摘要
钱家店铀矿床及外围地区含矿目标层位划分不明已成为当前生产和科研迫切需要解决的关键问题.为准确厘定含矿层位,综合运用地层学、沉积学、砂岩型铀成矿理论,采取岩性、测井、古生物和其他多手段相结合的多重地层对比方法,系统分析了含矿目标层位的识别特征和划分依据.研究成果证明目前被统归划分为姚家组的含铀红杂色层可以识别并划分出泉头组、青山口组和姚家组,并在此基础上重新厘定了区域上不同矿体的层位归属和矿化特征.该研究可为松辽盆地南部铀矿勘查突破提供新的找矿思路和地质依据,在此新层位体系下进一步开展成矿规律研究,或许能真正有助于揭示长期以来悬而未决的板状铀矿体成因.
Abstract
The unclear division of ore-bearing targets in Qianjiadian uranium deposit and its surrounding areas has become a key problem that needs to be solved urgently in current production and scientific research.In order to determine the ore-bearing strata accurately,based on the stratigraphy,sedimentology and sandstone-type metallogenic theories,the identification characteristics and classification basis are systematically researched by using lithology,well logging,paleontology and other means.Research results show that the ore bearing target layer can be identified and divided into three horizons:Quantou Formation,Qingshankou Formation and Yaojia Formation(traditional stratigraphic division classifies it as the Yaojia Formation).On this basis,the strata attribution and mineralization characteristics of different ore bodies in the region are redetermined.This study can provide a new idea and geological basis for the progress of uranium exploration in southern Songliao basin.Further study of metallogenic regularity under this new horizon system may really help to reveal the genesis of tabular uranium ore body.
