黑龙江明礼地区多金属矿成矿地球化学环境初步评价

The preliminary evaluation of polymetallic ore-forming geochemical environment in Mingli area of Heilongjiang Province

东北地区地处欧亚板块与太平洋板块的相结合部位,构造活动自古生代以来就极其活跃。构造活动的同时,各种矿物源不断的从地壳深部上涌至近上地壳或地表,在东北地区形成了一个以铁、铅、锌、钨、钼为主,金、银为辅的多金属成矿区。作为东北地区重要的多金属成矿之一的宾东地区,其地球化学环境特征的研究对于整个区域未来的地质、矿产勘探工作来说都有较为重要的意义。笔者通过对明礼地区的土壤进行化探取样,对其地球化学环境做初步评价和建议。

The Northeast region is located in a joint between the Eurasian plate and the Pacific plate.Since Paleozoic its tectono-magmatic activity is extremely active.With these tectonic activities were bring aboundant mineral resources from the deep crust to surface,leading to forme a polymetallic metallogenic area with main iron,lead,zinc,tungsten,molybdenum,and subsequent gold,silver.In Bindong area,as an important polymetallic mineralization in northeastern China,the research about the geochemical environment is greatly significant to the whole region.This paper aims to make a preliminary evaluation of its geochemical environment by the analysis of soil geochemical exploration,and to provide several suggestions for the further works in Mingli area.
