[meteorite-list] Statistically Speaking (Vaca Muerta)

[MexicoDoug]

Hi Bernd;

Wow, that's a great passage!

And here's one of the maps it refers to (as I mentioned from Rodrigo's 
old site) - not sure which - probably Fletcher (1889) if picking from 
your reference's descriptions:

Don't know if the link will work but be sure to paste it together in 
the URL bar of the browser without changes introduced by the email 
spacings; here's the map with "Llano de la Vaca Muerta" SE of Taltal...

Kindest wishes

Hi Ruben, Doug, AL, All ;-)

PEDERSEN H. et al. (1992) Vaca Muerta mesosiderite strewnfield
(Meteoritics 27-2, 1992, 126-135, Appendix A: Synonyms, p. 134):

As often happened with meteorite finds from the last century, the 
material
was assigned a variety of names. In the case of Vaca Muerta, this is
particularly
understandable, since the meteorites were collected over a long 
interval of time
and from a sparsely populated area.

Some of the material passed through several hands, during which specific
provenance information was lost. Nevertheless, the synonyms listed for
Vaca Muerta (Graham et al., 1985) offer a source of information on the
location and size of the strewnfield.

The most interesting are probably those discussed below. Others are too 
vague
to be of value (Chañaral, Taltal, Chile) or even misleading (Sierra de 
Chaco,
Mejillones, San Pedro, San Pedro de Atacama, Harvard University).

Vaca Muerta (i.e., Dead Cow), Quebrada de Vaca Muerta: This name is 
first used
by Domeyko (1875). As a geographical location, it appears in print only 
rarely.
On a map studied by Fletcher (1889) and on one published by Espinoza 
(1897),
Llano
de (la) Vaca Muerta, is a plain, south or south-east of Taltal. In 1883 
a number
of rich silver mines were discovered in the coastal mountains of that 
area.

One of them was initially known as Vaca Muerta (Vicuñia Mackenna, 1883;
Fletcher,
1889; Domeyko, 1897), but soon it received the "glorious name 
Esmeralda" (San
Ramon, 1911).

Finally, six named meteorites are marked on a map of mines in the 
provinee of
Antofagasta, hand-drawn by Emilio Arnes, in 1934. Vaca Muerta is 
plotted as a
position about 30 km north of the place where we found the largest 
masses.
Sundt (1909) says that he saw the meteorites near a hill called Burro 
Muerto
(Dead Donkey).


Best wishes,

Bernd
