On Tuesday 07/05/2013, I did the mineralogy labwork class for the eight term in this semester. Below was my note of my sulfide-minerals identification :I identify the mineral sample numbered: M34
The color was Green
The streak was White
The luster was Waxy
The hardness was approximately between 2,5 to 3 , because it could be scratched by a nail.
The cleavage was None
The fracture was Even
The diaphenity was Opaque
This mineral was tend to be Parramagnetic
The system of the crystal was AmorphousPicture:
After I compared the data that had been taken in labs, I argued that there were similarities on Serpentine because of because of it was specific colour, hardness, and luster. And, this mineral is economically valuable because it was can be used as precious stones and medical therapy. Genesis serpentine was the process of hydrothermal alteration minerals FerroMagnesian (Fe, Mg) such as olivine, pyroxene, amphibol. But primarily olivine.

On Tuesday 07/05/2013, I did the mineralogy labwork class for the eight term in this semester. Below was my note of my sulfide-minerals identification :
I identify the mineral sample numbered: M52
The color was Black
The streak was Black
The luster was Sub-Metallic
The hardness was approximately between 5,5 to 6 , because it could be scratched by steel blade
The cleavage was None
The fracture was Uneven
The diaphenity was Opaque
This mineral was tend to be Parramagnetic
The system of the crystal was Tetrahedal
Picture:
After I compared the data that had been taken in labs, I argued that there was/were any/some different/similarities on Mangan because of it was specific colour, hardness, luster and our hand would be dirty if touched
And, this mineral is economically valuable because Manganese was also used for the production of dry batteries, ceramic, glass and Steel industrial raw materials.
Manganese genesis formed by the volcanic activity (magmatism 20%) which was then associated with Limestone Manganese. Besides the amount of manganese was largely formed at sea in the form of nodules or balls associated with igneous volcanology results submarine volcano.

On Tuesday 07/05/2013, I did the mineralogy labwork class for the eight term in this semester. Below was my note of my sulfide-minerals identification :
I identify the mineral sample numbered: M50
The color was White
The streak was White
The luster was Vitreous
The hardness was approximately between 5,5 to 6 , because it could be scratched by glass
The cleavage was None
The fracture was Conchoidal
The diaphenity was Translucent
This mineral was tend to be Diamagnetic
The system of the crystal was Trigonal
Picture:
After I compared the data that had been taken in labs, I argued that there was/were any/some different/similarities on Quartz because of it was specific colour, hardness, luster
And, this mineral is economically valuable because quartz used as glass raw materials , optics, ceramics, industrial paints, cement, some precious stones and medical therapy.
Quartz mineral formation process through which the acidic magma freeze after the magmatism along with a decrease in temperature due to the absorption of heat by the rock and the pressure drop due to increase distance from the magma chamber so minerals quartz formed

On Tuesday 07/05/2013, I did the mineralogy labwork class for the eight term in this semester. Below was my note of my sulfide-minerals identification :
I identify the mineral sample numbered: M50
The color was Yellow
The streak was Greenish Black
The luster was Metallic
The hardness was approximately between 3,5 to 4 , because it could be scratched by coins
The cleavage was None
The fracture was Even
The diaphenity was Opaque
This mineral was tend to be Parramagnetic
The system of the crystal was Orthorombic
Picture:
After I compared the data that had been taken in labs, I argued that there was/were any/some different/similarities on Calchopyrite because of it was specific colour, hardness, luster
And, this mineral is economically valuable because As the primary copper ore mineral and Chalcopyrite also produces byproducts , namely gold and silver .
Mineral chalcopyrite was one type of sulfide minerals formed from compound elements Cu, Fe and S that occured due to hydrothermal process, in which magma in the form of volatile element in the form of gases and vapors that contain elements of S, Fe, and Cu were reacted with elements derived from hydrothermal solutions.

On Tuesday 07/05/2013, I did the mineralogy labwork class for the eight term in this semester. Below was my note of my sulfide-minerals identification :
I identify the mineral sample numbered: M33
The color was Green
The streak was White
The luster was Dull
The hardness was approximately between 3 to 3,5 , because it could be scratched by needle
The cleavage was None
The fracture was Even
The diaphenity was Opaque
This mineral was tend to be Diamagnetic
The system of the crystal was Amorf
Picture:
After I compared the data that had been taken in labs, I argued that there was/were any/some different/similarities on Zeolith because of it was specific colour, hardness, luster
And, this mineral is economically valuable because reduce levels of iron and manganese in the water, Increasing levels of oxygen and fertilization.
Zeolites were formed due to volcanic ash sedimentation on alkaline lake environments (salt water), process disgenetik (metamorphosis low level), and the process didrotermal. Generally these sediments millions of years old.

On Tuesday 07/05/2013, I did the mineralogy labwork class for the eight term in this semester. Below was my note of my sulfide-minerals identification :
I identify the mineral sample numbered: M48
The color was Yellow
The streak was Black
The luster was Metallic
The hardness was approximately between 6 to 7 , because it could be scratched by steel fisted
The cleavage was None
The fracture was Conchoidal
The diaphenity was Opaque
This mineral was tend to be Parramagnetic
The system of the crystal was Isometric
Picture:
After I compared the data that had been taken in labs, I argued that there was/were any/some different/similarities on Pyrite because of it was specific colour, hardness, luster
And, this mineral is economically valuable because Phyrite used in the manufacture of sulfuric acid and sulfur dioxide , dust grains of pyrite has been used to recover iron , gold , copper , chemical element / cobalt , nickel . It could be used to make inexpensive jewelry items .
Pyrite could be formed as a result of primary sulfur reduction by soil organisms and water containing iron ions. It influenced by the supply of primary sulfur has been reduced, the iron ion and a suitable place for the establishment.
