Lithophile Elements

Lithophile Elements

 

chemical elements of rock. They include 55 elements of the periodic system: O, Si, Al, Ti, B, C, all the alkali and alkaline-earth metals, the halogens, and many of the rare elements. The lithophile elements make up about 93 percent of the mass of the entire crust of the earth and about 97 percent of the salt content of the ocean waters—products of rock weathering dissolved in water. According to the classification of the Soviet geochemist A. P. Vinogradov, all the atmophile elements are also included among the lithophile elements.

Multi-elemental patterns normalized to the primitive mantle of (Sun and McDonough, 1989) (FIGURE 7A) yielded a relative enrichment of large ion lithophile elements (LILE) such as Ba, Rb, Sr and Th and well-defined negative Nb, P, and Ti anomalies, the high normalized HREE reveals no residual garnet in the melt and therefore is more akin to shallower melting conditions.
The spider diagrams of both Deosai volcanics and the meta-volcanics of the Burji-La Formation exhibit enrichment of large ion lithophile elements as compared to high eld strength elements while well-dened negative and positive anomalies have been observed for Nb and Sr respectively.
This investigation was carried out for five groups, (1) major and minor elements, (2) large ion lithophile elements (LILE), (3) transition trace elements (TTE), (4) high field strength elements (HFSE), and (5) rare earth elements (REEs).
An exception is a group of closely correlated lithophile elements, most specifically Al, Si, Ti, K, Rb, and Zr (less closely correlated Mg, Zn, Cu).
2 show increasing ionic potential from left to right, with K, Na, Rb, Ba, and Sr representing the large ion lithophile elements (LILE: Z/r < 2), and La-Yb the mostly trivalent lanthanoid (rare earth) elements (which can be grouped with Y which behaves like Yb).
Thus, when one of these high-field strength lithophile elements is present in large amounts (or small amounts) in a wine, all such elements tend to be present in large (or small) amounts.
Many minor gold-bearing quartz veins, some containing elevated contents of lithophile elements, occur along with fluorite deposits in the Mesozoic extensional province of northeastern Mongolia[3].
On the basis of major and trace element chemistry and the enrichment in large ion lithophile elements relative to high field strength element with well-defined negative Nb anomaly the rocks of the study area are comparable to the subduction related calc-alkaline rocks of island arc type setting.
This suggests that metasomatic fluids or melts carry large ion lithophile elements to their sources a short time prior to melt extraction.
Trace-elements: The trace element data of porphyritic volcanic rocks in Table 2 indicate that the large ion lithophile elements (LILE) such as Sr (244-457 ppm) Rb (12-20 ppm) Ba (117-188 ppm) and high field strength elements (HFSE) such as Th (1-2 ppm) U (up to 1 ppm) Nb (1-2 ppm) Zr (23- 47 ppm) Hf (1-3 ppm) and Y (17-19 ppm) have less variation in concentration.
Trace element abundances Large Ion Lithophile Elements (LILE): The volcanics generally have higher abundances of LILE as compared to high field strength elements (HFSE).
