Llanite, which is similar to granite, is very strong, with a crushing strength of 37,800 lb/in 2 or 26,577,180 kg/m 2. [4] The mineral is also very similar in appearance to pietersite. [citation needed] Modal mineralogy of llanite: [5] quartz – 34.6%; microcline – 27.8%; plagioclase – 27.9%; biotite – 8.6%; fluorite – 1.1%; apatite ...
The S-type Strathbogie Granite crops out in the Strathbogie Ranges of Australia. A hand sample from the Strathbogie Granite has a porphyritic texture with larger crystal of grey quartz, called phenocrysts, set in a finer grain matrix of quartz and feldspar.

Monzonite is defined as rock having less than 5% quartz in its QAPF fraction and in which alkali feldspar makes up between 35% and 65% of the total feldspar content. If quartz constitutes greater than 5% of the QAPF fraction, the rock is termed a quartz monzonite , while if feldspathoids are present as up to 10% of the QAPF fraction, the rock ...
The relative abundances of quartz (Q), alkali feldspar (A), plagioclase (P), and feldspathoid (F), are used to plot the position of the rock on the diagram. [ 5 ] [ 6 ] [ 7 ] The rock will be classified as either a dioritoid or a gabbroid if quartz makes up less than 20% of the QAPF content, feldspathoid makes up less than 10% of the QAPF ...
Carrara marble has been used since the time of Ancient Rome, when it was called marmor lunense, or "Luni marble". [2] [3]In the Middle Ages, most of the quarries were owned by the Marquis Malaspina who in turn rented them to families of Carrara masters who managed both the extraction and transport of the precious material.
