Green feldspar is always K-feldspar, a variety called amazonite. Field workers generally just write down "K-spar" and leave it at that until they can get to the laboratory. Igneous rocks in which the feldspar is all or mostly alkali feldspar are called syenite (if quartz is rare or absent), quartz syenite or syenogranite (if quartz is abundant).

The Density of Common Rocks and Minerals - ThoughtCo

Jan 23, 2020 · 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.

Sep 26, 2018 · Magnetic mineral inclusions in silicates are widespread in sediments as well as in igneous rocks. Because they are isolated from surrounding environment, they have potential to preserve original magnetic signature even in chemically altered sediments. Such inclusions may provide proxies to help differentiating the source of the host silicate. We measure magnetism of quartz and feldspars .

Comments: Syenite is a coarse-grained, intrusive igneous rock that is composed largely of sodium- or potassium-rich feldspar and of a ferromagnesian mineral. The feldspar commonly is orthoclase, albite, perthite, or, more rarely, microcline, and the dark-colored ferromagnesian mineral usually is biotite mica, hornblende, or a pyroxene; some .
