Meteorito Barea, Varea, Logroño, La Rioja, España


Mesosiderite, A-1
Fall, 4 July 1841, 3.2 kg

The Barea stone fell near Logroño, Spain. With a volume more than 50% silicate and a mass more than 50% Fe-Ni metal [plus ~1-2% other phases], it was quickly recognized as a stony-iron and, in time, classified as a part of the Mesosiderite class. Mesosiderites are complex mixtures of one or more particularly violent and ancient impacts which may have involved either a metal-rich projectile or the deep penetration by an impactor into the upper core of an ancient asteroid. In any case, Barea was the first of only 7 witnessed mesosiderite falls (~ .5% of all falls). Over a century after its fall, portions of the meteorite were carefully observed by several masters of the mineralogical trade (Mason, Ramdohr, and others) and its major, minor, and several trace constituents have been both identified and studied. The predominant silicate is pyroxene (Fs30) ('hypersthene' in the meteoritic literature), but minor and frequently variable plagioclase (Ca-rich) and olivine (Fo68-80) as well as tridymite are observed. Metal is mostly kamacite, but taenite is present. Other minor phases usually found in mesosiderites — troilite, ilmenite, and merrillite — are also present. Very small amounts of copper, graphite, schreibersite, and rutile are reported. Barea's petrologic type 1 designation indicates that its brecciated components have been mildly recrystallized since their original fragmentation.

Inconclusive attempts to determine the cosmic ray exposure age are reported in the literature. Difficulties appear to be rooted in accounting for the different shielding factors of the metal and silicates. The main mass (1.7 kg) is held in Spain's National Science Museum in Madrid.
