Ironstone

Ironstone is a sedimentary rock, either deposited directly as a ferruginous sediment or created by chemical replacement, that contains a substantial proportion of an iron compound from which iron either can be or once was smelted commercially. This term is customarily restricted to hard coarsely banded, nonbanded, and noncherty sedimentary rocks of post-Precambrian age. The Precambrian deposits, which have a different origin, are generally known as banded iron formations. The iron minerals comprising ironstones can consist either of oxides, i.e. limonite, hematite, and magnetite; carbonates, i.e. siderite; silicates, i.e. chamosite; or some combination of these minerals.

Description

Freshly cleaved ironstone is usually grey. The brown external appearance is due to oxidation of its surface. Ironstone, being a sedimentary rock is not always homogeneous, and can be found in a red and black banded form called tiger iron, sometimes used for jewelry purposes.

Sometimes ironstone hosts concretions or opal gems.

Ernestine

by: Desir Noir

There is no difference between death
and life
Just a circle to be closed by time
Creature comforts in this earthly plane
Have become more hallowed than
wisdom today
In the stream of consciousness
We cannot see the truth
Play your role so perfectly
No matter which life we choose
Emotional terror confusing our minds
Love and hate keeping us blind
Pretend death is the end of the line
Expect rewards in paradise
In the stream of consciousness
We cannot see the truth
Play your role so perfectly
No matter which way we choose
Living in an ice age, emotions gone numb
The truth once so near but now so
far away
So turn another page, get our daily
work done
All the nightmares are clear and
happening today
Mindless fools, obey all rules
Lost all worth, born to serve
Emotional terror confusing our minds
Hate and love is keeping us blind
Creature comforts in this earthly plane
Have become more hallowed than
wisdom today
There is no difference between death
and life
Just a circle to be closed by time
Pretend death is the end of the line
Expect reward in paradise
In the stream of consciousness
We cannot see the truth
Play your role so perfectly
No matter which life we choose
