查询词典 rare bird

Basanite and tephrite from Mt. Crater, Cape Bird and Bonney Lake exhibit similar composition in major elements and trace elements, rare earth elements . They are enriched in MgO, TiO〓, transitional elements and compatible elements , and depleted in SiO〓, Al〓O〓, Na〓O, K〓O, incompatible elements and rare earth elements; Latite from Cape Rodeys and Cape Evens are different from basanite and tephrite, they are enriched in SiO〓, Al〓O〓, Na〓O, K〓O, incompatible elements and rare earth elements, and depleted in Mgo, TiO〓, transitional elements and compatible elements. Volcanic rocks in five regions have the same isotopic ratio of 〓Sr/〓Sr (0.703115-0.703334) and 〓Nd/〓 Nd (0.512892-0.513076), however,〓Pb/〓Pb ratio in volanic rocks from Mt. Crater, Cape Bird and Bonney Lake is lower than those of Cape Rodeys and Cape Evens.
