The noble gas isotopic composition and content data of 2 alkali basalts, 3 lherzolite xenoliths and one clinopyroxene megacryst from the Kuandian region have confirmed the occurrence of a fractionation of noble gases during magmatism. Light noble gases such as He and Ne are high in mobility and appear to be incompatible as …
Surface samples of peridotites and hornblendite mylonites from St. Paul's Rocks, and dredge samples from the flanks of the massif, have been analyzed for Sr, Nd and Pb isotopic ratios and Rb, Sr, and REE concentrations. This data, coupled with previous K and REE data, are used to develop a self-consistent model for the genesis of these ultramafic …

Kuandian granite The Kuandian granite is genetically related to the Kuandian amphibolite, as evidenced by the Nd isotopic data, REE pattern, and the same geochemical character as that of bimo- dal-suite rocks. Trace element partition calculations indi- cate that direct partial melting of the Kuan- dian amphibolite (202-255 ppm Sr) cannot ...

Trace-element abundances and Sr, Nd isotopic compositions have been measured on three megacrysts of clinopyroxene, three of garnet and one of amphibole, as well as their host alkali basalts from the Huangyishan volcano, Kuandian, NE China. The Ce isotopic compositions of three host basalt samples have been also analyzed.

Extensive volcanism is one of the important features of Cenozoic geology in China. Based on temporal-spatial distribution, the volcanism was associated with three major different geological settings: 1) the continental rift basalts in Northeast and North China; 2) the tension-fault basalts on the continental margins of Southeast China; and 3) the collision …
کلمه بازالت به این دلیل استفاده می شود، چون سنگ های پوسته اقیانوسی دارای ترکیباتی همچون سنگ بازالت ها هستند. با این حال، تنها یک روکش سطحی نازک از پوسته اقیانوسی از سنگ بازالت تشکیل شده است.
The Kuandian Basin is located in the northeastern portion of the NCC (Fig. 1 a), the most likely area to have been affected by subduction of the Pacific slab. The Huangyishan volcano (Fig. 1 c) is the largest and most representative of over 20 volcanoes in the Kuandian volcanic field covering an area of nearly 500 km 2. The basement of the ...
