Chondrules are millimetre-sized spherules (mostly silicate) that dominate the texture of primitive meteorites. Their formation mechanism is debated, but their sheer abundance suggests that the mechanism was both energetic and ubiquitous in the early inner Solar System. The processes suggested—such as shock waves, solar flares or nebula lightning—operate on different length scales that have been hard to relate directly to chondrule properties. Chondrules are depleted in volatile elements, but… CONTINUE READING
