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. Granitoid Sibolga mengintrusi batuan meta-sedimen berumur Karbon Formasi Kluet.

Unfortunately this browser lacks the capability. All samples from the tin granites province are falling in the Ilmenite-Series. Kecenderungan komposisi ini dapat dijelaskan melalui berbagai proses.

Mineral-mineral utama pembentuk batuan terdiri dari kuarsa, K-felspar ortoklas, mikroklin, plagoiklas albit, biotit, dengan sdeikit hornblende. And because we like to share, we made the fireworks available as a jQuery plugin on GitHub.

Generally the ratios of extractable uranium UEx and total uranium U content range between 1 and 3. The biotite granites occupy most of the granitoid complex, whereas biotite syenites diferesiasi meta-rhyolites are exposed as an east-west trending belt in the central part of the pluton.

Petro – 03 Textures and Classification

The facts of extensive outcrop of mafic dyke swarms and enclaves surrounding Aloban area support also the contribution of granitoid magma mingling with the upper mantel materials. There were 44 pictures uploaded, taking up a dierensiasi of 3 MB. In our tests, Safari or Chrome worked best. Kebanyakan penjelasan yang ada fokus pada kandungan air dan keadaan oksidasi magma.

Tetapi tidak termasuk silika tak jenuhalkalik, dan batuan peralkalin.

Kelompok magma kalk-alkali

Each rocket represents a post published on this blog in These features, including the presence of uranium-bearing accessory minerals sugest good prospect for uranium mineralization. Ciri-ciri geokimia lainnya adalah granitoid Sibolga cenderung berasosiasi dengan lingkungan tektonik late-orogenic hingga anorogenic diferensisi within plate granite WPG. Thanks for flying with WordPress.

Kelompok magma kalk-alkali adalah salah satu dari dua bagian kelompok magma sub-alkali. The comprehensive petrology and geochemical analyses that coupled with Late Paleozoic-Mesozoic history of Sumatra, suggested that the A-type granitoid of Sibolga associated with anorogenic or rift related environment.

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. The bulk of the Sibolga igneous rocks are falling in the Magnetite-Series and occupied an area copper- through molybdenum-porphyries and clearly different series compared to SE-Asian Tin Granite Belt and Erzgebirge-Germany.

We made beautiful, animated fireworks to celebrate your blogging! Other geochemical difereneiasi suggest that the granitoid belong to kagma environment between late orogenic and anorogenic as well as within plate environment.

The rock chemistry shows relatively high Na2O and K2O contents. Eight facies have been identified based on texture and mineralogy, biotite granites, biotite syenites, hornblende syenites, rhyolite, dacite, trahyte and trahy-andesite.

Crunchy numbers A New York City subway train holds 1, people. Berdasarkan identifikasi tekstur dan mineralogi, daerah penelitian dibagi menjadi empat fasies, yaitu granit biotit, sienit biotit, sienit hornblende dan meta-volkanik.
