Hello Listers
I hop :) .... hope everyone had a great Easter...... I had peeps and pop corn and gummy worms, great combo.
I would like to announce the win and answer for the POP QUIZ today.
Question
True or False
The current classification scheme for meteorites had its
beginnings in the 1900s with G. Rose’s classification of the
meteorite collection at the University Museum of Berlin.
False
Correct answer is 1860's
I would like to congratulate Carl .... Meteoritemax. You will be receiving a Saratov fragment that fell in 1918 in Russia.
And while we are on the topic of classifications I found this early form of classification please take a look down below.
De Drée, 1803: The First Meteorite Classification
De Drée took a great interest in meteorites and
immediately began to work out a classification of them based
chiefly on their materials, as reported by Howard and
Vauquelin, and the circumstances of their falls. He
distinguished the following four classes (de Drée 1803b:410):
Class I: Stones consisting of similar materials that fell in
serene weather without thunderstorms: Salles, Ensisheim,
Barbotan, Benares, Wold Cottage.
Class II: Stones of the same materials as class I but which
fell from enflamed clouds with lightning flashes with or
without detonations: Siena, Tabor.
Class III: Masses mainly of malleable iron, of which the
only observed fall occurred at Agram in Croatia after a
fireball and an explosion followed by rumbling sounds.
Class IV: All masses for which the circumstances of fall
are not verified and their compositions fall outside those of
the first three classes or are uncertain: his list of about 20
included the irons found in Siberia, Argentina, and Senegal;
stones from observed falls including Lucé, Eichstädt, and
Portugal, and about a dozen historical accounts taken mainly
from Chladni.
