   ALLENDE

Country:Mexico
State/District:Chihuahua
Coordinates:
Date of fall/find:1969
Total known weight:2 ton.


Type:CV3


StoryChihuahua, Mexico was rocked by a tremendous rain of stones on February 8, 1969. Thousands of stones both large and small fell in a wide area. These stones would quickly be recognized as a rarer type of chondrite called Carbonaceous.These would have characteristics unique to a subclass the Vigarano type. They are rich in large chondrules and scattered through the matrix are irregular masses called Calcium Aluminum Inclusions or CAIs. Allende also contains microscopic diamonds that are among the oldest particles ever discovered.

Country:Peru
State/District:Puno

Date of fall:2007
Total known weight:342 gr. (approx.)


Type:Chondrite H4-5


Story:
On September 15, 2007 a meteoroid entered the atmosphere over Lake Titicaca near the border of Peru and Bolivia. But, this was a most unusual event even for meteoroids. Normally a body the size of this one would detonate from the stresses of its tremendous velocity and the air pressure against it. This body however, appears to have been traveling at a strangely slow speed for a cosmic body. It reached the ground intact and created a crater something not normally done by chondrite meteorites. In doing so it destroyed itself into only small pieces. Carancas is a H4-5 type and quite friable. This crumbliness is also hard to explain for a body that reached the ground in one piece. This crater forming chondrite is certainly one of the most interesting new meteorites available for collectors.
