Tetapi tidak termasuk silika tak jenuhalkalik, dan batuan peralkalin. Halaman ini terakhir diubah pada 6 Desemberpukul 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. Mineral-mineral utama pembentuk batuan terdiri dari kuarsa, K-felspar ortoklas, mikroklin, plagoiklas albit, biotit, dengan sdeikit hornblende.

Selain kehadiran mafic enclaves, diferensiasi magma granitoid dengan kontribusi material mantel diperkuat oleh adanya mineralisasi hidrotermal molybdenum dan uranium di sungai Rampah, Sitahuis. Walaupun demikian, Kompleks Granitoid Sibolga di Sumatra Utara memperlihatkan karateristik yang sangat berbeda, yaitu granitoid tipe-A. The mavma 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.

Dari Wikipedia bahasa Indonesia, ensiklopedia bebas. 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. We look forward to serving you again in !

Ciri-ciri geokimia lainnya adalah granitoid Sibolga cenderung berasosiasi dengan lingkungan tektonik late-orogenic hingga anorogenic serta within plate granite WPG. See you in Thanks for flying with WordPress. It indicates the existence of alow density body of mantle material intruded by a higher density igneous material in the center.

Pluton granitoid Sibolga terletak berbatasan dengan pantai barat Sumatra Utara.

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.
