All combinations of possible symmetry elements (and some single elements) are referred to six crystal systems. which are these six?

There are a total six crystal system like triclinic, monoclinic, tetragonal, hexagonal, orthorhombic and cubic.

Explanation:

The crystal forms of the crystal family refer to several classes of crystals that are informally formed by the grouping of crystal and being divided based on sources. The crystal; system that corresponds to space groups is given a lattice system giving them a 32 point scale. These points are assigned to the trigonal crystal system which consists of all the above 6 system forms of crystals. Their name is given by Whittaker who formed these crystal structures as protein structures

Magma forms by partial melting of upper mantle and crust. partial melt means that only a fraction of the available material forms a melt, and that the remainder stays solid. the partial melt rises because of its lower density and ascends through he crust. this is so conclusive mean the answer would be magma igneous rocks or balistic magma.
