when a diorite partially melts, which element(1)............ decreases in the melt as a(2).......... magma forms.
I have few options to choose from
a)iron
b)andesite
c)rhyolite
d)potassium
f)basalt
No one has
Icma Question read the book then read the question again its in the question
stop bloody cheating and do some hard work like the rest of us!!
Above can hardly talk about cheating, in order for you to have found this page you had to search the question, thus you were trying to cheat also.
Before you start pointing fingers, make sure your hands are clean.
Last answer about finger pointing has hilarious. I was also here to cheat too.
*Jumping hiegh feives!!* ;)
To determine which element decreases in the melt as diorite partially melts, we need to understand the composition of diorite and how it melts to form magma.
Diorite is a common intrusive igneous rock composed mainly of plagioclase feldspar, biotite, amphibole, and a small amount of quartz or other minerals. When diorite undergoes partial melting, only certain minerals will melt, while others remain solid.
In this case, the key element to consider is potassium (K). Potassium is an important component of potassium feldspar, one of the minerals present in diorite. When diorite partially melts to form magma, the melting process preferentially melts minerals low in potassium. Therefore, the amount of potassium decreases in the melt as magma forms.
From the given options, the correct answer is (d) potassium.
