carbonaceous chondrite,thermal metamorphism,amorphous silicate,in-situ observation

In this study, we performed in-situ TEM experiments on the thermal metamorphism of amorphous silicate matrix in primitive carbonaceous chondrite. We will present the results showing thermal evolution of the amorphous silicates including dehydration of the amorphous silicates and formation of nano silicate crystals.
