What are the features of two major groups of minerals?
silicate minerals and non silicate minerals
In bowens reaction series how do the tetrahedra in feldspar differ from those of silicates?
The simple answer is... Feldspar has a much higher complex and stable tetrahedral orientation in comparison to that of any other Silicate variation higher up on the reation series latter. Feldspar is one of the most stable variations in orientation of, what boils down to, silicate tetrahedra. Because Feldspar is technically a form of silicate tetrahedra orientation, I am assuming you are asking how the silicate tetrahedra orientations vary from its most simple (i.e. Olivine) to its mosts complex (i.e. quartz/FELDSPAR) forms. Esentially a Silicate Ion SiO4^-4 is the most basic building block of FELDSPAR. Knowing this, as you move from the top of Bowen's reaction series, we see a gradual stabilization of the various Silicate tetrahedral orientations. These orientations include (in order of stability/complexity): [TOP OF REACTION SERIES] Individual (Singular form) Silicate Tetrahedra (i.e. Olivine) Chain (Linear form) Silicate Tetrahedra (i.e. Pyroxine) Double Chain (Bilinear form) Silicate Tetrahedra (i.e. amphibole) Sheet Silicate Tetrahedra ('2-D' form) (i.e. Mica: Biotite or Muscovite) Framework Silicate Tetrahedra ('3-D' form) (i.e. FELDSPAR) [BOTTOM OF REACTION SERIES]
What is the formula for manganese(iv) silicate?

Is a stalagmight up?
A stalagmite is a build up of silicate on the base of a cave, many times in the shape of a cone with the base on the floor of the cave, as it extends to the ceiling.
What type of rock is limonite?
Limonite is a mineral, a component of rock.
What color is limonite?
Limonite is a natural iron ore. Limonite can be found in various shades of brown, yellow, orange and combinations of the three.
Where is limonite found?
Limonite is found in many places including geothermal hotpots.
Does limonite have cleavage or fracture?
Limonite is a mixture of other minerals it has no clevage of it's own.
Is limonite in paint?
no
What are some of important uses for limonite?
Limonite can be used as a pigment in paint and has some medical purpose
What is LIMONITE used for?
limonite is used for changing the color of paint from red to yellow. and made in white paint
What are uses of limonite?
limonite is a minor ore of iron, it is used in Chinese in medicine and it is used in white paint.
What is the chemical make-up of limonite?
Limonite is an iron ore; the approximative composition is FeO(OH).nH2O.
Does limonite have fracture?
yes it does
What is the hardness of Limonite on the mohs hardness scale?
The hardness of Limonite is 4 t0 5.5 on the mohs hardness scale.
How can the streak test be used to identify limonite and hematite?
Hematite has a red streak. It can vary in depth of color, depending on the variety of hematite. Limonite has a yellow-brown (more brown than yellow) streak. But you have to make sure you are streaking the limonite and not an underlying mineral, if the limonite is located on another mineral.
