Gold Rates Increasing Day By Day

Gold has had an inestimable effect on human history. It has been crafted,

mined, worshipped, plundered, fought over and traded for thousands of years.

Today, the search for gold is as eager as ever, despite the vast stocks stored

away in underground bunkers. So why has gold held this fascination for

humanity?

A popular misconception is that natural gold has cooled from a molten state.

In fact, gold is transported though the Earth’s crust dissolved in warm to hot

salty water. These fluids are generated in huge volumes deep in the Earth’s

crust as water-bearing minerals dehydrate during metamorphism. Any gold

present in the rocks being heated and squeezed is sweated out and goes into

solution as complex ions. In this form, dissolved gold, along with other

elements such as silicon, iron and sulphur, migrates wherever fractures in the

rocks allow the fluids to pass. This direction is generally upwards, to cooler

regions at lower pressures nearer the Earth’s surface. Under these conditions,

the gold eventually becomes insoluble and begins to crystallise, most often

enveloped by masses of white silicon dioxide, known as quartz. This

association of gold and quartz forms one of the most common types of "primary

gold deposits".

Gold occasionally takes forms that lend themselves to descriptive terms such

as wire gold, nail gold, mustard gold and paint gold. While all gold has a

crystalline structure, distinct crystals showing well-formed faces are

relatively rare. They require special conditions to form, in particular space

in which to grow. Hence crystals of gold are found in cavities in quartz reefs

or in softer minerals such as iron oxides where they have been able to push

aside the enclosing material as they grew. Gold crystallises in the cubic

system, and perhaps the most common variety is the eight-sided octahedron.

Its initial attraction is its color, an eye-catching and characteristic bright

yellow with a soft metallic glint. Gold’s pleasant ‘feel’, a combination of

its density (19.3 grams per cubic centimetre when pure) and coldness, cannot

be duplicated by any other metal. Furthermore, gold can be hammered into very

thin sheets or leaves, drawn into wire, cast, carved, polished, heated without

tarnishing and easily combined (alloyed) with other metals.
