Inclusion vs intrusion geology
WebAs nouns the difference between intrusion and extrusion is that intrusion is the forcible inclusion or entry of an external group or individual; the act of intruding while extrusion is a manufacturing process where a billet of material is pushed and/or drawn through a die to create a shaped rod, rail or pipe. WebIn geology terms the difference between intrusive and intrusion is that intrusive is an igneous rock that is forced, while molten, into cracks or between other layers of rock while intrusion is magma forced into other rock formations; the rock formed when such magma solidifies.

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…
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. WebAn Introduction to Geology.

The simplest and most intuitive way of dating geological features is to look at the relationships between them. There are a few simple rules for doing this, some of which we’ve already looked at in Chapter 6.
