Extractions: Lunar mineralogy Introduction Samples brought back by the lunar missions Main lunar minerals Introduction One of the major problems encountered by mineralogists studying lunar mineralogy is due to the scarcity of lunar materials likely to be studied. Two sources of rocks and lunar minerals exist indeed, they consist in: 1) samples brought back by the lunar missions 2) meteorites of lunar origin fallen on Earth. Samples brought back by the lunar missions: An overall weight of 382 kilograms (= 842 pounds) of various moon rocks forming 2196 samples were brought back from the Moon by the 6 American missions of the Apollo program having reached the Moon between 1969 and 1972. We must add to that weight approximately 300 grams (3/4 of pound) of moon rocks brought back by the 3 Russian missions of the Luna program. These samples contributed to a better knowledge of the Moon and about the early formation of the solar system. One of their main interests is to have been dated by radioisotopic methods. The NASA Johnson Space Center located in Houston (Texas, U.S.A.) is in charge of the preservation of the lunar samples brought back by the American missions as to prepare samples which can be studied by scientists. On the whole, 97,000 catalogued samples were prepared by the Johnson Space Center facilities for study and analysis. Even today, more than 25 years after the lunar missions, scientists belonging to more than 60 laboratories through the whole world continue to study lunar samples. This requires for the Johnson Space Center to prepare and send to the researchers more than 1,000 samples every year. Studied samples remaining non destroyed or undamaged by the analyses are send back to NASA and reconditioned for a later re-use.
Extractions: The beginnings of modern Mineralogy: from the end of the XVIII th century to the middle of the XX th century. Crystallography: from the geometrical study of crystals to X-ray crystallography. Today, a great importance is given to the study of the crystal lattices defects. The knowledge acquired in mineralogy finds immediate applications in other disciplines, in particular metallurgy and materials science. To give a recent example, it is interesting to note that the structures of the first " high temperature " supraconductor materials were determined by mineralogists of the Geophysical Laboratory at Carnegie Institution (Washington D.C., U.S.A.). Doing that work they participate in a decisive way in one of the greatest adventures of modern physics. Chemical properties A mineral is defined as a natural body with an ordered structure - in rare exceptions some minerals possess a vitreous structure, such as the natural glass known as lechatelierite- and with precisely codified chemical composition: constant for a certain number of relatively simple species (SiO2 for quartz, CaCO3 for calcite, etc)

Extractions: FAQ ... Equiv Manual Description The Equiv program allows for the analysis and management of data collections from X-ray single crystal diffractometry (namely, a generally large set of hkl indices, together with the corresponding diffraction intensities, or structure factor, and standard deviations). It is particularly useful for high symmetry systems, where a checking of the intensities of the equivalent reflections is a good and fast way of estimating the quality of the data collected. Since the publication of the release 1.0 of the program, a number of upgrades have been done and a new graphical interface has been developed. Download The new 2.0 release (1/05/03) of equiv is now ready for download. The program has been extensively tested on a Linux based platform (kernel 2.2.17) but it can run on every Unix or DOS/Win based system.
