What is a granodiorite stele?
Granodiorite is most often used as crushed stone for road building. It is also used as construction material, building facade, and paving, and as an ornamental stone. The Rosetta Stone is a stele made from granodiorite.
Is granodiorite a granitoid?
A granitoid is a coarse grained igneous rock composed mostly of quartz, K-feldspar (alkali-feldspar) and plagioclase), with 20-60% quartz on the QAPF diagram. It usually contains minor micas and/or amphiboles. Most commonly granite and granodiorite.
Where is granodiorite found in Nigeria?
Zuma Rock is a large natural monolith, or inselberg, an igneous intrusion composed of gabbro and granodiorite, in Niger State, Nigeria. It is located immediately west of Nigeria’s capital Abuja, along the main road from Abuja to Kaduna off Madala, and is sometimes referred to as the “Gateway to Abuja from Suleja”.
What is the difference between granite and granodiorite Google it !)?
What is the difference between granite and granodiorite? These rocks are both classified as granitic, because they both are rich in quartz. In contrast, granodiorite contains more plagioclase (calcium and sodium) feldspar than potassium feldspar and has more dark minerals. Thus it is a darker color than granite.
What is the difference between diorite and granodiorite?
is that granodiorite is (rock) an intrusive igneous rock similar to granite, but containing more plagioclase than potassium feldspar while diorite is (rock) a grey intrusive igneous rock composed mostly of plagioclase feldspar, biotite, hornblende and/or pyroxene.
Where can granodiorite be found?
An intrusive igneous rock, granodiorite often forms large masses in the roots of mountain ranges, such as the Andes. It also often occurs in association with granitic batholiths. Indeed, granodiorite is often confused with granite, a rock with which it shares a similar appearance, texture, and composition.
Does granodiorite contain gold?
In Federal open pit, the granodiorite is coarse-grained in the northern half, and a fine-grained granodiorite in the south, with both hosting gold. These two types of granodiorite are rather similar in both mineralogy and geochemistry. There is also a subordinate fine- grained monzodiorite.
Why is Zuma Rock famous?
Zuma Rock is historically served as the protection fort for the Gbagyi people during intertribal wars. Zuma Rock is often described by many as the Gateway to Abuja from Suleja. The first settlers around the rock back in the 15th century were the Zuba and Koro people.
Which rock is the highest in Nigeria?

Is granodiorite a volcanic?
It is commonly produced in volcanic arcs, and in mountain building where it emplaces as large batholiths in mountain roots. Granodiorite is the plutonic equivalent of dacite.
