Abstract:

The study on Geochronology and Geochemistry of the alkali feldspar granite in Horqin Right Wing Middle Banner of Inner Mongolia. Zircon U-Pb dating demonstrates that the weighted mean 206Pb/238U age for the zircons from the adamellite (syenogranite) is (166±1) Ma,i.e.the Middle Jurassic. The alkali feldspar granite is slightly peraluminous and belongs to the alkaline series. The alkali feldspar granite is characterized by high SiO2(74.80%-76.34%), high alkali (7.94%-8.71%), high TFeO/MgO (13.54-24.28), low CaO(0.10%-0.21%), low MgO(0.08%-0.16%), and TiO2(0.07%-0.10%). The alkali feldspar granite is characterized by a "sea-gull" REE pattern with a significant negative Eu anomaly (0.09-0.17). It is rich in Zr(128.95×10-6-156.32×10-6), Yb(4.93×10-6-5.35×10-6), and Y(40.93×10-6-56.75×10-6), and depleted of Sr(23.16×10-6-37.14×10-6), Ba(186.13×10-6-231.31×10-6) and Ti. Thus, the alkali feldspar granite belongs to A-type aluminous granite. The high Rb/Sr (ranging from 4.26 to 7.81, and the average value is 6.12) and Rb/Nb ratios(ranging from 10.2 to 14.7,and the average value is 12.7) of the rock indicate a crustal origin. The comprehensive analysis shows that the alkali feldspar granite was the product of low pressure felsic crust partial melting. In addition,based on Rb-(Yb+Ta), Rb-(Y+Nb), Ta-Yb, Nb-Y, Nb-Y-Ce, Ce/Nb-Y/Nb, Ce/Nb-Yb/Ta diagrams and combined with regional tectonic evolution, we suggest that the alkali feldspar granite was formed in an extensional setting of the Middle Jurassic orogeny,also the formation of Songliao basin.
