Essexite
Essexite (/ˈɛsəkˌsaɪt/), also called nepheline monzogabbro (/ˈnɛfəˌlɪn ˌmɒnzoʊˈɡæbroʊ, -ˌliːn-/), is a dark gray or black holocrystalline plutonic igneous rock. Its name is derived from the type locality in Essex County, Massachusetts, in the United States.
Modern petrology identifies rocks according to mineralogical criteria. Utilising the IUGS QAPF diagram of Streckeisen (1974) "essexite" is more formally known as nepheline monzodiorite or nepheline monzogabbro depending on the ratio of orthoclase to plagioclase and the abundance of nepheline.
Petrology
In order to produce a magma composition suitable for forming essexite the partial melting of the source rocks must be restricted, generally to less than 10% partial melting.
This favors producing a melt rich in large-ion lithophile elements (LILE) such as K, Ba, Rb, Cs, Sr.
The source melts of essexites contain more aluminium and alkali ions than available silica tetrahedra, which is why essexites crystallise nepheline instead of plagicolase. Higher than normal potassium favors the production of orthoclase, which is usually absent from most mafic igneous rocks.

Lights Out
by: Jessica SuttaI can see you
But I know you by your touch, your touch, your touch
I can hear you but the music is enough, enough, enough
To know what’s happening tonight
So I’mma put my hands higher and higher
We made through the day alive
So I’mma put my hands higher and higher
I want your love to set me free
Baby, be the only one that I’ll ever need
A shooting star for you to see
So keep the lights low
When you’re next to me
Oh Oh Oh Oh Oh Oh Oh
Let tonight take over now
‘Cause I can feel u better
When the light’s out
Turn the lights out
‘Cause I can feel u better
When the light’s out – (turn the lights out)
‘Cause I can feel u better
When the light’s out
When I’m near you
I can always feel the rush, the rush, the rush
I’ll never leave you
Cause your eyes say enough, enough, enough
