摘要
老挝万象平原不同矿区盐丘构造发育程度不同。由于盐丘控制了钾盐矿层的分布,因此研究盐丘及其发育程度并对其分级,对万象平原及其周边地区的钾盐找矿具有重要参考意义。通过对万象平原大量的钾盐勘查资料研究,将该区域内盐丘构造按发育程度不同分为Ⅲ级(较发育)、Ⅱ级(发育)和Ⅰ级(极发育)三个级别。属Ⅲ级的有通芒盐丘和班海盐丘,属Ⅱ级的有农刀及塔贡盐丘,属Ⅰ级的为农哈湖盐丘。在万象平原进行钾盐勘查时,发育程度不同的盐丘及盐丘的不同部位的工程布设不同,找矿效果也不同。
The structure development degree of salt mound is different in different mining areas of Vientiane Plain, Laos. Because salt mound controls the distribution of potash ore beds, it is of great significance to study salt mound and its development degree and classify it for potash-salt prospecting in Vientiane Plain and its surrounding areas. Based on a large amount of potash exploration data in Vientiane Plain, the salt mound structure in this area is divided into three grades according to different developmental degrees: grade Ⅲ(relatively developed), grade Ⅱ(developmental) and grade Ⅰ(extreme development). Tongmang salt dome and Banhai salt dome belong to the grade III, the NongDao and Tagong salt dome belong to grade II, the Nongha Lake salt dome belongs to grade I. When potash exploration is carried out in Vientiane Plain, the different development degree of salt dome and different parts of salt dome have different engineering layout, and the prospecting effect is also different.
