It is a split in the earth crust where the two sides may shift in
opposing directions, resulting in an earthquake.
Any mineral belonging to the feldspar group.
It is group of minerals of aluminum silicates which contains potassium,
sodium, and/or calcium. This group of minerals is abundant on earth.
Any mineral belonging to the feldspathoid group.
It is the group of minerals which are similar to feldspars. It lacks in
the amount of silica to fully make them into feldspars while forming. As
feldspars, they are aluminum silicates of potassium, sodium, and/or
calcium. It is in the tectosilicates subdivision of the silicates group.
It describes the rock-forming silicate minerals that contain essential
iron (Fe) and/or magnesium (Mg). The very common ferromagnesian minerals
include olivine, pyroxene, amphibole and mica.
It is a term for greatly attracted to magnetic fields.
It is referred to the magnetic property in certain materials which
causes them to get attracted to magnetic fields.
It is an aggregate which describes to a mineral constructed of fine and
parallel (usually) threads. Some of the fibrous minerals can be bent
around easily because of the cloth-like flexibility.
It is test that is conducted to identify a mineral. It is a complex
process. A tiny fragment of a mineral is placed at one end of a platinum
wire and held in a flame. The change of the flame changes due to the
presence of different metals like sodium will give yellow flame; copper,
blue and green; potassium, violet; etc.
Minerals which are capable of getting bent without breaking are said
such. Flexibility is a form of tenacity.
It is a lamp which gives off ulraviolet light while blocking out white
light, that causes fluorescent minerals to react.
It is a common mineral which comprises, in pure form, 51.1% calcium and
The term is the commercial name for the mineral fluorite.
It is a bend in multiple rock layers.
It is the name given to the host rock of an ore deposit which is
physically below the ore deposit.
It is the breaking of minerals when put under stress, beside cleavage.
It is a process through which some mineral particles are induced to
make it attached to the bubbles and thereby to float, while others sink.
In this way, valuable minerals in an ore are separated from other
components and concentrated.
It is a process of being melted by heat.
