How is quartz a fracture?
No, you would not, for the same reason I posted in your other question. The temperature for olivine to appear is a lot higher than the temperature for quartz. If you look at the figure I posted in the other question, you can see that quartz and olivine are never in the same area. I'll post the figure again for quickness: www-personal.umich.edu/~jmpares/i...
Many diamonds have inner lines of olivine trapped interior them for the main area , counting on the advent element and the encircling enviorment i could think of something is conceivable.Quartz is often present day in igneous for the main area in basically 2 different stages , one straight away from the magma or hydro thermally after cooling.i think of the respond on your question could be pegmatitic.
