Tatyana Nikiforovna Chvileva

Tatiana Nikiforovna Chvileva (; 7 January 1925 – March 2000) was a Soviet and Russian mineralogist, petrographer and petrologist, candidate of geological and mineralogical sciences, developer of new methods for diagnosing minerals, active participant and author of the discovery of a number of new minerals. For more than 30 years, she has been a leading employee of the Moscow Institute of Mineralogy, Geochemistry and Crystal Chemistry of Rare Elements, developer of new methods for diagnosing minerals, mineralogist at the mineragraphy office.

During the 1970s — 1980s, Tatyana Chvileva co-authored the discovery of several new minerals, primarily bilibinskite, velikite, bezsmertnovite, gruzdevite and thallium-containing hakite. In 1988, a new polymetallic mineral, chvilevaite , found in Transbaikalia, was named in honor of Tatyana Chvileva; its composition is ferro-sulfide of sodium, zinc and copper with the formula Na(Cu,Fe,Zn)2S2. By decision of the International Mineralogical Association, Tatyana Chvileva was included in the encyclopedia of famous geologists and mineralogists of the world.

Tatyana Chvileva is the author of five monographs and more than eight dozen scientific articles. She made a significant contribution to the complex problem of diagnosing ore minerals and brought domestic science to a new level. Since the late 1980s, her definitive monographs have served as a textbook for students of Russian universities.
