Pubs Warehouse Home > Browse > Article > Journal Article > Earth. Browse the USGS Publication Warehouse Publications in the Series Earth. What determines the downstream evolution of turbidity currents?, , Earth and Planetary Science Letters () -.

During the period to , the large number of papers, books, and monographs published on the petrology and geochemistry of igneous rocks reflects the vitality and continued growth of this central earth science discipline. While an attempt has been made to prepare a reasonably complete bibliography, the accompanying text, of necessity, reflects a subjective selection of .

In the contact metamorphic aureole of the Duluth Complex, Cu-Ni-PGE mineralization occurs locally up to m from the intrusion-footwall contact (Spruce Road area), whereas elsewhere (Dunka Pit deposit) the footwall granite and metapelite (Serpentine deposit) are barren. This study aimed to understand the effect of temperature and halogen fugacity variations on the presence Author: Zsolt Benkó, Aberra Mogessie, Ferenc Molnár, Steven A. Hauck, Mark J. Severson, Karl Ettinger. gold and other heavy minerals found thus far on the Oregon Continental Shelf. The river appears to be a major source of heavy minerals, and therefore a de­ tailed study of its drainage basin is being made by S. M. Boggs, Jr., and E. M.

The origin of chromitites in the Bushveld Complex has been attributed to two principal mechanisms: (1) gravity-controlled settling of chromite onto the chamber floor from magma that was saturated in chromite, either initially or owing to some internal process; or (2) gravity- and size-controlled separation of chromite from coexisting olivine and orthopyroxene Cited by: Equilibrium It is useful to distinguish between two aspects of ­equilibrium: thermal equilibrium and chemical equilibrium.

Thermal equilibrium All parts of a system in thermal equilibium have the same temperature: in these circumstances heat flowing from one part of the system, A, to another part, B, is exactly balanced by the heat passing.
