June 18, 2017 Weekly Geology Guest

June 17, 2017
Greetings from the Bluff Park Back Porch, way up yonder on Shades Mountain (1,109′) in Alabama:

For the next several weeks, roughly 5 weeks we will discuss the critical metals mentioned in Nova’s Treasures of the Earth.  These include gold, copper, bronze, iron, and steel.

This week we will take a peek at the minerals associated with iron.

IRON
Iron is the cheapest and fourth most abundant metal on Earth.
Iron is a common element in many minerals. The minerals goethite, hematite (ferric oxide), lepidocrocite, magnetite (iron oxide) and siderite (iron carbonate) are all mined for iron. The largest concentrations are in iron-rich sedimentary rocks, and such deposits are mined in Russia, Brazil, China, Australia, India and the USA.

In depth by Wikipedia.

https://en.wikipedia.org/wiki/Iron

The Iron Age is an archaeological era, referring to a period of time in the prehistory and protohistory of the Old World (Afro-Eurasia) when the dominant toolmaking material was iron. It is commonly preceded by the Bronze Age in Europe and Asia and the Stone Age in Africa, with exceptions. Meteoric iron has been used by humans since at least 3200 BC. Ancient iron production did not become widespread until the ability to smelt iron ore, remove impurities and regulate the amount of carbon in the alloy were developed. The start of the Iron Age proper is considered by many to fall between around 1200 BC and 600 BC, depending on the region.

Exceptional Native Wire Silver with Acanthite accenting and Chalcopyrite micro-crystals!
This is by far the finest Wire Silver specimen I’ve seen or offered from this classic German locality. This area of Germany has been mined for Silver since the 15th century. The base of the specimen is a twisting nest of Silver wires, Acanthite and Chalcopyrite. Rising up from this solid foundation are numerous wires of Native Silver ranging from thick to thin. All are firm and quite sturdy – there are no flimsy, wispy wires here! The aesthetics of this specimen are superb and the luster and striations are off the charts. I would rate this as one of my finest German Silvers.

June 11, 2016 Weekly Geology Guess

Greetings from the Bluff Park Back Porch, way up yonder on Shades Mountain (1,109′) in Alabama:

For the next several weeks, roughly 5 weeks we will discuss the critical metals mentioned in Nova’s Treasures of the Earth.  These include gold, copper, bronze, iron, and steel.
This week we will cover bronze, even though it is not a mineral, it is very important in human history.
Bronze is an amalgam of copper and tin.
How mankind figured out how to smelt these 2 minerals, copper and tin, and then combine them to make bronze is amazing to me.

BRONZE
“Bronze is an alloy consisting primarily of copper, commonly with about 12% tin and often with the addition of other metals (such as aluminium, manganese, nickel or zinc) and sometimes non-metals or metalloids such as arsenic, phosphorus or silicon. These additions produce a range of alloys that may be harder than copper alone, or have other useful properties, such as stiffness, ductility, or machinability.”
Cassiterite is a tin oxide mineral, SnO2. It is generally opaque, but it is translucent in thin crystals. Its luster and multiple crystal faces produce a desirable gem. Cassiterite has been the chief tin ore throughout ancient history and remains the most important source of tin today.[2]
Cassiterite Images:

https://images.search.yahoo.com/yhs/search;_ylt=A0LEVr7laT1Zfy0Awj8PxQt.;_ylu=X3oDMTBsa3ZzMnBvBHNlYwNzYwRjb2xvA2JmMQR2dGlkAw–?_adv_prop=image&fr=yhs-lvs-awc&va=cassiterite&hspart=lvs&hsimp=yhs-awc

Since cassiterite is a medium to dark brown mineral and crystal, and that is not that photogenic, except to collectors, I will forgo my usual attached pictures.
But, for additional mental torment examine the following web site on Copper alloys.

June 5. 2017 Weekly Geology Guest, Copper

June 3, 2017
Greetings from the Bluff Park Back Porch, way up yonder on Shades Mountain (1,109′) in Alabama:

For the next several weeks, roughly 5 weeks we will discuss the critical metals mentioned in Nova’s Treasures of the Earth.  These include gold, copper, bronze, iron, and steel.
Copper was one of the first metals to be worked into implements and the first metal to be smelted from ores. Its excellent ductility and high conductivity assure its use in modern society.

