<DIV></DIV>&gt; &gt; A very interesting paper in SCIENCE today. A team of Japanese and American
<DIV></DIV>&gt; &gt; scientists has investigated the basaltic meteorite NWA 011, and discovered that
<DIV></DIV>&gt; &gt; this meteorite resembles an Eucrite but is different in some aspects, most
<DIV></DIV>&gt; &gt; notably the Oxygen Isotope composition. While Eucrite origins are linked with
<DIV></DIV>&gt; &gt; asteroid 4 Vesta, their results suggest that NWA 011 must be from another
<DIV></DIV>&gt; &gt; parent body. Palme, in his News &amp; Views item in the same issue of Science,
<DIV></DIV>&gt; &gt; suggests the option that it is a basalt from the planet Mercury. Below the
<DIV></DIV>&gt; &gt; abstract of the Yamaguchi et al. paper.

<DIV></DIV>&gt;See also:
<DIV></DIV>&gt;
<DIV></DIV>&gt;AFANASIEV S.V. et al. (2000) Dhofar 007 and Northwest Africa 011:
<DIV></DIV>&gt;Two new eucrites of different types (MAPS 35-5, Suppl., 2000, A019):
<DIV></DIV>&gt;
<DIV></DIV>&gt;Here we report data received by studying two new eucrites, Dhofar 007
<DIV></DIV>&gt;from the Oman desert and NWA 011 from the Sahara desert. Based on
<DIV></DIV>&gt;chemical, petrologic, and mineralogical analyses they are classified as
<DIV></DIV>&gt;cumulate (Dhofar 007) and noncumulate (NWA 011).
