ME-594 MBALE, UGANDA - Stone.
Chondrite (L5-6) "CM" REF: None - NEW! "ARN’S" REF: P. 193.
On August 14, 1992, at approximately 15.40 hours East African time, the residents
of Mbale town and its outskirts were frightened by several loud detonations in the sky.
Mbale is located in eastern Uganda, about 250 Km east of Kampala. Eyewitnesses reported
seeing a trail of smoke behind the meteoroid body, but no fireball was observed. A map,
showing the location of the fall and the distribution of individual meteorites within an
elliptical strewnfield, will be sent with each order for a specimen from this witnessed
fall. The strewnfield covers an area of approximately 20 square Km., and approximately 108
Kg, (approx. 426 stones) have been recovered. About 50 impact localities were found. Most
of the Mbale material is now kept in Uganda, and at two universities in Europe. The Mbale
meteorite’s stone matrix is fine-grained, with a very light gray color. It contains
silvery metallic specks of NiFe, and some Troilite, as well as many glossy black shock
veins. Fusion crust is black with a thickness of about 1 mm. The specimens listed below
are complete individuals, with the black fusion crust intact over
most of the surface of each specimen, Each is individually priced according to the
completeness of the fusion crust. All are in excellent, very fresh, natural condition, as
field collected in 1992. For additional information, see the write-ups of the Mbale fall
in "Meteoritics", March 1994 (Vol. 29, No. 2), P. 246-254, as well as July 1994
(Vol. 29, No. 4), P. 496 and 519.

McKenzie Draw (b), Texas H) 34.83 grams
|
ME-595 McKENZIE DRAW (b), GAINES COUNTY, TEXAS, USA - Stone.
Chondrite (H4). “CM” REF: None (NEW!). Found: 1989, Summer -- recognized as a
meteorite: 1991. Two distinctly different individuals were found in the same area as the
McKenzie Draw (a), described under item ME-573. These were both determined to be H4
stones, yet the MeKenzie Draw (a) and (b) have markedly different appearances! Information
on both (a) and (b) appears in “METEORITICS”, Vol. 27, No. l, March l992, P.
ll3. All specimens offered here were supplied by Terry Schmidt of the Tiara Observatory,
who was responsible for helping to authenticate these finds, and for providing the
write-up for “METEORITICS”. A Xerox copy of the information from
“METEORITICS” will be sent with each specimen ordered. The McKenzie Draw (b) has
a mottled, red-brown to brown-black matrix with scattered, limited distribution of small
metallic flakes. Thin, metallic gunmetal black color micro veinlets are very obvious over
the cut and polished surface of each specimen. Chondrules are light gray-tan in color. All
examples are slices, with the exception of items F) and I), which are end cuts. The cut
and polished surface on item I) was prepared on one end of the specimen, and the fusion
crust is present over a portion of the back of the specimen. All examples show a portion
of the reddish-brown fusion crust, except items A) and J). The edges of the slices without
fusion crust have natural, irregular surfaces -- no saw cuts. Pricing is at +/- $6.00 per
gram, which is quite reasonable considering the rarity of this H4 (only two individuals
found, total weight 2.99 kg.).

St. Lawrence, Texas B) 21.74 grams

ME-596 ST. LAWRENCE, GLASSCOCK COUNTY, TEXAS, USA - Stone.
Olivine-hypersthene chondrite, amphoterite (LL6). “CM” REF: P. 309.
“ARN’S” REF: P. 274. Found: 1965. In “The Meteorite and Tektite
Collector’s Handbook”, P. M. Bagnall, P. 77 (1991), a table shows the relative
proportions of finds/falls known, among the various meteorite groups. Among the
chondrites, the LL group (amphoterites) accounts for only 8.4% of the total number of
recorded chondrites. The LL classification is given to this small group of chondrites
which are low in iron, and low in metal content. Found in 1965, the single specimen of the
St. Lawrence, Texas amphoterite weighed only 2.6 kg. It was described in
“METEORITICS”, l970, Vol. 5, P. 175 and, with the exception of the listing in
the “Catalogue of Meteorites”, P. 309, no additional research data could be
found on this LL6. The lack of information can probably be ascribed to the limited
distribution of this find in collections, since the single stone found weighed only 2.6 kg
which, previous to 1992, had been held in the collections of only five institutions,
according to the “CM”. The two specimens available are both part slices, each
with three saw cut edges. One surface of each slice has been polished to show the details
of the stone matrix, as well as the bright, very fresh pinpoints of included metal. Item
A) is a center cut, without fusion crust, priced @ +/- $6.00 / gram. Item B) has one
exposure of the very thin, unweathered, reddish-brown fusion crust, as pictured, priced @
+/- $7.50 / gram.
