2011 in blogging

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 dierensiasi. Granitoid Sibolga mengintrusi batuan meta-sedimen berumur Karbon Diferehsiasi Kluet.

We look forward to serving you again in ! A gravity anomaly map of NorthSumatra has been constructed using gravity stations and 2. The most commented on post in was Behind the Firmness of a Father. 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.

About the fireworks Each rocket represents a post published on this blog in Each rocket represents a post published on this blog in How did they find this blog? Batuan kalk-alkali kaya akan alkali tanah magnesia dan kalsium oksida serta alkali metal yang mendominasi kerak-kerak benua.

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 comprehensive petrology and geochemical analyses that coupled with Diferrensiasi Paleozoic-Mesozoic history of Sumatra, suggested that the A-type granitoid of Sibolga associated with anorogenic or rift related environment.

Molybdenum anomalies in nagma of Rampah area further implythat the Sibolga granitoid magmas were most probably derivedby partial melting diefrensiasi Late-Paleozoic lower-crustal rocks. Your overall score is not known details.

These features, including the presence of uranium-bearing accessory minerals sugest good prospect for uranium mineralization. The maps density variation with depth constructed from 3D deconvolution of gravity anomalies and a 2.

Pluton granitoid Sibolga maga berbatasan dengan pantai barat Sumatra Utara. Komunitas Warung Kopi Portal komunitas Bantuan. Mineral-mineral utama pembentuk batuan terdiri dari kuarsa, K-felspar ortoklas, mikroklin, plagoiklas albit, biotit, dengan sdeikit hornblende. We made beautiful, animated fireworks to celebrate your blogging!

It indicates the existence of alow density body of mantle material intruded by a higher density igneous material in the center. Batuan kalk-alkalin biasanya ditemukan di busur diatas zona subduksi biasanya busur vulkanik terutama yang berada diatas lempeng benua.

Their chief minerals include quartz, K-feldspar mostly microclineplagioclase albite, biotite, minor hornblende and accessory minerals monazite, zircon, allanite, fluorite and uraninite. The top referring sites in were: The A-type granitoid of Sibolga,have been proposed for petrogenetic models of aninteraction of mantle-derived magmas and overlying crustal rocks.

Injeksi magma bertahap dari kerak bagian bawah bertemperatur relativ tinggi dan membawa material mantel yang sepenuhnya belum padat kemungkinan menyebabkan magma mingling dan asimilasi yang menghasilkan komposisi granitoid tipe-A. Asal muasal granitoid tipe-A di Sibolga kemungkinan berasosiasi dengan saat mulai pecahnya kontinen besar Gondwana pada Perm Akhir-Trias Akhir yang dilanjutkan dengan pembentukan jalur intrusi dan diferendiasi.

There were 44 pictures uploaded, taking up a total of 3 MB. Kelompok magma sub-alkali lainnya adalah toleitik. 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. Berdasarkan identifikasi tekstur dan mineralogi, daerah penelitian dibagi menjadi empat fasies, yaitu granit biotit, sienit biotit, sienit hornblende dan meta-volkanik.

You may start scrolling! Selain kehadiran mafic enclaves, diferensiasi magma granitoid dengan diferenssiasi material mantel diperkuat oleh adanya mineralisasi hidrotermal molybdenum dan uranium di sungai Rampah, Sitahuis.
