August 20, 2017 Weekly Geology Guest, Asbestos

August 21, 2017
>    Sorry folks, we have been on vacation from August 11-18, in the Mountains of SW NC, Cashiers, Highlands, Sapphire.  They were gearing up big time =$$$ for the solar eclipse on Monday.
 
 
Greetings from the Bluff Park Back Porch, way up yonder on Shades Mountain (1,109′) in Alabama:
 
 
For the next several weeks we will delve into Industrial Minerals, While they are not glamorous, they are terribly important to our modern way of life. 
 
 

 

Typical examples of industrial rocks and minerals are limestone, clays, sand, gravel, diatomite, kaolin, bentonite, silica, barite, gypsum, and talc. Some examples of applications for industrial minerals are construction, ceramics, paints, electronics, filtration, plastics, glass, detergents and paper.

Asbestos
“Asbestos is a set of six naturally occurring silicate minerals,[1] which all have in common their eponymous asbestiform habit: i.e. long crystals (roughly 1:20 aspect ratio), thin fibrous crystals, with each visible fiber composed of millions of microscopic “fibrils” that can be released by abrasion and other processes.[2] They are commonly known by their colors, as blue asbestos, brown asbestos, white asbestos, and green asbestos.[3]”
“Despite the severity of asbestos-related diseases, the material has extremely widespread use in many areas.  Some of the properties include sound adsorption; resistant to fire, heat and electricity; electrical insulation; building insulation; fire proofing; and vehicle brakes.  Just to name a few.”

Terminal Tourmaline!
 
“Tourmaline ( /ˈtʊərməln/ TOOR-mə-leen) is a crystalline boron silicate mineral compounded with elements such as aluminium, iron, magnesium, sodium, lithium, or potassium. Tourmaline is classified as a semi-precious stone and the gemstone comes in a wide variety of colors.
 
Lepidolite is a lilac-gray or rose-colored member of the mica group of minerals with formula K(Li,Al,Rb)2(Al,Si)4O10(F,OH)2.[1][2] It is the most abundant lithium-bearing mineral
Albite is a plagioclase feldspar mineral. It is the sodium endmember of the plagioclase solid solution series.  Its color is usually pure white.
Orthoclase, or orthoclase feldspar (endmember formula KAlSi3O8), is an important tectosilicate mineral which forms igneous rock.”

July 30, Weekly Geology Guest, Industrial Minerals

Greetings from the Bluff Park Back Porch, way up yonder on Shades Mountain (1,109′) in Alabama:
 
 
For the next several weeks we will delve into Industrial Minerals, While they are not glamorous, they are terribly important to our modern way of life.
 

Industrial resources (minerals) are geological materials which are mined for their commercial value, which are not fuel (fuel minerals or mineral fuels) and are not sources of metals (metallic minerals) but are used in the industries based on their physical and/or chemical properties.[1] They are used in their natural state or after beneficiation either as raw materials or as additives in a wide range of applications.

Typical examples of industrial rocks and minerals are limestone, clays, sand, gravel, diatomite, kaolin, bentonite, silica, barite, gypsum, and talc. Some examples of applications for industrial minerals are construction, ceramics, paints, electronics, filtration, plastics, glass, detergents and paper.

What is an Industrial Mineral?
An industrial mineral is any naturally-occurring rock or mineral of economic value, exclusive of metallic ores, mineral fuels, and gem stones.   Industrial minerals may be located in igneous, metamorphic and sedimentary rocks (Bates and Jackson, 1984).
Industrial minerals that form from igneous processes include many pegmatite minerals, such as  muscovite, feldspars, spodumene, tourmaline, and beryl, as well as the igneous rocks themselves.  The latter, including granite, diorite, and gabbro, may be valued for their durability and beauty. 
Industrial minerals that are formed as a result of metamorphism include the rocks slate and marble, as well as minerals asbestos, wollastonite, garnet, and talc.
Industrial minerals occur in marine sedimentary rocks (limestone, dolomite, salt, gypsum) and non-marine sedimentary rocks (sand & gravel in stream deposits).
 
Classifications of Industrial Minerals:
Industrial minerals can be subdivided into two basic groups based on uses:
Fertilizer and Chemical Minerals:
bullet These are minerals essential for growing food (mostly potassium, nitrogen, phosphorus) and in many chemical applications (e.g. salt, sulfur, boron, soda ash).
Construction and Manufacturing Minerals:
bullet These are minerals and rocks that are used extensively in our infrastructure,  mostly in roads and buildings.

Cobaltoan Calcite: A variety of Calcite containing Co2+ From Morocco

Good Morning, Friends…

Here we have PENTAGONITE, a rare hydrous vanadium silicate mineral with the chemical formula Ca(VO)Si4O10·4(H2O)

The term “Penta” comes from Ancient Greek and refers to “five”… having five or containing five…

Penta’s name association to this pretty mineral is due to its crystal twinning * which has a FIVE-fold symmetry / habit.

* Crystal twinning is the result of two separate crystals sharing
some of the same crystal lattice points in a symmetrical manner.
This results in an inter-growth of two separate crystals in a number of different forms.

Who noticed that the blue in pentagonite is very similar to that of cavansite? There is good reason for this.

They are POLYMORPHS of each other (same chemical composition, different crystal structure). The primary difference lies within the arrangement of the layers of silicate.

Cavansite forms as prismatic (resembling a prism) crystals, often as radiating clusters.

Interesting to note that both of these gorgeous blue minerals come from around the same area: Poona (aka Pune), India.

From the Wagholi Quarries (Pune District) of Maharashtra, India :
