Petrogenesis of high-CaO lavas from Mauna Kea, Hawaii: Constraints from trace element abundances

The role of a mafic component in the petrogenesis of Oceanic Island Basalts (OIBs) is highly debated. As the best studied OIB, Hawaiian lavas provide critical insights into OIB genesis. At a given MgO content, the CaO content in the melt has been used to distinguish between partial melts of peridotite and garnet pyroxenite/eclogite. However, calculations using the BATCH program show that CaO co...

Mineralogy and geochemistry of major, trace and REE elements, Pirashkaft Bauxite Deposits, Mamasani, Fars Province

The Pirashkaft bauxite deposit is located in north of the Paskuhak anticline in the Fars Province. The bauxite deposit present between Sarvak and Gurpy Formations, and formed during the Late Turonian time as a consequent of the Laramid orogeny phase. According to the geological investigations, the Pirashkaft bauxite is  Karstic type. The residual ore studied in the Pirashkaft can be classified ...

Major and trace elements in lithogenesis

The process of crystallization in the urinary tract occurs when the equilibrium between promoting and inhibiting factors is broken. Many theories have been published to explain the mechanism of urinary stones formation; however, none of these theories has paid attention to trace elements. Their role in lithogenesis is still unclear and under debate. The findings of some studies may support the ...
