The physical properties of minerals are determined by
the atomic structure and crystal chemistry of the minerals
. The most common physical properties are crystal form, color, hardness, cleavage, and specific gravity. One of the best ways to identify a mineral is by examining its crystal form (external shape).
How do you identify minerals?
Most minerals can be characterized and classified by their unique physical properties:
hardness, luster, color, streak, specific gravity, cleavage, fracture, and tenacity
.

How do geologists identify minerals?
To help with identification, geologists
must look closely at the physical properties of a mineral
. These properties can include: color, streak, hardness, cleavage, specific gravity, crystal form, and others.
What are the 5 properties of minerals?

What are the 10 properties of minerals?
- Color.
- Streak.
- Hardness.
- Cleavage or Fracture.
- Crystalline Structure.
- Diaphaneity or Amount of Transparency.
- Tenacity.
- Magnetism.
What is color in physical properties of minerals?
For example, a mineral described as “shiny
yellow
” is being described in terms of luster (“shiny”) and color (“yellow”), which are two different physical properties. Standard names for luster include metallic, glassy, pearly, silky, greasy, and dull.
What are the two major properties of minerals?
A mineral species is defined by two distinct properties:
(1) its chemical com- position and (2) its crystal structure
. Each mineral has a distinct three- dimensional array of its constituent atoms. This regular geometry affects its physical properties such as cleavage and hardness.
What are the main characteristics of minerals Class 8?
Most minerals can be characterized and classified by their unique physical properties:
hardness, luster, color, streak, specific gravity, cleavage, fracture, and tenacity
.
What are the 2 types of luster?
There are two main types of luster:
metallic and nonmetallic
. There are several subtypes of nonmetallic luster, namely vitreous, resinous, pearly, greasy, silky, adamantine, dull, and waxy.
What are 5 tests geologists do to help identify minerals?
Geologists use the following tests to distinguish minerals and the rocks they make:
hardness, color, streak, luster, cleavage and chemical reaction
.
What are examples of minerals?
Minerals are those elements on the earth and in foods that our bodies need to develop and function normally. Those essential for health include
calcium, phosphorus, potassium, sodium, chloride, magnesium, iron, zinc, iodine, chromium, copper, fluoride, molybdenum, manganese, and selenium
.
What are the properties of minerals?
Minerals can be identified by
their color, luster, streak, cleavage, hardness, and even by their chemical composition
. Using these properties is one way a Geologist defines and identifies what kind of mineral a specimen is.
What is the hardest mineral?
Talc is the softest and
diamond
is the hardest. Each mineral can scratch only those below it on the scale.
How many types of minerals are there?
There are
two kinds of minerals
: macrominerals and trace minerals. You need larger amounts of macrominerals. They include calcium, phosphorus, magnesium, sodium, potassium, chloride and sulfur. You only need small amounts of trace minerals.
