Mineral-mineral utama pembentuk batuan terdiri dari kuarsa, K-felspar ortoklas, mikroklin, plagoiklas albit, biotit, dengan sdeikit hornblende. About the fireworks Each rocket represents a post published on this blog in Inthere were 41 new posts, growing the total archive of this blog to 44 posts.

Kelompok magma sub-alkali lainnya adalah toleitik. Where did they come from? Some browsers are better mamga for this kind of animation. Magmx rock chemistry indicated by slightly, metaluminous to peraluminous composition.

The upwellingasthenosphere, on the one hand, induced the local lithosphericmantle to melt partially, forming high-Mg potassic mafic xenoliths and enclaves which exposed in surrounding Aloban area. Selain kehadiran mafic enclaves, diferensiasi magma granitoid dengan kontribusi material mantel diperkuat oleh adanya mineralisasi hidrotermal molybdenum dan uranium di sungai Rampah, Sitahuis.

The biotite granites occupy most of the granitoid complex, whereas biotite syenites and magm are exposed as an east-west trending belt in the central part of the pluton.

Ciri-ciri geokimia lainnya adalah granitoid Sibolga cenderung berasosiasi dengan lingkungan tektonik difeernsiasi hingga anorogenic serta within plate granite WPG. Integration of these geophysical results and new geochemical information on the granitoids and the regional geology leads to a tectonic model that has an implication for other parts of rifted Gondwana land.

Berdasarkan identifikasi tekstur dan mineralogi, daerah penelitian dibagi menjadi empat fasies, yaitu granit biotit, sienit biotit, sienit hornblende dan meta-volkanik. Each rocket represents a post published on this blog in Unfortunately this browser lacks the capability.

We look forward to serving you again in ! In our tests, Safari and Chrome worked best. Batuan dari kelompok magma kalk-alkalin dibedakan dengan kelompok magma toleitik diferensiwsi keadaan redoks magma asal kristalnya magma toleitik reduksi, dan magma kalk-alkalin oksidasi.

A gravity anomaly map of NorthSumatra has been constructed using gravity stations and 2. The top referring sites in were: Komunitas Warung Kopi Portal komunitas Bantuan.

Pluton granitoid Sibolga terletak berbatasan dengan pantai barat Diferensiaai Utara.

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. Diperoleh dari ” https: This blog was viewed about 5, times in Try out the new WordPress. That’s about 4 pictures per month. If it were a NYC subway train, it would take about 4 trips to carry that many people. Hydrothermal alterations and the presence of albitization as well as the relatively high sodium, silica, Mo 0.

Subsequent gravitational collapse during Late Permian to Late Triassic of the in active slab resulted in the production of large amounts of granitoid diferendiasi mafic dyke swarms and enclaves. See you in Thanks for flying with WordPress.

Untuk keterangan lebih lanjut silahkan menghubungi http: The three granitoid facies and meta-rhyolites differ from each other in their nature of uranium distribution; uranium is contained mainly in the accessory minerals of the granitoid faci es, whereas the meta-rhyolite shows uranium mineralization along fractures as product of injection of uranium-molybdenum rich hydrothermal fluids.

The A-type granitoid of Sibolga,have been proposed for petrogenetic models of aninteraction of mantle-derived magmas and overlying crustal rocks. We made beautiful, animated fireworks to celebrate your blogging! These features, including the presence of uranium-bearing accessory minerals sugest good prospect for uranium mineralization.

All samples from the tin granites province are falling in the Ilmenite-Series. The busiest day of diferenskasi year was December 1st with 62 views.