Azurite (Carbonate Mineral, Cu3(CO3)2(OH)2

is a soft, deep blue copper mineral produced by weathering of copper ore deposits. It is also known as Chessylite. The blue of azurite is exceptionally deep and clear, and for that reason the mineral has tended to be associated since antiquity with the deep blue color of low-humidity desert and winter skies.

COPPER
Copper was one of the first metals ever extracted and usedby humans, and it has made vital contributions to sustaining
and improving society since the dawn of civilization. Copper was first used in coins and ornaments starting about 8000 B.C.,
and at about 5500 B.C., copper tools helped civilization emerge from the Stone Age. The discovery that copper alloyed with tin
produces bronze marked the beginning of the Bronze Age atabout 3000 B.C.
Copper is easily stretched, molded, and shaped; is resistant to corrosion; and conducts heat and electricity efficiently. As a
result, copper was important to early humans and continues tobe a material of choice for a variety of domestic, industrial, and
high-technology applications today.

Gold
Gold is a chemical element with symbol Au (from Latin: aurum) and atomic number 79. In its purest form, it is a bright, slightly reddish yellow, dense, soft, malleable, and ductile metal. Chemically, gold is a transition metal and a group 11 element. It is one of the least reactive chemical elements and is solid under standard conditions. Gold often occurs in free elemental (native) form, as nuggets or grains, in rocks, in veins, and in alluvial deposits. It occurs in a solid solution series with the native element silver (as electrum) and also naturally alloyed with copper and palladium. Less commonly, it occurs in minerals as gold compounds, often with tellurium (gold tellurides).

Anhydrite Boracite in

Location: ernburg potassic deposits of staßfurt, Saxony-Anhalt, Germany.

Foto: Heart of Gems Gallery

The boracite or parasite is a mineral of the so-called tectoboratos, of class 6 of Borate Minerals. It was named for its high content in the boro. Its Chemical Formula is: mg3b7o13cl
Is the orthorhombic dimorphic (mg3b7o13cl trembathita trigonal). Belonging to the group called “the boracite”, is the equivalent with magnesium (Ericaíta (Fe2+) 3 B7o13cl) and the (Mn3b7o13cl Chambersita). With this latest form the two ends of a series of solid solution, giving a family gradually replacing minerals magnesium for iron.
Even the purest copies usually have some areas with impurities of iron-FE (II) -, which give shades of green.
Can be found in rocks, in the evaporites which is normally associated with plaster, anhydrite and / or halite. Also, though more weird, in marine deposits with potassium.
With the minerals that you usually find associate: Magnesite, kainite, hilgardite, halite, gypsum, carnalite or danburita anhydrite.

Anhydrite is a mineral composed of Calcium Sulfate Anhydrous (Caso4). Comprises 41,2 % of cao and 58,8 % of so3. is very common in the deposits of salt, but it’s very rare to find her well crystallized. When exposed to the action of the water absorbs the anhydrite and transforms into plaster (Caso4• 2 H2o), i.e. hydrated calcium sulphate.
Anhydrite has applications in the construction, in the manufacture of Portland cement, in sulphuric acid and the view of certain fertilizers. The bluish variety called vulpinito vulpine (in Italy) is used as an ornamental stone.
In the salt pans, the origins of anhydrite evaporítico sedimentary. This mineral is deposited from aqueous calcium sulphate with an excess of sodium or potassium chlorate, if the temperature exceeds 40 degrees. In another case, gypsum crystals. This method of formation of anhydrite is one of those who are used to get it artificially. Anhydrite can also form from plaster, for loss of water molecules of the latter.
It’s very common to find anhydrite deposits of salt along with plaster. In fact, the anhydrite was discovered in 1804 in a salt mine in tyrol, Austria. Anhydrite usually occupy the deepest areas of the site, because on the surface the water transforms in plaster.
Sometimes, the anhydrite can be found in threads, associated with calcite, halite, pyrite and sulphites like galena, chalcopyrite and molybdenite.
Anhydrite deposits are scattered throughout the world.
