I introduce my area, as a sign of the wealth of Indonesia
As expressed posts earlier on (Piropilit--Al2Si4O10(OH)2), that piropilit has a white, pale yellow, reddish brown and/or. In post had previously been shown pictures of white color piropilit, grayish the post so on presented the piropilit brown color with reddish brown spots and piropilit white. The two minerals with different colors is found in the quarry's location in the village of piropilit Argotirto Sub Sumbermanjing, Malang. Piropilit reddish brown color and white spots of Brown piropilit this number is not as big a piropilit piropilit which is white and greyish white. Because of different color that is what makes "feel masel" curious
According to Dr. Sunaryo, S.Si., M.Si., Chairman of the Physics Department of Geophysical Studies Programs FMIPA, Brawijaya University was unfortunate that the color red on the sides of piropilit comes from feldspar. Feldspar, piropilit also included in the Group of silicate minerals composed of aluminium and silica. This Mineral is the most common or most minerals found on Earth. Next Dr. Sunaryo explains that the red line (see picture above) that shows the process of perlapisan of feldspar. While the images down, feldspar white patches of Brown, some say that the brown color comes from sewage containing potassium.

THE MATERIAL SLIDES KLIF

I introduce my area, as a sign of the wealth of Indonesia. This is the rock lime hollow sea base results against abrasion/foot a klif. Basic klif continuous for taked by swash and backwash basin or the basic niche resulting klif. The upper part of the basin became unstable. Because of the influence of style weigh in, the top of the niche at the base of klif into collapse. As a result there is wave-cut platform, basic klif into retreat. In a place that's crumbling Foundation of klif teronggok material. If the material extends to form the embankment, then the place is a place ideal for shallow marine organisms.

If you're into beaches will surely be found coral rocks are overlaid in the form of white sand, it's partly from his form.

Minerals Dolomites (CaMg (CO3) 2)

nyachya@gmail.com (the mount) — Wed, 20 Apr 2011 16:55:00 +0000

I introduce my area, as a sign of the wealth of Indonesia. Limestone mountain that stretches to the South of Java has deposits of various minerals. Minerals-minerals are most dominant are the Dolomites (CaMg (CO3) 2). Dolomite is referred to as dolosit by the residents of Malang especially the citizens of Malang South.

Dolomites (CaMg (CO3) 2) including the mineral carbonates. According to Doddy Loyal Graha (1987: 237) that the Dolomites have a hexagonal crystal system;
the perfect {1011};
hardness of 3.5-4,
the weight of 2,85,
glass glassy (vitreous),
the color of the nodes or white to creamy white,
scratch. drain.
These minerals occur in nature as a layer batugamping magnesium, as mineral aisle in veins hidrothermal.

The spread of the Dolomites in Indonesia found at

Kejae (the central part of Sumatra);
Pamotan,
Mt. Sekapuk,
Mt. Kaklak,
Gresik,
Tuban,
Bancak Sedayu,
Madura (province of East Java) and
Tonasa (South Sulawesi).

Utilization of dolomite in everyday life as a refractory, paper industry, fertilizer, building, brick adhesive bangan, adhesives, coatings, glass-making, metallurgical flux as chemicals for the pharmaceutical industry, rubber, paint, printing ink, and pasta.

Difference Igneous Out Products mount Semeru and Kelud Igneous Products

The lithosphere is derived from lithos and sfer/fer/faira. Lithos meaning stone and fer means layers. Thus the lithosphere means rock. Is the science that study it's Geology. A branch of Geology which studies rocks is called Petrology. The branch of Geology which studies the minerals or mineral is called Mineralogy. Was the study of crystals is called Kritalogi.

The lithosphere is often called the skin of the Earth/Earth's crust (crust). The parent of all the rocks in the lithosphere is the magma (molten rock). According to the process of occurrence and its formation, the rock in the face of the Earth are classified into three groups of rocks. Rocks-rocks are:
1. igneous rocks
2. rocks of sedimentary deposits/(other rock)
3. Metamorphic Rocks

Igneous rocks (igneous rock rock) is a rock that is formed because the magma freezes through a process of cooling. Based on the freezing of magma, igneous is distinguished into three kinds, namely:

igneous in (inner igneous rock rock) is formed in igneous magma (batholit), located deep within the Earth and having the process cooling in a very long time. The rock is often called the rocks the rocks of the abisis plutonic rocks/.
igneous korok/gang/porfirik (' korok'igneus rock or hypabyssal rock) are the igneous rocks formed in the korok/gang/the pipes drain a volcano (in diatrema) or in the formation of other intrusion.
igneous out/efusif (outer igneous rock rock/effusive rock) are the igneous rocks formed in the Earth's surface with a relatively quick process of freezing.

For the next study we only leads to igneous. Considering the formation of this rock in a relatively quick, of rocks has its crystal grain characteristics: subtle, even amorphous and partially exposing the holes the former existence of a trapped gas.

One example is andesitic igneous rocks out. Andesite according to Bagja Waluya (2007: 110) was "rock leleran of diorit, fine-grained minerals, the composition mineralnya with diorit, grey". Next Bagja Waluya mentions that the volcano in Indonesia produces rocks andesite lava in the form of piroklastika. A lot of rocks andesite containing hornblende andesite called hornblenda, while many contain piroksin called andesite piroksin.

As such, the two images that according to the rock seems to me is an andesitic rock. The image below is the outer product of igneous mountain most high and most active on the island of Java, i.e. volcanoes Semeru. Characteristics of rock colors gray kehijau-biruan. Are the images of the outer product of igneous kelud which shows the typical grey colour rocks andesite. Both volcano is a mountain range in Central Java to the East, including on the bow of the Sunda arc--Banda, extract from sirkum the Mediterranean. Even the two volcanoes in East Java province was only a straight km in the past, the rocks of the andesite is used for materials of the temple. One example in candi Penataran at mBlitar. Being at the moment, these rocks are widely used for building foundations, paved roads, as well as speaker for the construction of the concrete. Rocks of andesite unsweetened/sheet used for stone decorations on the walls of the settlements are located.
