The Stillwater Complex is one of the world's great layered mafic intrusions, distinguished not so much by its size as by the fact that it is tilted on its side, and erosion has exposed the layering to ready access. This fieldguide presents a summary of the geology of the complex in .

PETROGRAPHY OF IGNEOUS ROCKS Skeletal crystals, generally found in situations where an origin by quench crystallization seems probable, e.g., olivine crystals in high-magnesium basalts, plagioclase microlites in pillow basalts (see Section in Chapter 6), are of varied morphology but, as their name implies, are not "solid".

The Influence of Interfacial Energies on Igneous Microstructures. for chromite grains from the Stillwater complex show a log-linear distribution with negative slope at larger sizes and a. Postcumulus and subsolidus equilibration of chromite and coexisting silicates CONCLUSIONS I would conclude, from data at hand, t h a t while there are features t h a t indicate local equilibration both in postcumulus and subsolidus systems, this is not the cause of the main variation in composition of chromite and coexisting ferromagnesian Cited by: T he Rum Palaeogene Central Complex, northwest Scotland, forms the hills of the Rum Cuillin and their immediate surroundings and its evolution is summarized in Table Central Complex consists of an exceptionally well exposed suite of ultrabasic, basic and gabbroic rocks and granitic intrusions accompanied by rhyolitic and rhyodacitic intrusions and extrusives in a dissected caldera, all Cited by: Full text of "Igneous rocks and processes [electronic resource]: a practical guide" See other formats.

Here, we present a geochemical and petrological study of a suite of kyanite- and corundum-bearing eclogites from the Bellsbank kimberlite, S. Africa, which originate from depths between and km. Although clearly of high-pressure provenance, these rocks had a low-pressure cumulative origin with plagioclase and olivine as major cumulate.
