直流电法在甲基卡稀有矿床外围地区寻找隐伏性岩脉的应用

Application of DC electrical method in prospecting hidden veins around the rare metal deposit of Jiajika

随着以锂为代表的新能源金属应用越来越受到重视,寻找锂矿资源将日益显得重要。为了实现在隐伏地区找矿突破的目的,以四川甲基卡稀有矿床外围容须卡地区为例,应用直流电法勘探圈定隐伏伟晶岩脉,在区内圈定了3个北西向高阻异常带,其中J3号高阻异常与已知R2含锂伟晶岩脉吻合较好,J1、J2两个高阻异常局部见伟晶岩体出露,推测异常由隐伏伟晶岩脉引起;进而寻找甲基卡式锂矿,以期能够对相关区域的隐伏型甲基卡式锂矿的有效探测提供参考和指导。

As more attention is paid to new energy metal application represented by lithium,looking for lithium resources will become increasingly significant. In order to achieve the goal in mineral exploration in concealed areas,DC electrical method is applied to explore and delineate the pegmatite veins in Rongxuka around Jiajika rare metal deposit. Three NW-trending anomalies with high resistance are delineated in the area. Anomaly No. J3 with high resistance is coincidence with R2 containing lithium pegmatite veins among these 3 anomalies. Pegmatite outcroppings are found in anomaly No. J1 and J2 partly,indicating that the anomaly is caused by hidden pegmatite veins. It can not only be the prospecting indicator for searching Jiajika typed lithium deposit,but also the effective references and guidance for relevant area in prospecting the hidden Jiajika typed lithium deposit.
