Mount Bromo, The Fairy Tale from East Java
Bromo have known by all of visitor of the worlds. They come to Bromo to watch the sunrise. The visitor also can look down to the crater that full of its smoke, and feel the cold of the air, is probably could only be done in Bromo. Our eyes will also completed by the sea of sand that the way to reach Bromo's peak. The main gate to the sea of sand and mount Bromo is through Cemorolawang.

Energi Panas Bumi
Energi Geo (Bumi) thermal (panas) berarti memanfaatkan panas dari dalam bumi. Inti planet kita sangat panas- estimasi saat ini adalah,500 celcius (9,932 F)- jadi tidak mengherankan jika tiga meter teratas permukaan bumi tetap konstan mendekati 10-16 Celcius (50-60 F) setiap tahun. Berkat berbagai macam proses geologi, pada...

Gold Ore in Mine
Gold is found widely diffused in nature even though it is one of the scarcer metals. Most people think of finding gold nuggets. The truth is that very little comes from nuggets – nearly all newly mined gold comes from ores mined from the natural hard rocks that contain gold in tiny, even microscopic particles. This webpage is created to show what some of those ores look like.

Gold Ore in Mine
Gold deposits in the western United States are most frequently found mixed within iron ore deposits so look for dark and rust colored iron ore. You will want to chip out the iron ore rock and crush it, so that it can be separated. Iron ore accounts for approximately 5 percent of the Earth’s crust. Iron rusts easily when exposed to oxygen and gets it’s redish hue.
Densities of materials
In the photo to the right the dull black or dark gray is a combination of silver lead and zinc. Again the red rock gets it’s color from oxidized iron. Gold can be found mixed with the iron, but the higher concentration of gold will be found in the brown rock, which is mixed in with the black rock. Also next to the yellow sulfur you can see some brown rock (circled in blue) and that rock also shows evidence of gold.
Sometimes gold is found in tiny specs scattered through slate and some sedimentary rocks like limestone. The gold was placed there by the flow of heated and mineralized waters. Sulfur is often a transporter of gold. So it’s not surprising that native gold is also very commonly found within sulfide minerals such as pyrite. Pyrite can contain up to 30% of gold content. Iron pyrite acts as a reducing agent. This means that the pyrite won’t bond with the gold. So, whenever gold is found in pyrite, it is always present as free milling gold.
Pembentukan Minyak Bumi
Macqiur (Perancis, 1758) merupakan orang yang pertama kali mengemukakan pendapat bahwa minyak bumi berasal dari tumbuh-tumbuhan. Kemudian M.W. Lamanosow (Rusia, 1763) juga mengemukakan hal yang sama. Pendapat di atas juga didukung oleh sarjana lainnya seperti, New Beery (1859), Engler (1909), Bruk (1936), Bearl (1938) dan Hofer. Mereka menyatakan bahwa: “minyak dan gas bumi berasal dari organisme laut yang telah mati berjuta-juta tahun yang lalu dan membentuk sebuah lapisan dalam perut bumi.”
Barthelot (1866) mengemukakan bahwa di dalam minyak bumi terdapat logam alkali, yang dalam keadaan bebas dengan temperatur tinggi akan bersentuhan dengan CO2 membentuk asitilena. Kemudian Mandeleyev (1877) mengemukakan bahwa minyak bumi terbentuk akibat adanya pengaruh kerja uap pada karbida-karbida logam dalam bumi. Yang lebih ekstrim lagi adalah pernyataan beberapa ahli yang mengemukakan bahwa minyak bumi mulai terbentuk sejak zaman prasejarah, jauh sebelum bumi terbentuk dan bersamaan dengan proses terbentuknya bumi. Pernyataan tersebut berdasarkan fakta ditemukannya material hidrokarbon dalam beberapa batuan meteor dan di atmosfir beberapa planet lain 2).

Mount Bromo, A Fairy Tale from East Java
Bromo have known by all of visitor of the worlds. They come to Bromo to watch the sunrise. The visitor also can look down to the crater that full of its smoke, and feel the cold of the air, is probably could only be done in Bromo.

To get to the peak Bromo with its largely open crater, which belch of smoke expelling from its bottom. Mount Bromo has settled by Tenggerese for about thousands years. They who are good of God follower and always do their custom strickly, has historical relationship with Majapahit. The Antropologist from our country or other country are interesting to do some research, because the Tenggerese are strickly in keeping custom for centuries, without influenced by world's change. So there so many version of the unique of Tenggerese in Probolinggo, it can be in the forth of tale, folktale, serat and kidung, legend and science report. [East Java]
