A new lunar meteorite has been discovered in the Antarctic. The meteorite is labeled EET96008. It was discovered in the Elephant Moraine region in the Antarctic, and was the 8th meteorite analyzed from the 1995-96 collecting season. Below is the technical decription of the meteorite from the February 1998 issue of the Antarctic Meteorite Newsletter.

Sample no:       EET96008
Location:        Elephant Moraine
Dimensions (cm): 4.5 x 3.5 x 1.5
Weight (g):      52.97
Meteorite Type:  Lunar Basaltic Breccia

Macroscopic Description: Kathleen McBride

50% of the meteorite is covered by a black glassy fusion crust. Areas that lack fusion crust appear virtually unweathered. The fusion crust is very thinly distributed over the surface of the rock. The matrix is fine grained, medium gray and tan are are angular and subangular in shape. Metal and rust are not visible. This is a breciated basalt, possibly lunar in origin.

Thin section (,4) Description: Brian Mason

The section shows a microbreccia of pyroxene and plagioclase clasts, up to 1.2 mm across; traces of nickel-iron and sulfide are present, as small scattered grains. Microprobes analyses show that most of the pyroxene ranges from Wo11Fs31 to Wo40Fs18, with a few more iron-rich grains; plagioclase composition in An93-96. A few olivine grains of variable compositions, Fa41-64, were analyzed. Fe/Mn in pyroxene is about 70. The meteorite is a lunar basaltic breccia.

Nakhla To Be Distributed

By Dr. Monica Grady
Natural History Museum, London

Nakhla is a 1300 million year old Martian meteorite, the first one in which carbonates were identified. Nakhla fell as a shower of stones in 1911; several of the stones are in the collection of the Natural History Museum in London.

One completely fusion-crusted stone has been kept unbroken since its acquisition in 1913.

The Natural History Museum is now prepared to offer samples of this stone to scientists for appropriate analyses. The Antarctic Meteorite Processing Group had kindly agreed to allow the stone to be broken and sub-divided at the Curatorial Facility at the Johnson Space Center in Houston, prior to the LPSC in March.

There is no formal deadline for sample requests, but the material available is limited. Coordinated approaches from groups of scientists undertaking complementary studies are encouraged. Those requests submitted to the Museum by April 3 will be processed in April. Those arriving later will be delayed for several months.
