摘要
利用地球化学块体理论和浙江省1/20万水系沉积物测量成果,对主要成矿元素特征、分布范围及目前发现与之相对应的矿点进行总结,将浙江省地球化学场划分为浙西北和浙东南2个地球化学块体,其中浙东南地球化学块体进一步划分为3个亚块体,分别为余姚-龙泉、宁波-泰顺和宁海-温州地球化学亚块体。根据各地球化学块体元素组合、分布区域及受控因素,利用"套合的地球化学模式谱系"进一步明确了各地球化学块体的找矿方向,为下一步找矿勘查提供指导。
The main geochemical characteristics of ore-forming elements,distribution area and corresponding typical ore deposits are concluded based on the theory of geochemical blocks and the results of 1：200,000 stream sediment survey in Zhejiang Province.It is suggested that the geochemical blocks in Zhejiang Province can be divided into two geochemical blocks named as northwest zhejiang block and southeast Zhejiang block,respectively.The southeast Zhejiang block can be further divided into three sub-blocks that Yuyao-Longquan,Ningbo-Taishun and Ninghai-Wenzhou.According to the element association,distribution areas and controlled factors of geochemical blocks,the authors put forward the prospecting directions of each geochemical blocks using the theory of＂hierarchy of geochemical patterns＂,which can provide guidance for the next step prospecting.
