Analcime
Analcime or analcite (from the Greek analkimos - "weak") is a white, grey, or colourless tectosilicate mineral. Analcime consists of hydrated sodium aluminium silicate in cubic crystalline form. Its chemical formula is NaAlSi2O6·H2O. Minor amounts of potassium and calcium substitute for sodium. A silver-bearing synthetic variety also exists (Ag-analcite).
Analcime is usually classified as a zeolite mineral, but structurally and chemically it is more similar to the feldspathoids. Analcime occurs as a primary mineral in analcime basalt and other alkaline igneous rocks. It also occurs as cavity and vesicle fillings associated with prehnite, calcite, and zeolites.
Locations
Well known locations for sourcing analcime include Croft Quarry in Leicestershire, UK; the Cyclopean Islands east off Sicily and near Trentino in northern Italy; Victoria in Australia; Kerguelen Island in the Indian Ocean; in the Lake Superior copper district of Michigan, Bergen Hill, New Jersey, Golden, Colorado, and at Searles Lake, California in the United States; and at Cape Blomidon, Nova Scotia and Mont Saint-Hilaire, Quebec in Canada; and in Iceland.

Onliest
by: FeistHe sailed the seas to Normandy
He had the maps laid out
He had a boat and had a sail
'Jack's Girl' on his arm
But no one sees the stars so bright
No one swims alone at night
I'm missin' him like a heart attack
And Neptune won't bring him back
refrain:
He watches over me the onliest
He watches over me
He watches over me the onliest
He watches over me
Deepness of the waving tide
All the sea is saying goodbye
And the moon dips aloof at four
The sea doesn't keep score
refrain
Sweetness of the salty wind
Depth of love when it just begins
A pint for me and one for you
Say a toast with all who knew
