摘要
众所周知,中国是一个农业大国,而农业生产过程中所需钾肥的原材料钾盐是中国的紧缺矿种,中国70%的钾盐需要从国外进口,其中老挝就是中国政府进行钾盐勘探及开发的重要地区之一。老挝万象平原钾盐矿赋存于含盐系地层塔贡组中。由于对该套地层中各个亚层的地质特征认识不够,在矿产勘查过程中往往造成了人员、经费的浪费。本人有幸多年在该地区从事钾盐勘查工作,根据已有资料,整理、分析,对该套地层的各亚层的地质特点进行了总结。以便为各位从事老挝钾盐勘查的同仁们提供借鉴。
As we all know, China is a large agricultural country. Potassium salt, a raw material for potash fertilizer needed in agricultural production, is a shortage of minerals in China. 70% of China＇s potassium salt needs to be imported from abroad. Laos is one of the important areas for Chinese government＇s exploration and development of potash. Potassium salt deposits in the Vientiane Plain of Laos are found in the Tagon Formation of the salt-bearing strata. Due to the lack of understanding of the geological features of the sublayers in the formation, there is often a waste of personnel and funds in the mineral exploration process. I have been fortunate to have been engaged in potash exploration work in this area for many years. Based on the available data, I have collated and analyzed the geological characteristics of the sublayers of the formation. In order to provide reference for colleagues in Laos engaged in potassium salt exploration.
