Porphyry is a neutral, acidic, or alkaline igneous rock that has a patchy structure (which can be intrusive or jet-rock). They are usually scattered in a small crystalline mineral called a "matrix" usually referred to as the alkaline feldspar as the plaque, the matrix is a fine or hidden crystal of the injection of rock and supergene. Porphyry is a plaque-like structure of igneous rock, relatively strong, can be used to make building materials. Usually made of alkaline feldspar or quartz, the substrate is a fine or hidden crystal (vitreous)

Generally refers to the alkaline feldspar or quartz for the porphyry and Supergene, the matrix is fine grain or hidden crystal-glass. The spouting rock can be divided into the flow pattern porphyry, the coarse surface porphyry, the white eclogite and so on, the supergene can be divided into quartz porphyry, granite porphyry, and the long porphyry.

The term "porphyry" refers to igneous rocks with plaque or plaque structure, which can be described as granitic porphyry and flash-long porphyry in terms of matrix composition. Porphyry and Porphyrite Rocks are the products of two stages of magmatic crystallization, and the crystals formed in the deeper part of the magma at the early stage of magmatic, and the matrix is the product of the shallow crust crystallization in late stage. There are copper, molybdenum, tungsten, iron and other mineral deposits which have the Genesis relationship with Porphyry and porphyrite rocks. Porphyry and porphyrite Rocks are distinguished only in China, and there is no distinction in foreign countries.

Porphyry is mainly divided into two major types of supergene, spouting rock is the volcanic magma after the condensation formed, due to the rapid cooling after the injection, forming many fine particles; supergene is formed by volcanic magma invading the shallow crust (typically 1.5-3-kilometer), and there are many crystalline plaques.
