摘要
菱镁矿是辽宁省非常重要的矿种之一,集中分布于辽吉裂谷内,规模巨大,地球化学特征和异常突出明显,成矿条件优越.在辽吉裂谷有利的地质条件基础上,充分利用地质、化探各类找矿标志,应用找矿概率-地球化学块体法在辽吉裂谷内对菱镁矿进行了矿产预测与评价.以地球化学块体为理论依据,划分了菱镁矿地球化学块体,梳理了地球化学块体谱系,最终应用找矿概率-地球化学块体法共圈定11个远景区,其中Ⅰ、Ⅱ、Ⅲ类远景区分别有2个、7个和3个,计算预测资源量为114.1268×108 t.
Magnesite, as a very important mineral in Liaoning Province, is concentrated in the Liaoning-Jilin rift and characterized by large scale, distinct geochemical characteristics features and anomalies and good metallogenic conditions.Based on the favorable geological conditions, the author makes full use of various geological and geochemical prospecting indicators and prospecting probability-geochemical block method to make mineral prediction and evaluation of magnesite in the Liaoning-Jilin rift, divides geochemical block of magnesite and presents geochemical block pedigree with the theoretical basis of geochemical block, and finally delineates 11 prospective areas, including 2 grade Ⅰ, 7 grade Ⅱ and 3 grade Ⅲprospects, with predicted resources of 11.41268 billion tons.
