Potassic igneous rocks have won a lot awareness between petrologists around the world, as a rule because of their certain geochemistry, and lots of geoscientists nonetheless contemplate them as petrological curiosities with an vague petrogenesis. long ago, a plethora of genetic hypotheses and of neighborhood names for potassic igneous rocks from various localities were created. This has produced a few confusion within the literature. This publication reports the geochemical and petrological features of the potassic igneous rock complexes and investigates the various tectonic settings during which those rocks ensue. The authors supply an outline and a type of those rocks and try and elucidate the geochemical modifications among barren and mineralized potassic igneous complexes. Many epithermal gold and porphyry copper-gold deposits are hosted via high-K rocks. for this reason, this e-book isn't just correct to educational petrologists engaged on alkaline rocks, but in addition to exploration geologists prospecting for epithermal gold and/or porphyry copper-gold deposits in smooth and historical terranes. This 3rd, up to date and enlarged variation includes numerous new sections, new geochemical info and extra references.
