An important point to note in the discussion of mantle xenoliths is the varying petrographic nomenclature used. Workers studying noncratonic peridotite xenoliths and orogenic peridotites use the … WebXenoliths of gabbro are coarse-grained olivine-bearing with well preserved plutonic igneous textures. SEM-EDS analyses integrated with petrographic studies recorded three types of olivines with different #Mg. Most magnesian are olivine xenocrysts as aggregates, which show textural evidence of reaction with dyke magma.
Web3.5 Intrusive Igneous Bodies. In most cases, a body of hot magma is less dense than the rock surrounding it, so it has a tendency to move very slowly up toward the surface. It does so in a few different ways, including filling and widening existing cracks, melting the surrounding rock (called country rock[1]), pushing the rock aside (where it ... WebScience.

For example, in sedimentary rocks, it is common for gravel from an older formation to be ripped up and included in a newer layer.
WebJan 1, 2013 · Those occurring within lithic clasts (xenoliths and autoliths) and within sedimentary accretionary clasts should be considered and described separately.
