Bowens' Reaction Series measures the melting points of various silicate minerals, with the ones with highest melting points at the top. So as a completely molten
magma containing all these minerals cools down, the first to crystallise are:
ABOUT 1400 CELSIUS
ABOUT 800 CELSIUS
Notice I've deliberately left out plagioclase feldspar because plagioclases of different composition crystallise out at different temperatures. Calcium-rich plagioclase crystallises out at about the same temperature as olivine (mineral 1), but sodium-rich plagioclase crystallises out about the same temperature as biotite mica (mineral 4). All plagioclase crystallises out at a higher temperature than orthoclase (mineral 5).
So in answer to your question the first minerals to form as a magma cools are olivine and calcium-rich plagioclase feldspar, at around 1400 Celsius.
There is no exact formula. To find the sequence of LCMs see http://oeis.org/A003418/list. LCM(1, 2, 3, ..., n) tends to en as n tends to infinity. Equivalently, ln[LCM(1, 2, 3, ..., n)] tends to n or ln[LCM(1, 2, 3, ..., n)] / n tends to 1 as n tends to infinity.
Due to the length of the book, the Harry Potter and the Philosopher's Stone movie is generally considered the most faithful adaption in the series. It is also the most popular as people will watch the first movie before deciding to continue watching the second.The final movie, Harry Potter and the Deathly Hallows Part 2, made the most money at box office. A fan favourite tends to be the third film, Harry Potter and the Prisoner of Azkaban.
No, he says in his autobiography that he tends to side with Republicans.
Just over one (1) year is the expected lifespan of an Irish robin (Erithacus rubecula melophilus).Specifically, the first year of existence is the most dangerous for a robin. If a robin can survive that first perilous year, then the lifespan may range from a couple to 10+ years of existence. It depends upon the numbers and agility of predators in the parks and gardens that the Irish robin tends to call home.
A Scorpio - Aquarius relationship tends to be difficult.
Olivine
No. If x tends to infinite, 1/x tends to zero.
I think that is A Series of Unfortunate Events, which book in that series is hard to say, most likely the first one because that tends to be the one people read first and decide if they wish to read on.
Quartz.
No. For fossil formation to take place a series of fortunate events must occur. If any part of the series is missing we will never see the fossil! In fact, fossilization is a fairly rare occurrence. Nature tends toward recycling. That includes just about everything from plants and animals to rocks and minerals.
Atmospheric oxygen tends to be elemental oxygen (O2). Oxygen in rocks and minerals is chemically combined with other elements to form compounds called oxides.

Plains receive eroded minerals from higher elevations, and erosion does not remove as much dead plant material as it does from hills and mountains. Precipitation tends to percolate minerals down into the soil.
An arithmetic series is the sequence of partial sums of an arithmetic sequence. That is, if A = {a, a+d, a+2d, ..., a+(n-1)d, ... } then the terms of the arithmetic series, S(n), are the sums of the first n terms and S(n) = n/2*[2a + (n-1)d]. Arithmetic series can never converge.A geometric series is the sequence of partial sums of a geometric sequence. That is, if G = {a, ar, ar^2, ..., ar^(n-1), ... } then the terms of the geometric series, T(n), are the sums of the first n terms and T(n) = a*(1 - r^n)/(1 - r). If |r| < 1 then T(n) tends to 1/(1 - r) as n tends to infinity.
This series of random letters tends to denote boredom, awkwardness, or lack of something to say on the Internet.
"It is best to demagnetize metal objects before using them around magnetic tape drives." "Heat tends to demagnetize ferrous minerals."
The Everyman Library series covers a wide range of fiction genres, but one genre that is not typically represented in the series is science fiction. The series tends to focus more on classic literature, history, philosophy, and poetry.
