The coarse lamellae that are visible in the meteorite hand samples is kamacite. In most of the samples the taenite lamellae are too time to be seen with the naked eye. Classification of iron meteorites is based largely on the nature of the kamacite exsolution lamellae Look carefully at each of these samples of Fe meteorites and rank the samples in terms of relative cooling rate of the parent bodies. Examine the 2 samples of stony-iron meteorites. Chondritic meteorites are distinguished from all other types of rocks by the presence of chondrules, small spherical silicate masses.
Most chondrites contain a variety of different types of chondrules.
The chondrules sit in a matrix of silicates with minor amounts of metal. Describe textures that are found in both the terrestrial samples and the meteorite. Describe textures found only in the meteorite. Describe 3 different types of chondrules. Look at the chondrules and matrix of the following meteorite samples.
