摘要
岩体地质、岩石化学、稀土元素和锶同位素初始比等的研究表明:新路矿田地洼花岗岩与脉岩,属于S型重熔岩浆结晶分异型岩体,脉岩形成过程具有同化混染作用;含锡量及岩石化学特征参数表明:矿田地洼花岗岩为含锡花岗岩,部份脉岩为含锡岩脉。
Researches into geological characteristics of rock body. petrochemistry, rare earth elements and initial Sr isotopic ratio show that the granites and vein rocks formed in the diwa stage in the ore field were derived from S-type re—melted magmas through cystallization-differentiation, and assimilation-contamlnation took place during the formation of vein rocks. Tin content and petrochemical feature suggest that the granites and part of vein rocks are tin-bearing.
