内蒙古巴林左旗老毕家营子H_Z-10化探异常地质特征及查证效果
|
摘要
HZ-10异常是内蒙古巴林左旗乌尔吉等四幅1∶5万矿产调查项目中圈定的一处重要异常,为查明异常,内蒙古地质勘查基金立项,采用1∶1万地质、土壤、激电面积测量,配合1∶5 000地、物、化综合剖面测量、激电测深查证,经查证HZ-10异常浓集强度较高,浓集中心明显,各元素相互重叠,梯度较大,具明显矿致异常特征。激电异常IP1呈现高极化(视极化率值5%～7.9%),低阻异常特征。地表蚀变带呈褐黑色、褐黄色褐铁矿矿化、伴硅化,探槽(TCⅠ401)揭露铅矿化体连续刻槽样长度7.10 m,真厚度6.68 m,伴生银铅锌矿化,推断HZ-10异常由金属硫化物引起,矿致异常清晰。
The HZ-10 anomaly is an important anomaly delineated in four 1∶50,000 mineral exploration projects in Wuerji, Bairin Left Banner, Inner Mongolia. In order to identify the anomalous, 1∶10000 geological, soil, the induced voltage is measured with 1∶5000 ground, material and chemical comprehensive profile measurement, and the laser sounding depth verification. It is verified that the HZ-10 anomaly has a high concentration intensity, the concentration center is obvious, and the elements overlap each other, and the gradient is large. It has obvious mineral-induced anomalous characteristics. The IP abnormality IP1 exhibits high polarization(visual polarizability value 5% to 7.9%) and low resistance anomaly characteristics. The surface alteration zone is brownish-black, brownyellow limonite mineralized with silicification, and the trench(TCI401) reveals that the lead-stained body has a continuous groove sample length of 7.10 m and a true thickness of 6.68 m, associated with silver, lead and zinc mineralization. It is concluded that HZ-10 anomalies are caused by metal sulfides, and the minerals are abnormally clear.
