Normal mid oceanic ridge basalts (NMORB)-normalized plots of dolerites, olivine dolerites and lamprophyres show higher enrichments of large ion lithophile elements
(LILEs) relative to high field strength elements (HFSEs) and marked positive anomalies on Nb which confirm their origins from an enriched mantle source.
A spider diagram of the portions of rare earth elements, lithophile elements
, and high-field-strength elements with respect to the Chinese continental crust trace elements is shown in Figure 8.
The contents of large ion lithophile elements
(LILE) Rb, Sr, Cs, and Ba are markedly lower than those in the Earth's crust (Wedepohl, 1995).
This fact is probably determined by soil particles transportation (in relation to lithophile elements
), as well as the transfer of aerosols from Baikal lake, the waters of which contain high concentrations of Ca, Na, Mg, K, Si, and P.
The lithophile elements
(Ca) and a number of chalcophile elements (e.g., Cu, Zn, Ag, and Cd) exhibit moderate correlations between each other (Figure 4(a)), thus suggesting that they share the same source.
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).
First, the high-field strength lithophile elements
, U, Th, La and Ce plot close together on the MDS diagram (Fig.
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.
Quartz diorite and granodiorite are both enriched in large ion lithophile elements
. Compared with depleted high-field-strength elements, they show notable characteristics of depleted Nb and Ta, which is similar to that of island arc magmatite in subduction zone; both of their mineral compositions are generally consistent with those of amphibole calc-alkaline granitoid (ACG) under the mechanism of subduction (Lei et.
All geochemical characteristics of adakite found in literature also apply to the Zanbil adakites, such as: Sr>400 ppm, MgO<3 %, [Al.sub.2][O.sub.3]>15 %, Si[O.sub.2]>56 %, enrichment in light rare earth elements (LREE) and large lithophile elements
(LILE), depletion in heavy REE (HREE) and Y, and high La/Yb>20 and Sr/Y>40 ratios (Kohnavard, 2015).
