Many minerals are apart of other rocks just like granite. Granite consists of some minerals like Hornblende and Feldspar. Hornblende is a mineral apart of granite that is black, dark green, and brown. The mineral has a streak of a white, grayish color. The reason that Hornblende is apart of granite is because a scratch test was done on the parts of the granite sample that are the same color as hornblende, the streak on those parts of the granite sample were the exact same color as the Hornblende streak, therefore Hornblende is apart of granite. Feldspar is a mineral that is also apart of granite, Feldspar is white, pink and gray. Feldspar has a streak of the color white and is considered nonmetallic. Feldspar is a mineral is granite because the granite sample is mostly consisting of the color pink. These two minerals are only some of the minerals of granite.

Defining a mineral by color is not the most sophisticated method, due to many minerals hold the same color. Also, different imperfections can show different colors within the mineral. Only using color can be difficult to identify a mineral, but when using a combination of shape and hardness one has the ability to narrow down choices. If a mineral reflects light from a surface it is said to have luster, however it does not reflect light such as silver or copper does it would be called glassy, pearly and dull.

The fourth rock I chose is Psilomelane. Psilomelane’s chemical formula is (Ba1H2O) 2Mn5O10. Psilomelane is an important ore of manganese which

Cross-polarized light shows that opal-CT has very low interference colours, in contrast to the brighter colours typical of chalcedony (Mustoe, 2008). However, polarizing microscope images alone cannot resolve the degree of crystallinity of phases. For this, XRD and Raman microscopy are required to clearly identify chalcedony, moganite, orthorhombic-silica, opal-CT, opal-C and quartz (Hatipoğlu and Türk, 2009). It is not easy to

Around the world, we the people, are surrounded by numerous minerals that we might not even be aware of. After researching the minerals sulfur and anapaite, I have come to a conclusion that minerals are an engaging topic to dig into. The two minerals I analyzed had both similar and different qualities. While examining the minerals by using specific character traits I discovered interesting data on each substance.

Witherite, and barite. If we compare the relationship between the weight and the size of the mineral, these two have

(20) Metals are classified variously—according to molecular weight (“heavy metals”), according to chemical properties (periodic table), according to toxicology. Please do the

According to our text, Essential environment: The science behind the stories, a mineral “…is any naturally occurring solid element or inorganic compound with a crystal structure, a specific chemical composition, and distinct physical properties” (P. 230).

Use the chart to determine what physical properties listed best fit your mineral and identify your

A mineral must be solid, inorganic, crystalline, naturally occurring, and have a specific chemical composition.

Bentonite describes a naturally occurring, very fine grained material. It is part of the smectite

The conditions under which a mineral is created can be reflected in its atomic structure and therefore in its physical properties. There are many properties of minerals that scientists use when trying to identify a mineral. Color, streak, hardness, cleavage, crystalline structure, luster, amount of transparency were some that were listed in the video. Some minerals cannot be identified by physical properties but a petrologist is able to further break down the elements to determine the mineral. Petrologists study the composition and structure of

In 1807 Brongniart published Elementary mineralogy Treaty, a work assigned as a textbook for his and Haüy’s courses at the Faculty of Sciences and the Natural History Museum. Like other mineralogists at this time, he could not easily distinguish some fine-grained rocks from true simple minerals.

•it occurs naturally in its pure,free form as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite
