| 摘 要： | 大范围系统的基础地球化学研究国内外均不多见，进行区域地球化学分区仍处在摸索阶段．在区域基础地球化学研究基础上，在长江中下游及邻区利用多元示踪元素（常量元素、高场强元素、基性元素、亲氧碱性元素、成矿元素及性质相似元素比值）和Ｐｂ，Ｎｄ同位素进行不同区域地壳、同一区域地壳内不同级次的地球化学分区，从而厘定了研究区区域地壳的边界，提供了区域远景预测的地球化学依据

| Abstract: | Systematic studies of regional
geochemistry on a provincial scale inside and outside China are rarely seen. In this
sense, the investigation into the regional geochemical subdivision is still in its initial
stage. On the basis of the investigation into the regional basic geochemistry, the authors
have been engaged in the geochemical division of middle and lower reaches of Yangtze River
and neighboring areas in terms of multiple tracer elements (for examples, major elements,
high field-strength elements, basic elements, oxyphile alkaline elements, ore-forming
elements, and the ratios between elements with similar properties) and isotopic
compositions of Pb, Nd in different regional crusts and in different classes of
geochemical subdivision within the same regional crust. Therefore, the present research
clearly delineats the border between regional crusts and presents us the geochemical basis
for the regional metallogenic forecasting. |
