Oxide Mineral

         Oxide and hydroxide Minerals are a mineral formed from a combination of certain elements with anionic oxide (O2-) and hydroxyl hydroxide (OH-) groups. The reason I wrote Oxides and hydroxides in the Guide to Rock and Minerals book written by Simon, in the book said Okside is always accompanied by Hydroxides for example as shown below.


Oxygen is the most abundant element in the earth's crust. Next illustrated oxygen is the most element in the earth's crust.

                                              
n the chemical elements the oxidant and hydroxide minerals have differences, although not significant. Hydroxide consists of H2O, because it still contains oxygen, many authors combine the types of hydroxide minerals with oxide minerals. Mineral Oxides only consist of O. For more details, please see below:

                                              

Genes of mineral Oxides can be due to Placer and Metarmorf (Hematite), or also because of Hydrothermal (Magnetite) Some of the most common oxide minerals are, corondum  (Al2O3), hematite (Fe2O3) and hausmannit (Mn2O4).

                                 
1. Hematite

It is a mineral that contains elements of iron or Fe, because photos of hematite minerals do not form like perfect crystals, it can be predicted that minerals are formed due to the process of sdimentas. The use of hematite minerals is a red pigment and polishing powder

2.Corondum

Formed due to the metamofrt process that has an environment with a large aluminum content. The use of corondum is an important instrument in mechanical equipment

3. Hausmannit

The main ore for mangnesium but the content in nature is very little or rare. Formed due to the process of metamorft.

B. Hydroxide Minerals

Like oxide minerals, hydroxide minerals are formed by mixing or compounding certain elements with hydroxide (OH-). The formation reaction can also be related to binding with water. Just like oxide, in hydroxide minerals, the main elements in general are metal elements. Some examples of hydroxide minerals are Manganite MnO (OH), Bauxite [FeO (OH)] and limonite (Fe2O3.H2O).


                               


1.Mangnetit

Formed in a hydrothermal manner with a low maturity, it is used as manganese ore

2.Bauksit

Having iron or Fe content so that the metal content is very useful, this mineral can be used as a logan ore. Formed because of the sedimentation process

3.Limonite

Formed magmatically, having metal sheets, it is useful to extract the metal content.

Cara Mengukur Ketebalan Terkoreksi/Mengukur Ketebalan Lapisan

Image
Ketebalan terkoreksi merupakan ketebalan sebuah lapisan yang sebenarnya. Pada umumnya sebuah lapisana akan ditemukan dalam bentuk tererosi, sehingga menyebabkan adanya material yang hilang menyebabkan benruk idealnya menjadi hilang. Oleh karena itu untuk mendapatkan ukuran asli perlu dilakukan pengukuran supaya dapat diketahui potensi lapisa tersebut, atau juga mengukur ketebalan batupabara Para ahli mempunyai beberapa metode yang dapat digunakan oleh para geology muda, metode itu adalah 1.        Menggunaakan Rentangan tali atau jarak Terkoreksi 2.        Menggunaakan metode Jacob staff   1.    Mengunakan Rentangan tali atau jarak terkoreksi               Sebelum menggunakan metode ini perlunya untuk mengetahui prinsip pytagoras yang telah diajarkan di tingkat SD,SMP, SMA prinsip pytagoras tersebut adalah  Gambar 1.

             Mineral oksida dan hidroksida ini merupakan mineral yang terbentuk dari kombinasi unsur tertentu dengan gugus anion oksida (O2-) dan gugus hidroksil hidroksida (OH-). Adapun alasan saya menulis Oksida dan hidroksida karean dalam buku Guide to Rock and Minerals yang dikarang oleh Simon, dalam buku tersebuk kata Okside Selalu disertai dengan Hydroksides contohnya seperti gambar dibawah
