By L. FLETCHER, M.A., F.R.S., Keeper of Minerals in the British Museum. (With a Map of the District, Plate X.) [Read March 12th and May 7th, ]889.J 1. THE immediate object of the present paper is to place on record J- the history and characters of several Atacama meteorites of which no description has yet been published; but incidentally it is con- venient at the same time to consider the relationship of these masses to others from the same region, which either have been already described, or at least are stated to be preserved in one or more of the known Meteo. rite-Collections. 2. The term " Desert of Atacama " is generally applied to that part of western South America which lies between the towns of Copiapo and Cobija, about 330 miles distant from each other, and which extends island as far as the Indian hamlet of Antofagasta, about 180 miles from 224 L. FLETCHER ON THE METEORITES OF ATACAMA. the coast. The Atacama meteorites preserved in the Collections have been found at several places widely separated throughout the Desert. 3. A critical examination of the descriptive literature, and a compari- son of the manuscript and printed meteorite-lists, which have been placed at my service, lead to the conclusion that all the meteoritic frag- ments from Atacama now preserved in the known Collections belong to one or other of at most thirteen meteorites, which, for reasons given below, are referred to in this paper under the following names :-- 1.

    — THE METEORITE COLLECTION IN THE U. S. NATIONAL MUSEUM; A CATALOGUE OF METEORITES REPRESENTED NOVEMBER 1, 1886, By F. W. Clarke. The following catalogue has been prepared mainly to facilitate ex- changes and to aid in the upbuilding of the collection. In addition to the usual information as to title, date of fall, and weight of specimen, it has beeu thought well to give the source from which each example was obtained ; and it may be interesting to note that the meteorites ac- credited to Dr. J. Berrien. Lindsley were mainly received by him from the late Dr. J. Lawrence Smith. In the catalogue of the Shepard col- lection, now on deposit in the Museum, the arrangement of Professor Shepard himself has been followed without change. Including the Shepard meteorites, over 200 falls are now on exhibition, giving the entire collection a very respectable place among the larger collections of the world. The Tucson iron is unique, and therefore a cut of it is inserted. METEORIC IRONS. 1. Scriba, Oswego County, N. Y. Fouud about 1834. Fragment, 9.15 grammes. By exchange from S. C. H. Bailey. 2.

S. National Museurn, Washington,D.C. INrnorucuoN The fall of meteorites from heaven has been a recognizedphenomenon for many centuries. It is stated that the first record is one among the Chinese 6,000 years ago. The Persians, Greeks and Romans considered them as messagesfrom the Gods, built temples over them and revered them. During the Middle Ages they were looked upon as omens of evil, bewitched personagesand similar prodigies. Later, a belief in the possibility of stones fallen from heaven brought forth only ridicule, gven from scientific men. Stiitz, a famous Austrian mineralogist, remarked, concerning the reported fall of a mass of pure iron at Agram in 1751,that "in our times it would be unpardonableto considersuch fairy tales even probable." The German physicist, Chladni, in 1794first challenged this disbelief and even suggestedthat meteorites are, in fact, "world fragments." Mineralogists now recognizedthem for what they are-celestial rocks-rocks with many unusual characters, but amenable to study by the same methods as the better known ter- restrial rocks. The earliestpreserved meteorite is one that fell at Ensisheim,Germany, on November 16, 1492.Since then 1,250 distinct meteoriteshave been recovered,some only as a small individual of but a few grams, others very much larger, even weighing tons. Some reach the earth in thousands of fragments as a shower of stonesduring a single fall, as those of Pultusk in 1868, when 100,000fragments are said to have fallen.

Smithsonian Contributions to the Earth Sciences, 3:1—17. 1970.—Nickel-iron, troilite, olivine, pyroxenes, plagioclase, chromite, and phosphate minerals (chlor- apatite and/or merrillite) have been separated from a number of meteorites (Modoc, St. Severin, Winona, Haraiya, Marjalahti, Springwater, Johnstown, Mt. Egerton, Soroti) and analyzed for minor and trace elements with the spark-source mass spectrometer. The elements Ni, Go, Ge, As, Ru, Rh, Pd, Sn, Sb, W, Re, Os, Ir, Pt, and Au are concentrated in nickel-iron: Se and Ag in troilite; Th, U, and the lanthanides in the phosphate minerals and in diopside; Eu, Sr, Ba, Rb, and Gs in plagioclase. Molybdenum and tellurium are concentrated in nickel-iron and troilite. The elements Ti, Sc, V, Cu, Zn, Mn, and Ga are distributed over several coexisting minerals. Official publication date is handstamped in a limited number of initial copies and is recorded in the Institution's annual report, Smithsonian Year.

  • Parauapebas Meteorite from Pará, Brazil, a “Hammer” Breccia Chondrite
    SILEIR RA A D B E E G D E A O D L E O I G C I A O ARTICLE BJGEO S https://doi.org/10.1590/2317-4889202020190085 Brazilian Journal of Geology D ESDE 1946 Parauapebas meteorite from Pará, Brazil, a “hammer” breccia chondrite Daniel Atencio1* , Dorília Cunha1 , André Luiz Ribeiro Moutinho2 , Maria Elizabeth Zucolotto3 , Amanda Araujo Tosi3 , Caio Vidaurre Nassif Villaça3 Abstract The Parauapebas meteorite, third official meteorite discovered in the Brazilian Amazon region, is a “hammer meteorite” which fell on De- cember 9th, 2013, in the city of Parauapebas, Pará State, Brazil. Mineralogy is dominated by forsterite, enstatite, iron, troilite, and tetrataenite. Albite, chromite, diopside, augite, pigeonite, taenite, and merrillite are minor components. Two main clasts are separated by black shock-in- duced melt veins. One clast exhibits an abundance of chondrules with well-defined margins set on a recrystallized matrix composed mostly of forsterite and enstatite, consistent with petrologic type 4 chondrites. The other clast displays chondrules with outlines blurring into the groundmass as evidence of increasing recrystallization, consistent with petrologic type 5 chondrites. The clasts of petrologic type 4 have a fine-grained texture compared to those of type 5. It is a genomict breccia (indicated by shock melt veins) with the clasts and matrix of the same compositional group, but different petrologic types, H4 and H5. The melted outer crust of the Parauapebas meteorite is comprised of forsterite with interstitial dendritic iron oxide, and is rich in irregular vesicles, which are evidence of the rapid formation of the crust. The type specimen is deposited in the Museum of Geosciences of the University of São Paulo, Brazil.
