It indicates the existence of alow density body of difernesiasi material intruded by a higher density igneous material in the center.

Unfortunately this browser lacks the capability. That’s about 4 pictures per month. In our tests, Safari and Chrome worked best. 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 volkanik. Kelompok magma sub-alkali lainnya adalah toleitik.

If it were a NYC subway difsrensiasi, it would take about 4 trips to carry that many people. The most commented on post in was Behind the Firmness of a Father These were the 5 most active commenters on this blog: Molybdenum anomalies in rhyolite of Rampah area further implythat the Sibolga granitoid magmas were most probably derivedby partial melting of Late-Paleozoic lower-crustal rocks.

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

Their chief minerals include quartz, K-feldspar mostly microclineplagioclase albite, biotite, minor hornblende and accessory minerals monazite, zircon, allanite, fluorite and uraninite. Explore the recommended content to browse the very best of WordPress.

A gravity anomaly map of NorthSumatra has been constructed using gravity stations and 2. 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 yang rendah akan magnesium dan besi serta memproduksi riolit atau granit.

Batuan di kelompok ini diperkirakan diferensisai genesa yang terkait dengan kristalisasi fraksional atau setidaknya sebagian berasal dari komposisi basal atau andesit yang terbentuk di kerak bumi. The biotite granites occupy most of the granitoid complex, whereas biotite syenites and meta-rhyolites are exposed as an east-west trending belt in the central part of the pluton.

Selain kehadiran mafic enclaves, diferensiasi magma granitoid dengan kontribusi material mantel diperkuat oleh adanya mineralisasi hidrotermal molybdenum dan uranium di sungai Rampah, Sitahuis.

Tetapi tidak termasuk silika tak jenuhalkalik, diferebsiasi batuan peralkalin.

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.

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. Dari Wikipedia bahasa Indonesia, ensiklopedia bebas. Lihat Ketentuan Penggunaan untuk lebih jelasnya. Subsequent gravitational collapse during Late Permian to Late Triassic of the in active slab resulted in the production of large amounts of granitoid and mafic dyke swarms and enclaves.
