Porphyry (geology)

Porphyry is a textural term for an igneous rock consisting of large-grained crystals such as feldspar or quartz dispersed in a fine-grained silicate rich generally aphanitic matrix or groundmass The larger crystals are called phenocrysts In its non-geologic traditional use the term porphyry refers to the purple-red form of this stone valued for its appearance

The Density of Common Rocks and Minerals

Rock density is very sensitive to the minerals that compose a particular rock type Sedimentary rocks (and granite) which are rich in quartz and feldspar tend to be less dense than volcanic rocks And if you know your igneous petrology you will see that the more mafic (rich in magnesium and iron) a rock is the greater its density
