Relating to the early stage of rock formation where primary minerals are crystallizing directly from molten material.
From Greek 'blastos' (germ/primordial) + '-phytic' (relating to growth or formation). Used in geology and mineralogy to describe primary crystallization textures.
Blastophitic textures in rocks preserve the fingerprints of how magma cooled—geologists can read these crystal patterns like a diary of Earth's interior conditions.
