These features, including the presence of uranium-bearing accessory minerals sugest good prospect for uranium mineralization. Granit biotit mencakup fasies yang terluas di magam penelitian, sedangkan sienit biotit dan meta-volkanik terdapat dibagian tengah dengan arah penyebaran barat-timur.

Mekanisme pembentukan yang diajukan peneliti adalah akibat pencairan parsial dari material tersubduksi dan peridotit mantel olivin dan piroksin yang terubah oleh air dan lelehan yang berasal dari material subduksi. Tampilan Baca Sunting Sunting sumber Versi terdahulu.
We look forward to serving you again in ! Hydrothermal alterations and the presence of albitization as well as the relatively high sodium, silica, Mo 0.
Igneous in Indonesian – English-Indonesian Dictionary – Glosbe
We made a slide show to fill in but we hope you will come back to this page with an HTML5 browser. Their chief minerals include quartz, K-feldspar mostly microclineplagioclase albite, biotite, minor hornblende and accessory minerals monazite, zircon, allanite, fluorite and fiferensiasi.
Selain kehadiran mafic enclaves, diferensiasi magma granitoid dengan kontribusi material mantel diperkuat oleh adanya mineralisasi hidrotermal molybdenum dan uranium di sungai Rampah, Sitahuis. Lihat Ketentuan Penggunaan untuk lebih jelasnya. Crunchy numbers A New York City subway train holds 1, people. Kebanyakan penjelasan yang ada fokus pada kandungan air dan keadaan oksidasi magma.
Batuan di kelompok ini diperkirakan memiliki genesa yang terkait dengan kristalisasi fraksional atau setidaknya sebagian berasal dari komposisi basal atau andesit yang terbentuk di kerak bumi.
The facts of extensive outcrop of mafic dyke mgma and enclaves surrounding Aloban area support also the contribution diferensias granitoid magma mingling with the upper mantel materials. Ciri-ciri geokimia lainnya adalah granitoid Sibolga cenderung berasosiasi dengan lingkungan tektonik late-orogenic hingga anorogenic serta within plate granite WPG. If it were a NYC subway train, it would take about 4 trips to carry that many people. Unfortunately this browser lacks the capability. Batuan kalk-alkalin biasanya ditemukan di busur diatas zona subduksi biasanya busur vulkanik terutama yang berada diatas lempeng benua.

The most commented on post in was Behind the Firmness of a Father These were the 5 most active commenters difefensiasi this blog: Pulsatory injection of suchhigh-temperature magmas into the mafic mantel crustal sourceregion induced them to partially melt and generate the A-typemagmas of the Sibolga granitic rocks. Magmq rock chemistry indicated by slightly, metaluminous to peraluminous composition.
Batuan dari kelompok magma kalk-alkalin dibedakan dengan kelompok magma toleitik oleh keadaan redoks magma asal kristalnya magma toleitik reduksi, dan magma kalk-alkalin oksidasi. Mineral asesoris disusun oleh zirkon, monasit, alanit, garnet, apatit, florit, dan uraninit. A New York City subway train holds 1, people.
Granitoid Sibolga mengintrusi batuan meta-sedimen berumur Karbon Formasi Kluet. It indicates the existence of alow density body of mantle material intruded by a higher density igneous material in the center. In our tests, Safari or Chrome worked best. Tipe-tipe batuan di kelompok kalk-alkali termasuk tipe-tipe vulkanik seperti basalandesitdasitriolitdan juga ekuivalen intrusif nya gabrodioritgranodioritdan granit. Dibantu dengan bukti-bukti dilapangan berupa himpunan mafic enclaves dan senolit di sungai Bair, daerah Aloban, granitoid tipe-A mengindikasikan pengaruh interaksi antara magma dengan mantel bagian atas.
How did they find this blog? Berdasarkan identifikasi tekstur dan mineralogi, daerah penelitian dibagi menjadi empat fasies, yaitu granit biotit, sienit biotit, diferensiaai hornblende dan meta-volkanik. Untuk diferensiaso lebih lanjut silahkan menghubungi http: Other geochemical signatures suggest that the granitoid belong to transisitional environment between late orogenic and anorogenic as well as within plate environment.

Ketika magma mafik magma yistalisasi, mereka memiilih mengkristal menjadi mineral silikat yang kaya magnesium dan miskin besi seperti olivin dan piroksenmenyebabkan kandungan besi magma toleitik meningkat ketika pencairan dihilangkan dari kristal-kristal miskin besi.
In our tests, Safari and Chrome worked best. Kelompok magma adalah kelompok komposisi yang menggambarkan evolusi magma mafikyang tinggi akan magnesium dan besi serta memproduksi basal atau gabrohingga mengalami kristalisasi fraksional menjadi magma felsik difwrensiasi rendah akan magnesium dan besi serta memproduksi riolit atau granit.
Batuan kalk-alkali kaya akan alkali tanah magnesia dan kalsium oksida serta alkali metal yang mendominasi kerak-kerak benua.
