WebFeb 28, 2024 · An inclusion is any rock fragment found in or enclosed in another rock. In igneous rock, we call inclusions xenoliths. If the inclusion is a mineral crystal (or crystal fragments), we call it a xenocryst. On the other hand, inclusions in sedimentary rock are clasts or rock fragments. Webv t e The law of included fragments is a method of relative dating in geology. Essentially, this law states that clasts in a rock are older than the rock itself.

WebMay 1, 2008 · SummaryThe intrusion-centered, polymetallic Plaka ore system, Lavrion, Greece, is genetically related to the emplacement of a Miocene biotite ± hornblende granodioritic body and granodiorite porphyry dikes/sills within metamorphic Mesozoic rocks of the Attic-Cycladic Crystalline Belt. The ore system includes porphyry, breccia-type, … The ultimate source of magma is partial melting of rock in the upper mantle and lower crust. This produces magma that is less dense than its source rock. For example, a granitic magma, which is high in silica, has a density of 2.4 Mg/m , much less than the 2.8 Mg/m of high-grade metamorphic rock. This gives the magma tremendous buoyancy, so that ascent of the magma is inevitable onc…
