Why does gabbro have a higher chemical weathering rate than granite?
Gabbro is mafic intrusive igneous rock and contains olivine, pyroxene, plagioclase and amphibole. These minerals are unstable at low pressure temperature conditions. In contrast, granite is felsic intrusive igneous rock and contains high amounts of quartz and orthoclase. Stability of minerals are increasing top to bottom in Bowen's Reaction Series.
What is olivine syenite?
Extremely iron-rich olivine is rare, but is present in some nepheline syenite. Other minerals common in minor amounts include sodium-rich pyroxene, biotite.
What metals contain steel?
The main element in steel is usually iron. It also contains small amounts of other substances, to improve its properties. Often it contains some carbon (not a metal), and sometimes smaller amounts of other metals.
Which magma contains small amounts of silica and has a low what?
Andesitic
Chargaff showed that DNA contains equal amounts of cytosine and?
guanine

Is turmeric toxic to animals?
not in moderate amounts. it is a powerful detoxifier...
What is the chemical composition of a basalt?
The mineralogy of basalt is characterized by a preponderance of calcic plagioclase feldspar and pyroxene. Olivine can also be a significant constituent.
What type of rock is peridotite?
Peridotite is an ultramafic rock (less than 45% silica) and mainly contains the minerals olivene (a magnesium iron silicate - (Mg,Fe)2SiO4) and pyroxene (XY(Si,Al)2O6 where x may be calcium, sodium, iron or magnesium) and so as can be seen from the chemistry of the two primary minerals contains significant amounts of magnesium and iron.
Compare and contrast granite and diorite?
Contrast: Granite consists mainly of quartz, feldspar, and ferromagnesian ("dark") minerals Diorite may be incorrectly called "granite". Diorite contains virtually no quartz, no muscovite, and no K-feldspar. It also contains a higher percentage of dark silicate minerals. Diorite has a salt and pepper appearance. Compare: Both granite and diorite are phaneritic (course-grained) rocks. Diorite is primarily sodium- rich plagioclase feldspar and amphibole, with lesser amounts of biotite. On other minor constituents of granite include muscovite and some dark silicates, particularly biotite and amphibole.
What is moderate drinking?
Moderate drinking refers to drinking alcohol without drinking excessively. This usually means that a person drinks small amounts on occasion.

What is olivine syenite?
Extremely iron-rich olivine is rare, but is present in some nepheline syenite. Other minerals common in minor amounts include sodium-rich pyroxene, biotite.
What contains large amounts of potassium?
