Vitrophyre
A vitrophyre is a porphyritic volcanic rock in which phenocrysts are embedded in a glassy matrix. Vitrophyres are contrasted from typical porphyritic rocks in that the latter has both crystalline phenocrysts (larger grains) and a crystalline matrix wikipedia.org

Halleflinta
Many examples are banded or striated; others contain porphyritic crystals of quartz which resemble those of the felsites and porphyries. Of its original nature there is some doubt, but its chemical composition and the occasional presence of porphyritic crystals indicate that it has affinities wikipedia.org

斑状
斑状（Porphyritic）是地质学中使用的形容词，尤其是指火成岩中晶体大小有明显差异的岩石，至少其中一组晶体明显大于其它晶体。斑状岩石可能是隐晶岩或喷出岩，大型晶体或斑晶漂浮在不可见晶体的细粒基质中，如斑状玄武岩、或闪长岩或侵入岩中。 wikipedia.org

Llanite
Llanite is a porphyritic rhyolite with distinctive phenocrysts of blue quartz (a rare quartz color) and perthitic feldspar (light grayish-orangeish). Llanite comes from a hypabyssal porphyritic rhyolite dike that intrudes Precambrian metamorphics in the Llano Uplift of central Texas. wikipedia.org

Chondrule
More commonly, chondrules display what is known as a porphyritic texture. They are named on the basis of the dominant mineral, i.e. porphyritic olivine (PO), porphyritic pyroxene (PP), and porphyritic olivine-pyroxene (POP). wikipedia.org

Latite
Latite is an igneous, volcanic rock, with aphanitic-aphyric to aphyric-porphyritic texture. Rhomb porphyries are an unusual variety with gray-white porphyritic rhomb shaped phenocrysts embedded in a very fine grained red-brown matrix. wikipedia.org

Igneous textures
The six main types of textures are phaneritic, aphanitic, porphyritic, glassy, pyroclastic, and pegmatitic. Porphyritic textures develop when conditions during the cooling of magma change relatively quickly. wikipedia.org
