摘要 

本地区是金矿一级成矿远景区,本区北、东部做过一些化探面积性工作,但由于对该区的景观地球化学条件分析研究不够和微量金的分析手段所限,影响了化探效果。为了有效地进行金矿普查评价,使用中子活化分析微量金,取得了较好的效果。

Abstract

Gold was determined by neutron activation method and then used as a direct indicator element for gold deposits in a promising gold area of Shandong Province; some encouraging data obtained in this test are summarized in this paper. The sensibility of neutron activation method for gold is 10-8 and the efficiency is 9 samples per diem.Induced potential methlod was also performed in this area. In Hedong mining district, a geochemical anomalous zone delimited by a threshold of 0.68g (gold)/t coincided satisfactorily with the induced potential anomaly and the ore body itself; in Wanger shan mining district, the geochemical anomaly was also in conformity with the ore body whereas no induced potential anomaly was recorded; in induced potential anomalies of an unknown area, gold as determined by neutron activation method detected two anomalies (No. Iand No. II), drilling has already discovered an ore body within No. 1 anomaly and will continue to verify the reliability of No. 2 anomaly.
