radium and polonium in addition to uranium. Although the ores occur in small quantities throughout the world, the Great Lakes region of Canada, Congo (Kinshasa), the Czech Republic, the Colorado Plateau, Australia, and South Africa are the major sources.


Science Q&A: What is pitchblende?
Top

Pitchblende is a massive variety of uraninite, or uranium oxide, found in metallic veins. It is a radioactive material and the most important ore of uranium. In 1898, Marie and Pierre Curie discovered that pitchblende contained radium, a rare element that has since been used in medicine and the sciences.

Biography

Art punk quartet Pitchblende emerged in March 1991 from the same thriving metropolitan Washington, D.C., independent music scene home to the Dischord/TeenBeat/Simple Machines axis. Singers/guitarists Justin Chearno (a onetime member of Unrest and the Dustdevils) and Treiops Treyfid first met while working at a local bookstore, and made their earliest recordings as a duo, aided by a drum machine; after placing an advertisement in the Washington City Paper, they recruited bassist Scott DeSimon and drummer Patrick Gough, soon making their live debut under the name Comet Anger. As Pitchblende, the quartet recorded a ten-song demo tape that summer, and in early 1992 issued their debut single, "Sum," on the Landspeed label, moving to Jade Tree later that year to release the EP Weed Slam. Their full-length debut, Kill Atom Smasher, followed on Cargo in the spring of 1993, and Pitchblende toured the U.S. relentlessly in the months to follow, releasing their sophomore effort, Au Jus, in 1994. Early the next winter, Chearno relocated to New York City; when DeSimon followed a few months later, the group went on hiatus, although the foursome continued working intermittently on their third LP, GYGAX! (so named in honor of the creator of the role-playing game Dungeons & Dragons). Pitchblende officially dissolved following the album's release; Chearno and DeSimon later reunited in Turing Machine. ~ Jason Ankeny, All Music Guide

Pitchblende was a four-piece art-punk band from Washington, DC, featuring Justin Chearno on guitar, Scott DeSimon on bass, Patrick Gough on drums, and Treiops Treyfid on guitar. Between 1991 and 1995, the group recorded three full-length albums and several singles for independent labels Cargo, Jade Tree, Matador Records, and Simple Machines.

Style

Although based in Washington, DC, Pitchblende's dense, angular sound was commonly thought to be closer in style to contemporary music scenes in New York and Chicago than what one would hear on DC-based post-punk labels at the time. Central to Pitchblende's approach was an emphasis on experimentation and dynamics; the band's songs often featured complex structures, unusual arrangements, alternate tunings, and jarring time changes.

Pitchblende's recordings and loud, energetic live shows earned them critical accolades and comparisons with influential bands such as Mission of Burma and Sonic Youth. The group melded together the chaotic spirit of punk with an absurdist, dada aesthetic; somewhat pop sensibilities; and a musical proficiency informed by prog-rock bands. In spite of occasional references to being inspired by jazz, very little of Pitchblende's music was improvisational. This misconception prompted the band to cheekily rename itself The Pitchblende Quartet for its final 1995 album Gygax!

Breakup

Despite extensive touring and prolific recorded output, Pitchblende remained largely a favorite of critics and college radio. After a disastrous final US tour in 1994 when the band's gear was stolen in San Francisco and DeSimon was jumped and beaten up in New Mexico, Chearno and DeSimon moved to Brooklyn where they formed the three piece instrumental band Turing Machine. Chearno also went on to form the bands Doldrums and Panthers. These days, Chearno works in the wine industry in New York between recording and touring. DeSimon is a magazine editor. Gough is an urban planner in Northern Virginia who currently plays in Imperial China, and Treyfid is a Los Angeles-based fine artist, solo musician, and graphic designer.
