WebJan 30, 2024 · Streak is not really a meaningful test for a rock, although a weathered basalt is likely to give a brownish streak due to oxidation of its iron-rich minerals. The apparent hardness of a fine-grained rock can also be misleading, because although fresh basalt is indeed quite hard, a weathered piece is likely to be much softer. WebOct 23, 2024 · Chlorite is characterized by the Fe-OH absorption band near 2250 nm (combinations of O-H stretching and Fe-OH bending vibration), whose wavelength position varies as a function of the relative amount of cations in the octahedral sheet [ 24 ].
