Porphryryyog pob zeb demicious los ntawm ib qho txawvporphyritic kev ntxhib los mos, txhais tau tias nws muaj cov muaju loj, ua kom zoo (phenocrysts)Ob-theem cua txias:
- Qeeb Cua Txias Ntawm Qhov tob→ txhawb nqa txoj kev loj hlob ntawm phenocrysts loj (e .}}}, fphibole) .
- Sai sai txias rau kev siv pob zeb lossis ntiavZoo-grained lossis iav matrix solidfies ncig lub phenocrysts .
Cov yam ntxwv tseem ceeb ntawm porphyry:
Muaj pes tsawg: Feem ntau intermediation rau felsic (e . g .,Granite porphyry, Rhyolite porphyry) Tab sis kuj tseem tuaj yeem ua mafic (e {. g .,Basalt Porphyry).
Qhov ntau thiab tsawg: me, xws li 10x10CM, 10 x 15CMM, 20x20c, 30x30cm, max 30x60cm .
Xaus:honed, polished (tsis yog ci ncauj), bush rauj

Kev tshawb fawb paub tseeb:
Kev nyeem ntawv: Porphyriticic (phahaneric lossis aphanitic matrix) .
Yam muaj: Subvolcanic (hypabyssal) sterusions lossis cov pob zeb elcanic sib xyaw .
Qhov no dual-theem crystallization ua porphyry tseem ceeb rau kev nkag siab cov txheej txheem Magmatic thiab ONe Chiv Keeb.
