For geology we have to compare and contrast quartz and halite for an essay conceptual question. Another part pf the question is to compare and contrast graphite and diamond. I have figured out that part, but this part is driving me crazy! Ive been researching to forever... Help please!
can't remember how itz formed, but here is an interesting fact... the only thing that causes quartz to deteriorate is animal fluids as in dead animal fluids.
Quartz is usually formed at the final stages of an igneous melt, where any excess silica (SiO2) crystallizes and form quartz. Quartz is probably the most common mineral in the crust of the Earth, and it is unusal in that it has a three dimensional structure by lacks cleavage, and has a concoidal fracture. It is a hard mineral with a Mohs Hardness of 7. This hardness and lack of cleavage means that quartz resists breakdown and forms into sands along beaches.
