Information-rich attributes of minerals reveal their physical, chemical, and biological modes of origin in the context of planetary evolution, and thus they provide the basis for an evolutionary system of mineralogy. Part III of this system considers the formation of 43 different primary crystalline and amorphous phases in chondrules, which are diverse igneous droplets that formed in environments with high dust/gas ratios during an interval of planetesimal accretion and differentiation between 4566 and 4561 Ma. Chondrule mineralogy is complex, with several generations of initial droplet formation via various proposed heating mechanisms, followed in many instances by multiple episodes of reheating and partial melting. Primary chondrule mineralogy thus reflects a dynamic stage of mineral evolution, when the diversity and distribution of natural condensed solids expanded significantly.

矿物学的进化系统。第三部分：原生球粒矿物学（4566 至 4561 Ma）


矿物的信息丰富的属性揭示了它们在行星演化背景下的物理、化学和生物起源模式，从而为矿物学演化系统提供了基础。该系统的第三部分考虑了球粒中 43 种不同的初级结晶相和非晶相的形成，球粒是在 4566 至 4561 Ma 之间的星子吸积和分化期间，在高尘埃/气体比率的环境中形成的不同火成液滴。球粒矿物学很复杂，通过各种提出的加热机制形成了几代初始液滴，在许多情况下随后发生多次再加热和部分熔化。因此，原生球粒矿物学反映了矿物演化的动态阶段，此时天然凝聚固体的多样性和分布显着扩大。
