Growth histories and residence times of crystals in magmatic systems can be revealed by studying crystal sizes, size distributions and shapes. In this contribution, serial sectioning has been employed on a sample of porphyritic rhyolite from a Permo-Carboniferous laccolith from the Halle Volcanic Complex, Germany, to reconstruct the distribution of felsic phenocrysts in three dimensions in orde...

Karapınar-Karacadağ Volcanic Rocks (KKVR) have very complex magmatic history and outcropped the southwestern part of Cappadocia Province (Central Anatolia). Here we present petrography whole-rock chemistry enclave-bearing rocks to constrain their source evolution history. These petrographic observation geochemical data reveal that enclaves in volcanic are magma mixing/mingling (MME), segregatio...

The Upper Cretaceous Sannae-Eonyang granite crystallized approximately 73 Ma and hosted the Sannae W-Mo deposit in west Eonyang amethyst east. contained textural zones of miarolitic cavities unidirectional solidification texture (UST) quartz. UST rock sampled mine consisted (1) early cavity-bearing aplitic granite, (2) co-crystallization feldspars quartz a granophyric (3) latest growth larger c...

Chondrule textures depend on the extent of melting of the chondrule precursor material when cooling starts. If viable nuclei remain in the melt, crystallization begins immediately, producing crystals with shapes that approach equilibrium. If not, crystallization does not occur until the melt is supersaturated, resulting in more rapid growth rates and the formation of skeletal or dendritic cryst...

Introduction: Chondrules are free from trapped noble gases [e.g., 1], which is attributed to complete degassing during the chondrule formation. However, Okazaki et al. [2] discovered the Ar-rich trapped noble gases in enstatite chondrite chondrules. The Ar-rich gases were formed via incomplete degassing (He and Ne depletion) of implanted solar gases during the chondrule formation [2]. Since sol...
